The 1915 Iowa State Census is a unique document. It was the first census in the United States to include information on education and income prior to the United States Federal Census of 1940. It contains considerable detail on other aspects of individuals and households, e.g., religion, wealth and years in the United States and Iowa. The Iowa State Census of 1915 was a complete sample of the residents of the state and the returns were written by census takers (assessors) on index cards. These cards were kept in the Iowa State Archives in Des Moines and were microfilmed in 1986 by the Genealogical Society of Salt Lake City. The census cards were sorted by county, although large cities (those having more than 25,000 residents) were grouped separately. Within each county or large city, records were alphabetized by last name and within last name by first name. This data set includes individual-level records for three of the largest Iowa cities (Des Moines, Dubuque, and Davenport; the Sioux City films were unreadable) and for ten counties that did not contain a large city. (Additional details on sample selection are available in the documentation). Variables include name, age, place of residence, earnings, education, birthplace, religion, marital status, race, occupation, military service, among others. Data on familial ties between records are also included.

The Building Strong Families (BSF) project examined the effectiveness of programs designed to improve child well-being and strengthen the relationships of low-income couples through relationship skills education. It surveyed couples 15 months and 36 months after having applied to and been accepted into a Building Stronger Families (BSF) program at one of eight locations offering services to unwed couples expecting, or having recently had a baby. Major topics included family structure, parental involvement with children, relationships, personal and parental well-being, utilization of services such as workshops to help their relationship and parenting skills, paternity and child support, and family self-sufficiency. Respondents were asked for information on recently born children and relationship status, how much time they spent with their children, their level of satisfaction with their current relationship, substance use, if they had attended relationship and parental counseling, whether they were legally required to provide child support, employment, and family background. Additional information was asked about domestic violence and child abuse, legal trouble, past sexual history, and child development. The 36-month data collection effort also included direct assessments of parenting and child development. The quality of the parenting relationship was assessed for both mothers and fathers and was based on a semi-structured play activity, "the two-bag task." This interaction was videotaped and later coded by trained assessors on multiple dimensions of parenting. During assessments with mothers, the focal child's language development was also assessed using the Peabody Picture Vocabulary Test. Demographic data includes race, education level, age, income, and marital status. The data collection is comprised of seven parts. Part 1: the BSF Eligibility and Baseline Survey Data file; Part 2: the BSF 15-Month Follow-up Survey Data file; Part 3: the program participation data file; Part 4: the BSF 15-month follow-up analysis file; Part 5: the BSF 36-Month Follow-up Survey Data file; Part 6: the mother-child in-home assessment; and Part 7: the BSF 36-Month Follow-up analysis file.

The California Families Project (CFP) is an ongoing longitudinal study of Mexican origin families in Northern California. This study uses community, school, family, and individual characteristics to examine developmental pathways that increase risk for and resilience to drug use in Mexican-origin youth. This study also examines the impact that economic disadvantage and cultural traditions have in Mexican-origin youth. The CFP includes a community-based sample of 674 families and children of Mexican origin living in Northern California, and includes annual assessments of parents and children. Participants with Mexican surnames were drawn at random from school rosters of students during the 2006-2007 and 2007-2008 school year. Data collection included multi-method assessments of a broad range of psychological, familial, scholastic, cultural, and neighborhood factors. Initiation of the research at age 10 was designed to assess the focal children before the onset of Alcohol, Tobacco, and Other Drug (ATOD) use, thus enabling the evaluation of how hypothesized risk and resilience mechanisms operate to exacerbate early onset during adolescence or help prevent its occurrence. This study includes a diversity of families that represent a wide range of incomes, education, family history, and family structures, including two-parent and single-parent families. The accompanying data file consists of 674 family cases with each case representing a focal child and at least one parent (Two-parent: n=549, 82 percent; Single-parent: n=125, 18 percent). Of the 3,139 total variables, 839 pertain to the focal child, 1,376 correspond to the mother, and 908 items pertain to the father. Please note: While the California Families Project is a longitudinal study, only the baseline data are currently available in this data collection.

Cape Area Panel Study (CAPS) is a longitudinal study of the lives of 4,800 young adults in Cape Town, South Africa. The Wave I sample was a representative sample of young people who were age 14 to 22 in 2002. In addition to interviews with these young people, the survey included information on all household members, non-resident children of household members, and non-resident parents and grandparents of the young adults. The Wave I survey covered topics such as school, work, health, sexual activity, and fertility, including an extensive life history calendar.

This extraction of data from 1980 decennial Census files (CENSUS OF POPULATION AND HOUSING, 1980 [UNITED STATES]: SUMMARY TAPE FILES 3A AND 3B [ICPSR 8071, 8318]) was designed to provide a set of contextual variables to be matched to any survey dataset that has been coded for the geographic location of respondents, such as the PANEL STUDY OF INCOME DYNAMICS, 1968-1988 (ICPSR 7439). This geographic area data can also be analyzed independently with neighborhoods, labor market areas, etc., as the units of analysis. Over 120 variables were selected from the original Census sources, and more than 100 variables were derived from those component variables. The variables characterize geographic areas in terms of population counts, ethnicity, family structure, income and poverty, education, residential mobility, labor force activity, and housing. The geographic areas range from neighborhoods, through intermediate levels of geography, through large economic areas, and beyond to large regions. These variables were selected from the Census data for their relevance to problems associated with poverty and income determination, and 80 percent were present in comparable form in both the 1970 and 1980 Census datasets.

This extraction of data from the 1990 decennial Census files (CENSUS OF POPULATION AND HOUSING, 1990 [UNITED STATES]: SUMMARY TAPE FILES 3A AND 3B [ICPSR 9694, 9693]) was designed to provide a set of contextual variables to be matched to any survey dataset that has been coded for the geographic location of respondents. Over 120 variables were selected from original Census sources, and more than 100 variables were derived from those component variables. The variables characterize geographic areas in terms of ethnicity, family structures, income, education, labor force activity, and housing. The geographic areas chosen range from neighborhoods (tracts, Block Numbering Areas [BNAs], and Enumeration Districts [EDs]), through intermediate levels of geography (Minor Civil Divisions and Census County Divisions [MCDs/CCDs], census places, and ZIP codes), through large economic areas (counties, Metropolitan Statistical Areas, State Economic Areas [SEAs], and specially created Labor Market Areas [LMAs]), and beyond to large regions (Economic Sub-Regions [ESRs] and states). To the maximum extent possible, the investigator selected Census variables that seemed relevant to problems associated with poverty and income determination and that were present in comparable form in the 1970 and 1980 Census datasets.

Children of Immigrants Longitudinal Study (CILS) was designed to study the adaptation process of the immigrant second generation which is defined broadly as United States-born children with at least one foreign-born parent or children born abroad but brought at an early age to the United States. The original survey was conducted with large samples of second-generation immigrant children attending the 8th and 9th grades in public and private schools in the metropolitan areas of Miami/Ft. Lauderdale in Florida and San Diego, California. Conducted in 1992, the first survey had the purpose of ascertaining baseline information on immigrant families, children's demographic characteristics, language use, self-identities, and academic attainment. The total sample size was 5,262. Respondents came from 77 different nationalities, although the sample reflects the most sizable immigrant nationalities in each area. Three years later, corresponding to the time in which respondents were about to graduate from high school, the first follow-up survey was conducted. Its purpose was to examine the evolution of key adaptation outcomes including language knowledge and preference, ethnic identity, self-esteem, and academic attainment over the adolescent years. The survey also sought to establish the proportion of second-generation youths who dropped out of school before graduation. This follow-up survey retrieved 4,288 respondents or 81.5 percent of the original sample. Together with this follow-up survey, a parental survey was conducted. The purpose of this interview was to establish directly characteristics of immigrant parents and families and their outlooks for the future including aspirations and plans for the children. Since many immigrant parents did not understand English, this questionnaire was translated and administered in six different foreign languages. In total, 2,442 parents or 46 percent of the original student sample were interviewed. During 2001-2003, or a decade after the original survey, a final follow-up was conducted. The sample now averaged 24 years of age and, hence, patterns of adaptation in early adulthood could be readily assessed. The original and follow-up surveys were conducted mostly in schools attended by respondents, greatly facilitating access to them. Most respondents had already left school by the time of the second follow-up so they had to be contacted individually in their place of work or residence. Respondents were located not only in the San Diego and Miami areas, but also in more than 30 different states, with some surveys returned from military bases overseas. Mailed questionnaires were the principal source of completed data in this third survey. In total, CILS-III retrieved complete or partial information on 3,613 respondents representing 68.9 percent of the original sample and 84.3 percent of the first follow-up.Relevant adaptation outcomes measured in this survey include educational attainment, employment and occupational status, income, civil status and ethnicity of spouses/partners, political attitudes and participation, ethnic and racial identities, delinquency and incarceration, attitudes and levels of identification with American society, and plans for the future.

These data, collected in Shanghai and Tianjin, China, in 1993, describe respondents' housing conditions and residential histories as well as family composition and family relations, work and work histories, and neighbor relations and neighborhood conditions. The unit of analysis is households, of which 2,096 participated: 1,054 in Shanghai and 1,042 in Tianjin. The survey elicited information on length of stay and frequency of moves, physical style of housing and organization of housing space, accessibility of utilities, amount of rent/payment and work unit subsidies, strategies for obtaining better housing, and neighborhood support networks. Other items covered income, job opportunity, housing allocation, collective welfare programs, employee training programs, relationship with others in the work unit and with the work unit leader, membership in the Communist party and the Youth League, and number of job changes. Background information on respondents includes age, ethnicity, sex, religion, education, number of siblings, number of parents living, marital status, number of children, health conditions, household income, employment status, political affiliation, occupation, number of employees in work unit, and division of housework within the household.

The China Multi-Generational Panel Dataset - Liaoning (CMGPD-LN) is drawn from the population registers compiled by the Imperial Household Agency (neiwufu) in Shengjing, currently the northeast Chinese province of Liaoning, between 1749 and 1909. It provides 1.5 million triennial observations of more than 260,000 residents from 698 communities. The population mainly consists of immigrants from North China who settled in rural Liaoning during the early eighteenth century, and their descendants. The data provide socioeconomic, demographic, and other characteristics for individuals, households, and communities, and record demographic outcomes such as marriage, fertility, and mortality. The data also record specific disabilities for a subset of adult males. Additionally, the collection includes monthly and annual grain price data, custom records for the city of Yingkou, as well as information regarding natural disasters, such as floods, droughts, and earthquakes. This dataset is unique among publicly available population databases because of its time span, volume, detail, and completeness of recording, and because it provides longitudinal data not just on individuals, but on their households, descent groups, and communities.

The China Multi-Generational Panel Dataset - Shuangcheng (CMGPD-SC) provides longitudinal individual, household, and community information on the demographic and socioeconomic characteristics of a resettled population living in Shuangcheng, a county in present-day Heilongjiang Province of Northeastern China, for the period from 1866 to 1913. The dataset includes some 1.3 million annual observations of over 100,000 unique individuals descended from families who were relocated to Shuangcheng in the early 19th century. These families were divided into 3 categories based on their place of origin: metropolitan bannermen, rural bannermen, and floating bannermen. The CMGPD-SC, like its Liaoning counterpart, the CMGPD-LN (ICPSR 27063), is a valuable data source for studying longitudinal as well as multi-generational social and demographic processes. The population categories had salient differences in social origins and land entitlements, and landholding data are available at a number of time periods, thus the CMGPD-SC is especially suitable to the study of stratification processes.

The Chitwan Valley Family Study (CVFS) is a comprehensive family panel study of individuals, households, and communities in the Chitwan Valley of Nepal. The study was initially designed to investigate the influence of changing community and household contexts on population outcomes such as marital and childbearing processes. Over time, the goals of the study expanded to investigate family dynamics, intergenerational influences, child health, migration, labor force participation, attitudes and beliefs, mental health, agricultural production, environmental change, and many other topics. The data include full life histories for more than 10,000 individuals, tracking and interviews with all migrants, continuous measurement of community change, over 25 years of demographic event registry, and many other data collections. For additional information regarding the Chitwan Valley Family Study, please visit the Chitwan Valley Family Study Website. A Data Guide for this study is available as a webpage and for download.

The Community Healthy Marriage Initiative (CHMI) evaluation was designed to evaluate community-level impacts of various relationship and marriage education programs. This study compared three sites which received grant funding from the Administration for Children and Families (ACF) (Dallas, Texas; St. Louis, Missouri; and Milwaukee, Wisconsin) with three cities that did not receive grant-funding (Fort Worth, Texas; Kansas City, Missouri; and Cleveland, Ohio) to determine what impacts grant funding has on these types of programs. This collection includes two rounds of surveys, one conducted in 2007 and one conducted in 2009, for longitudinal comparison. Respondents were asked a series of questions regarding their knowledge of relationship and marriage education programs in their area, including where they had learned of the classes, what source of advertising they had heard or seen, whether they knew where the classes were held, and whether they had discussed the classes with someone else. Information was collected to gauge respondents' participation in these courses, including whether they had taken a class in the previous 18 months, how long they attended the courses, whether they had received other services as a result of attending the classes, and whether they had suggested the classes to someone else. Respondents were also queried on whether they would be interested in attending a relationship class or a parenting class. Additional topics included parental relationships with their children, and relationship quality. Demographic variables include relationship status, household composition, employment status, parental status, race, age, and household income.

The East Asian Social Survey (EASS) is a biennial social survey project that serves as a cross-national network of the following four General Social Survey type surveys in East Asia: the Chinese General Social Survey (CGSS), the Japanese General Social Survey (JGSS), the Korean General Social Survey (KGSS), and the Taiwan Social Change Survey (TSCS), and comparatively examines diverse aspects of social life in these regions. Since its 1st module survey in 2006, EASS produces and disseminates its module survey datasets and this is the harmonized data for the 4th module survey, called 'Network Social Capital in East Asia,' which was carried out in 2012 in the four countries. Survey information in this module focuses on social networks and participation and attitudes toward various social organizations and events. Respondents were asked about common social interactions, family structures and relationships, their neighborhood environments, social support systems, and their trust toward a range of community members and institutions. Additionally, respondents were asked for their opinions on political issues, and about their participation and experience with voting in recent elections. Demographic and other background information includes age, sex, marital status, religion, years of education completed, employment status, income, and household size and composition.

This study focused on household living arrangements of parents and adult children during times of financial instability. A survey of over 3,000 adults aged 18 years and older from the general population was conducted by Knowledge Networks on behalf of the National Center for Family and Marriage Research. The survey was completed by 3,132 respondents out of 4,478 cases (69.9 percent response rate). Measures include variables on financial responsibility between children and parents and a vignette on an adult child living with his parents.

This study focused on how financial difficulties may hinder or facilitate sound financial management. A survey of 1,000 adults aged 18 years and older from the general population was conducted by Knowledge Networks on behalf of the National Center for Family and Marriage Research. The survey was completed by 1,014 respondents out of 1,517 cases (66.8 percent response rate). Although financial behavior research is common in the literature, no financial behavior scale exists that is both multi-dimensional and psychometrically validated. Using data from a national sample, this study developed and examined the psychometric properties of a new scale of financial management behaviors. The Financial Behavior Scale (FBS) displayed adequate reliability (alpha = .81). Further, it was highly associated with other measures of financial behavior and discriminated between financial behaviors and time use behaviors. Finally, the scale was highly predictive of savings, consumer debt, and investments. Thus, the FBS appears to be a reliable and valid scale of financial behaviors.

This study focused on how families respond to financial instability and economic pressure. A survey of over 1,000 adults aged 18 years and older who have a child younger than 18 years at home was conducted by Knowledge Networks on behalf of the National Center for Family and Marriage Research. The survey was completed by 1,169 respondents out of 1,855 cases (63 percent response rate). In addition to the main survey, respondents were also administered a one-question survey about insurance. Along with the survey variables from the main and the one-question surveys, Knowledge Networks' standard profile, and a series of data processing variables created by Knowledge Networks are included in the data file for the eligible cases (n = 1,169). Measures included variables regarding income, financial stability, borrowing money, main expenditures, and health care coverage.

On behalf of the National Center for Family and Marriage Research, Knowledge Networks conducted a survey about financial management behaviors among 600 opposite sex married or cohabiting couples. Both partners were invited to participate in the survey at the same time. The data collection began on August 18, 2009, and continued through August 24, 2009. A total of 2,495 panelists were invited to participate in the survey. Among the 1,595 (64%) who responded to the survey, 1,264 (51%) were eligible and completed the questionnaire. Measures included variables on partner/relationship satisfaction, financial problems, and blame.

The Family Exchanges Study Wave 1 (FESI) was conducted in 2008 by the Institute for Survey Research at Temple University. The original 634 "target" or core sample was recruited from African American and White respondents aged 40-60 living in Philadelphia and the surrounding counties--Bucks, Chester, Delaware, and Montgomery. To be eligible for the study, respondents had to have at least one living parent and one living offspring over 18 years of age. Temple University sought to recruit the parents, spouse, and up to three offspring over 18 years of age into the study. All target, parent, and spouse surveys were conducted by telephone. Offspring were given the option of completing the survey by telephone or web. A total of 337 parents, 511 offspring (with another 80 by web and 1 listed as other for a total of 592), and 197 spouses were successfully recruited into the first wave of the study. This collection includes four data files, one for each type of participant: target, spouse, parent, and offspring. For each of these participants, there are data related to relationships with other family members, perceptions of family members, and views on key social issues. Demographic information includes gender, marital status, education level, religion, age, race, ethnicity, and employment status.

Offspring were given the option of completing the survey by telephone or web. For the Wave 2 data collection, the Survey Research Center at Pennsylvania State University attempted to contact all FESI respondents again, as well as collect updated information for spouses/romantic partners, parents, and up to 4 age-eligible offspring. The survey instruments were drawn largely from the first wave of data collection. This collection includes eight data files. These data files include five main study datasets: target, spouse, spouse without target, parent, and offspring. This collection also includes three diary datasets: target diary, parent diary, offspring diary. For each participant, there are data related to relationships with other family members, perceptions of family members, and views on key social issues. Demographic information includes gender, marital status, education level, religion, age, race, ethnicity, and employment status.

The First Malaysian Family Life Survey, 1976-1977 (MFLS-1), was conducted in Peninsular Malaysia as a retrospective life history survey of 1,262 households containing an ever-married woman aged 50 or younger. Full life histories were collected through personal interviews with these women and their husbands regarding fertility-related events, marriage, employment, migration, income and wealth, attitudes and expectations with respect to family size and composition, community characteristics, time allocation, and transfers of goods, help, and money between the respondents and others. The survey collected data in three separate rounds held at four-month intervals. The majority of the survey was administered in Round 1, while the second and third rounds collected data on new questions not asked in Round 1 and also updated some of the Round 1 data, most notably the work and pregnancy histories. In October 1981, the individual-level dataset (Part 142) was created, consisting of one fixed-length record per individual per household. Variables included at both the individual and household levels provide information on demographics, time allocation, and income and wealth. Due to processing constraints, most of the retrospective data have been omitted from the individual-level dataset.

The Future of Families and Child Wellbeing Study (FFCWS, formerly known as the Fragile Families and Child Wellbeing Study) follows a cohort of nearly 5,000 children born in large, U.S. cities between 1998 and 2000. The study oversampled births to unmarried couples; and, when weighted, the data are representative of births in large U.S. cities at the turn of the century. The FFCWS was originally designed to address four questions of great interest to researchers and policy makers: What are the conditions and capabilities of unmarried parents, especially fathers? What is the nature of the relationships between unmarried parents? How do children born into these families fare? How do policies and environmental conditions affect families and children? The FFCWS consists of interviews with mothers, fathers, and/or primary caregivers at birth and again when children are ages 1, 3, 5, 9, 15, and 22. The parent interviews collected information on attitudes, relationships, parenting behavior, demographic characteristics, health (mental and physical), economic and employment status, neighborhood characteristics, and program participation. Beginning at age 9, children were interviewed directly (either during the home visit or on the telephone). The direct child interviews collected data on family relationships, home routines, schools, peers, and physical and mental health, as well as health behaviors. A collaborative study of the FFCWS, the In-Home Longitudinal Study of Pre-School Aged Children (In-Home Study) collected data from a subset of the FFCWS Core respondents at the Year 3 and 5 follow-ups to ask how parental resources in the form of parental presence or absence, time, and money influence children under the age of 5. The In-Home Study collected information on a variety of domains of the child's environment, including: the physical environment (quality of housing, nutrition and food security, health care, adequacy of clothing and supervision) and parenting (parental discipline, parental attachment, and cognitive stimulation). In addition, the In-Home Study also collected information on several important child outcomes, including anthropometrics, child behaviors, and cognitive ability. This information was collected through interviews with the child's primary caregiver, and direct observation of the child's home environment and the child's interactions with his or her caregiver. Similar activities were conducted during the Year 9 follow-up. At the Year 15 follow-up, a condensed set of home visit activities were conducted with a subsample of approximately 1,000 teens. Teens who participated in the In-Home Study were also invited to participate in a Sleep Study and were asked to wear an accelerometer on their non-dominant wrist for seven consecutive days to track their sleep (Sleep Actigraphy Data) and that day's behaviors and mood (Daily Sleep Actigraphy and Diary Survey Data). An additional collaborative study collected data from the child care provider (Year 3) and teacher (Years 9 and 15) through mail-based surveys. Saliva samples were collected at Year 9 and 15 (Biomarker file and Polygenic Scores). The Study of Adolescent Neural Development (SAND) COVID Study began data collection in May 2020 following the onset of the COVID-19 pandemic. It included online surveys with the young adult and their primary caregiver. The FFCWS began, its seventh wave of data collection in October 2020, around the focal child's 22nd birthday. Data collection and interviews continued through January 2024. The Year 22 wave included a young adult (YA) survey with the original focal child and a primary caregiver (PCG) survey. Data were also collected on the children of the original focal child (referred to as Generation 3, or G3). Documentation for these files is available on the FFCWS website located here. For details of updates made to the FFCWS data files, please see the project's Data Alerts page. Data collection for the Future of Families and Child Wellbeing Study was supported by the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) of the National Institutes of Health under award numbers R01HD36916, R01HD39135, and R01HD40421, as well as a consortium of private foundations.

The Guatemalan Survey of Family Health (EGSF) was undertaken to investigate the health of children under the age of five and women during pregnancy and childbirth residing in 60 communities within the departments (geopolitical units) of Chimaltenango, Suchitepequez, Totonicapan, and Jalapa in Guatemala. Data were collected at the household, individual, and community levels to gain an in-depth understanding of the way residents in these rural populations think about their health, treatment, and family relations. Data at the household level (Parts 1-5, 90-92) provide information on household members, relation to household head, age, education, and language used. The individual-level data (Parts 6-37) describe the respondent's background, marital/relationship history, social ties and social support, and economic status, along with health beliefs, a complete birth history, knowledge and use of contraception, health problems and treatment during the last two pregnancies, and anthropometry on mothers and children. Extensive data were gathered regarding the health problems and treatment for each of the two youngest children born since January 1990, with particular focus on diarrhea and respiratory infections. The community data (Parts 41-60) supply information gathered from three knowledgeable individuals called "key informants" about occupations in the community, crops grown, wages, utilities and community services, and the history of the community. Parts 61-89 contain information regarding Health Posts (health care centers) through interviews conducted with key informants, doctors (Parts 72-80), and other health service providers (Parts 81-89), including traditional providers such as curers, midwives, and bone setters, regarding their practices, patients, referrals, fees, payment, and the use of specific treatments.

IIMMLA was supported by the Russell Sage Foundation. Since 1991, the Russell Sage Foundation has funded a program of research aimed at assessing how well the young adult offspring of recent immigrants are faring as they move through American schools and into the labor market. Two previous major studies have begun to tell us about the paths to incorporation of the children of contemporary immigrants: The Children of Immigrants Longitudinal Study (CILS), and the Immigrant Second Generation in New York study. The Immigration and Intergenerational Mobility in Metropolitan Los Angeles study is the third major initiative analyzing the progress of the new second generation in the United States. The Immigration and Intergenerational Mobility in Metropolitan Los Angeles (IIMMLA) study focused on young adult children of immigrants (1.5- and second-generation) in greater Los Angeles. IIMMLA investigated mobility among young adult (ages 20-39) children of immigrants in metropolitan Los Angeles and, in the case of the Mexican-origin population there, among young adult members of the third- or later generations. The five-county Los Angeles metropolitan area (Los Angeles, Orange, Ventura, Riverside and San Bernardino counties) contains the largest concentrations of Mexicans, Salvadorans, Guatemalans, Filipinos, Chinese, Vietnamese, Koreans, and other nationalities in the United States. The diverse migration histories and modes of incorporation of these groups made the Los Angeles metropolitan area a strategic choice for a comparison study of the pathways of immigrant incorporation and mobility from one generation to the next. The IIMMLA study compared six foreign-born (1.5-generation) and foreign-parentage (second-generation) groups (Mexicans, Vietnamese, Filipinos, Koreans, Chinese, and Central Americans from Guatemala and El Salvador) with three native-born and native-parentage comparison groups (third- or later-generation Mexican Americans, and non-Hispanic Whites and Blacks). The targeted groups represent both the diversity of modes of incorporation in the United States and the range of occupational backgrounds and immigration status among contemporary immigrants (from professionals and entrepreneurs to laborers, refugees, and unauthorized migrants). The surveys provide basic demographic information as well as extensive data about socio-cultural orientation and mobility (e.g., language use, ethnic identity, religion, remittances, intermarriage, experiences of discrimination), economic mobility (e.g., parents' background, respondents' education, first and current job, wealth and income, encounters with the law), geographic mobility (childhood and present neighborhood of residence), and civic engagement and politics (political attitudes, voting behavior, as well as naturalization and transnational ties).

The India Human Development Survey (IHDS) is a nationally representative, multi-topic survey of 42,152 households in 1,503 villages and 971 urban neighborhoods across India. Data were originally collected from households during 2004-2005. Interviewers returned in 2011-2012 to re-interview these same households. During both waves of data collection, two one-hour interviews were conducted covering a large range of topics. The goal of the IHDS program is to document changes in the daily lives of Indian households in a society undergoing rapid transition. This particular data collection merges the two waves of IHDS (known as IHDS and IHDS-II) into a harmonized pattern from the perspective view points of individuals, households, and eligible women. The data are presented in three different data formats: cross-sectional, wide, and long to facilitate a broader range of analysis options. Due to the specificity of geography and inclusion of sensitive / identifying topics there is a public-use and restricted-use rendition for each of the nine data files.

This release of the 1993 Indonesian Family Life Survey (IFLS-1-PR) is a revised and restructured version of the Wave 1 data. This data collection provides a broad range of economic, demographic, and health information at both the household and community levels across 13 provinces on the islands of Java, Sumatra, Bali, West Nusa Tenggara, Kalimantan, and Sulawesi. A sample of 7,224 households was interviewed during August 1993 through January 1994. Household-level data cover topics such as household characteristics, income, education of both adults and children, marriage histories, inter-household transfers, pregnancy history, and knowledge and use of contraceptives. At the community-facility level, information was gathered from village leaders and heads of village women's groups in each of the 321 enumeration areas (EAs) where the households were located. Questions were asked regarding community characteristics (transportation, water and sanitation, history of schools, and availability of health facilities), nurses, midwives, and paramedics (facility management and family planning history, vignettes on types of care), and traditional health practitioners (buying or making herbal medicines or using services of traditional practitioners, rituals, and incantations). When the household data are combined with the community-facility data, the 1993 Indonesian Family Life Survey provides a unique look at areas of fertility, family planning, infant and child health, education, migration, employment, and the social, economic, and health status of over 7,000 households in a diverse setting during a period of rapid demographic and socioeconomic change. As of June 2015, there are four waves of data for the IFLS. However, a fifth wave of data collection has begun. Please see the IFLS Web site for more information on how to obtain these data.

These data explore the family relationships and social support networks of middle-aged and older persons. Information on respondents' relationships with individual family members is supplied, along with measures of many kinds of routine help given and received, and summary measures of the amount of time that others spent helping the respondent and that the respondent spent helping others. Variables cover respondent's employment status and history, employment status and history of respondent's spouse, respondent's income, number and sex of children, family composition (biological parents, step-parents, in-laws), household chores performed (cooking, cleaning, washing, shopping, driving), and assistance received with chores. Additional items relate to whether respondents helped anyone else with daily activities, and whether they were involved in church, civic, and/or other activities. Demographic information about respondents and their spouses (age, sex, education, ethnicity) is also provided.

The International Social Survey Program (ISSP) is an ongoing program of cross-national collaboration. Formed in 1983, the ISSP group develops topical modules dealing with important areas of social science as supplements to regular national surveys. This data collection is the third survey exploring the topic of family and changing gender roles. Participating countries in the 2002 survey included Austria, Australia, Brazil, Bulgaria, Chile, Cyprus, Czech Republic, Denmark, Finland, Flanders (Belgium), France, Germany (West and East), Great Britain, Hungary, Ireland, Israel, Japan, Latvia, Mexico, Netherlands, New Zealand, Northern Ireland, Norway, Philippines, Poland, Portugal, Russia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Taiwan, and the United States. Respondents were queried on various topics regarding the family, relationships with spouse or other partner(s), marriage, divorce, child rearing, single parenting, changing gender roles in the home and workplace, fulfilling family responsibilities, division of housework, management of household income, working parents (particularly working mothers), job-related stress, and job satisfaction. Demographic variables include sex, age, ethnicity or nationality, marital status, level of education, current employment status, family income, number of people living in household, household composition, religious denomination, trade union membership, political party affiliation, and region of the country and size of community where currently residing.

This collection, the fourth module in the ISSP series, contains data from Austria, the Federal Republic of Germany, Hungary, Ireland, Italy, the Netherlands, Great Britain, and the United States. Questions asked of respondents focused on the family and changing sex roles. Respondents were asked for their views on women working outside the home (especially working mothers), childcare arrangements and child rearing practices, marriage, family structure and composition, and divorce. Demographic data on respondents, such as age, sex, race, ethnic identity, employment, income, marital status, education, religion, political affiliation, voting behavior, trade union membership, and household size, also were recorded. Information gathered about each person in the household includes sex, age, and relationship to the respondent.

This data collection is a sociohistorical study of the ways in which three generations (Issei, Nisei, and Sansei) of Japanese American families adapted to social, cultural, educational, occupational, and other institutions of American life. The study examines the experience of the first immigrants to the United States (Issei), and their children (Nisei) and grandchildren (Sansei). Interviews with Issei families stressed the difficulties faced by the immigrants during their early years in the United States, as well as aspects of social and cultural life. Interviews with Nisei included questions on employment, attitudes toward work, income, education, marriage, social relationships, discrimination, and religion. Topics covered in Sansei interviews included birth order, age, marital status, children, social relationships, occupation, industry, income, education, Japanese value systems, marital choices, influence of parents and grandparents, discrimination, religion, political attitudes, and migration.

This survey, based on the General Social Survey in the United States, was designed to solicit political, sociological, and economic information from people living in Japan. Questions on crime and the judicial system queried respondents about the death penalty and the appropriateness of punishments given to juvenile and adult offenders, whether respondents had ever been punched or beaten, whether respondents had been victims of robberies within the last year, and whether there was an area, within one kilometer of their homes, where respondents were afraid to venture. Questions on family issues covered topics such as when divorce was the best course of action for those involved, the frequency that families dined together and performed household chores, the health of respondents' marriages, the roles of spouses within marriage, whether one or both spouses should change their surnames, the ideal number of children a couple should have, whether there was a sex preference for children, whether the respondents had pets and the benefits of pet ownership, where respondents would like to be buried, and whether in some cases, physical punishment of children by parents or teachers was acceptable. Questions on finances included items on the state of respondents' finances during the last few years, how their family's income compared to other Japanese families, how their family's income compared to that of Japanese families 15 years ago, whether the income tax rate was high, the amount of pension respondents would receive upon retirement, how respondents' families organized their finances, and the ease of improving one's standard of living in Japan. Political questions addressed whether the government should be responsible for the livelihood and medical care of the elderly, whether the government was usurping individual responsibilities, whether respondents would vote for a woman gubernatorial candidate, government spending, respondents' commitment and sense of belonging to the political process, and whether one of the government's duties was to reduce family income disparities. Also, respondents were asked to rate their political views on a scale from Conservative (1) to Progressive (5). In terms of health, information was solicited on the health of respondents and their spouses, whether a doctor should be able to painlessly end a patient's life if the patient's condition was terminal, whether respondents had signed organ donation cards, and the frequency of smoking, alcohol consumption, and sexual relations in the last 12 months. Quality of life questions addressed the frequency with which respondents read the newspaper, the average number of books respondents read per month, the average number of hours respondents watched television, whether respondents attended any job- or hobby-related classes, the amount of satisfaction respondents received from life, the frequency respondents went on trips lasting at least two days, and how often respondents participated in leisure activities like fishing, jogging, mahjong, etc. Respondents were asked to give their opinions concerning a married person having sexual relations with someone other than their spouse, sexual relations between two adults of the same sex, whether pornography leads to the breaking down of morals, whether the client, the teen, both, or neither party was responsible for teen prostitution, and whether pornography should be banned completely, not available to anyone under 18, or not be regu,lated at all. Information gathered on religion included whether respondents believed in life after death and whether they and/or their spouses followed a religion and the extent of their participation. Respondents were polled for information regarding their social status, whether it was desirable for three generations of family to share a home, whether men should learn to cook and care for themselves, the trustworthiness of most people, the general motivations of others, whether respondents were members of any groups like religious, trade, or social service organizations, and to what degree respondents utilized technology like computers, e-mail, and the Internet to perform daily life tasks. Demographic information includes age, sex, employment status, marital status, household income, and religious orientation.

The Kinder Houston Area Survey is a longitudinal study that began in May 1982 after Houston, Texas, recovered from the recession of the mid-1980s. The overall purpose of this research was to measure systematically the public responses to the new economic, educational, and environmental challenges, and to make the findings of this continuing project readily available to civic and business leaders, to the general public, and to research scholars. Part 1, All Responses from 25 Successive Samples, contains all the responses from the successive representative samples of Harris County residents from 1982 through 2014. These are the data that enabled the project to analyze continuity and change among area residents over the course of 26 years. In 13 of the 14 surveys (the years from 1994 through 2014, the one exception being 1996), the surveys were expanded with oversample interviews in Houston's ethnic communities. Using identical random-selection procedures, and terminating after the first few questions if the respondent was not of the ethnic background required, additional interviews were conducted in each of the years to enlarge and equalize the samples of Anglo, African American, and Hispanic respondents at about 500 each. In 1995 and 2002, the research also included large representative samples (N=500) from Houston's Asian communities, with one-fourth of the interviews conducted in Vietnamese, Cantonese, Mandarin, or Korean -- the only such surveys in the country. These additional interviews are included in Part 2, Additional Oversample Interviews. The data contained in Part 2 are for Restricted-Use of Part 1, All Responses from 25 Successive Samples. The data contained in Part 3 are based on a 14-year total of 6,576 Anglos, 6,086 African Americans, 6,094 Hispanics, and 1,250 Asians, along with 387 others, and are of particular value in assessing the similarities and differences both within and among Houston's (and America's) four largest ethnic groups. Beginning in 2003, the data files have incorporated detailed information from the 2000 Census on the characteristics of the respondent's neighborhood, not only at the level of home ZIP code, but also by Census tract and block group. In Part 4, Restricted-Use information from 2000 Census, the data record the population and geographical area of each of the three sectors, distributions by ethnicity and immigrant status, age and gender composition, employment and commuting patterns, and levels of education and income. With this information incorporated in the datasets covering five years of expanded surveys, researchers are able to connect the respondents' perceptions and experiences with information on the neighborhoods in which they live, thereby adding a contextual dimension to analyses of the factors that account for individual differences in attitudes and beliefs. Conducted during February and March of each year, the interviews measured perspectives on the local and national economy, on poverty programs, inter-ethnic relationships. Also captured were respondents' beliefs about discrimination and affirmative action, education, crime, health care, taxation, and community service, as well as their assessments of downtown development, mobility and transit, land-use controls and environmental concerns, and their attitudes toward abortion, homosexuality, and other aspects of the social agenda. Also recorded were religious and political orientations, as well as an array ,of demographic and immigration characteristics, socioeconomic indicators, and family structures.

The Korean General Social Survey (KGSS) is the Korean version of the General Social Survey (GSS), closely replicating the original GSS of the National Opinion Research Center at the University of Chicago. Each round of KGSS typically includes the topical module of the International Social Survey Programme (ISSP), and/or the East Asian Social Survey (EASS), an international survey network of four GSS-type surveys in East Asia, (including China, Japan, Taiwan, and South Korea). Respondents were asked for their opinions on Korean society, politics and reunification, economic issues, social equity and inequality, and suicide. Additional questions were asked about the everyday life, household, family, education, occupation, and mental health of the respondents. Demographic information includes age, sex, education level, household income, employment status, religious preference, political party affiliation, and political philosophy.

Latin American Migration Project is a study to advance understanding of the complex processes of international migration and immigration to the United States. In addition to basic demographic data, the survey gathers information on family composition, fertility, infant mortality, household head marital history, labor history of the household head and his/her spouse, and ownership history of properties and businesses. Furthermore, detailed data on internal migration, migration to the mainland United States, and multiple aspects of key United States trips (work experience, income, social networks, remittances, welfare use, etc.) are also collected.

The Longitudinal Study of Generations (LSOG), initiated in 1971, began as a survey of intergenerational relations among 300 three-generation California families with grandparents (then in their sixties), middle-aged parents (then in their early forties), and grandchildren (then aged 15 to 26). The study broadened in 1991 and now includes a fourth generation, the great-grandchildren of these same families. The LSOG, with a fully elaborated generation-sequential design, allows comparisons of sets of aging parents and children at the same stage of life but during different historical periods. These comparisons make possible the investigation of the effects of social change on inter-generational solidarity or conflict across 35 years and four generations, as well as the effects of social change on the ability of families to buffer stressful life transitions (e.g., aging, divorce and remarriage, higher female labor force participation, changes in work and the economy, and possible weakening of family norms of obligation), and the effects of social change on the transmission of values, resources, and behaviors across generations. The LSOG contains information on family structure, household composition, affectual solidarity and conflict, values, attitudes, behaviors, role importance, marital relationships, health and fitness, mental health and well-being, caregiving, leisure activities, and life events and concerns. Demographic variables include age, sex, income, employment status, marital status, socioeconomic history, education, religion, ethnicity, and military service.

This study includes public user data files of two waves of interviews with L.A.FANS respondents. There often are multiple respondents in L.A.FANS households and Wave 2 includes both panel respondents and a new sample. Users' Guides which explain the design and how to use the sample are available for Wave 1 and Wave 2 at the RAND website. The Los Angeles Family and Neighborhood Survey (L.A.FANS) is a two-wave study of adults and children in Los Angeles County and of the neighborhoods in which they live. The first wave (L.A.FANS-1), which was fielded between April 2000 and January 2002, interviewed adults and children living in 3,085 households in a stratified probability sample of 65 neighborhoods throughout Los Angeles County. The samples of neighborhoods and individuals were representative of neighborhoods and residents of Los Angeles County. Poorer neighborhoods and households with children were oversampled. In Wave 2 of L.A.FANS (L.A.FANS-2), Wave 1 respondents living in Los Angeles County were reinterviewed and updated information was collected on Wave 1 respondents who had moved away from Los Angeles County. A sample of individuals who moved into each sampled neighborhood between Waves 1 and 2 was also interviewed, for a total of 2,319 adults and 1,382 children (ages less than 18 years). Additional information on the project is available at the RAND website.

This study includes a restricted data file for Wave 1 of the L.A.FANS data. To compare L.A.FANS restricted data, version 1 with other restricted data versions, see the table on the series page for the L.A.FANS data here. Data in this study are designed for use with the public use data files for L.A.FANS, Wave 1 (study 1). This file adds only a few variables to the L.A.FANS, Wave 1 public use files. Specifically, it adds a "pseudo-tract ID" which is a number from 1 to 65, randomly assigned to each census tract (neighborhood) in the study. It is not possible to link pseudo-tract IDs in any way to real tract IDs or other neighborhood characteristics. However, pseudo-tract IDs permit users to conduct analyses which take into account the clustered sample design in which neighborhoods (tracts) were selected first and then individuals were sampled within neighborhoods. Pseudo-tract IDs do so because they identify which respondents live in the same neighborhood. It also includes certain variables, thought to be sensitive, which are not available in the public use data. These variables are identified in the L.A.FANS Wave 1 Users Guide and Codebook. Finally, some distance variables and individual characteristics which are treated in the public use data to make it harder to identify individuals are provided in an untreated form in the Version 1 restricted data file. Please note that L.A. FANS restricted data may only be accessed within the ICPSR Virtual Data Enclave (VDE) and must be merged with the L.A. FANS public data prior to beginning any analysis.

Data in this study are designed for use with the public use data files for L.A.FANS, Wave 2 (study 2). This file adds only a few variables to the L.A.FANS, Wave 2 public use files. Specifically, it adds the census tract and block number for the tract each respondent lives in. It also includes certain variables, thought to be sensitive, which are not available in the public use data. These variables are identified in the L.A.FANS Wave 2 Users Guide and Codebook. Finally, some distance variables and individual characteristics which are treated in the public use data to make it harder to identify individuals are provided in an untreated form in the Version 2.5 restricted data file. Please note that L.A. FANS restricted data may only be accessed within the ICPSR Virtual Data Enclave (VDE) and must be merged with the L.A. FANS public data prior to beginning any analysis. A Users' Guide which explains the design and how to use the samples are available for Wave 2 at the RAND website.

This study includes a restricted data file, version 3, for Wave 2 of the L.A.FANS data. To compare L.A.FANS restricted data, version 3 with other restricted data versions, see the table on the series page for the L.A.FANS data here. Data in this study are designed for use with the public use data files for L.A.FANS, Wave 2 (study 2). This file adds only a few variables to the L.A.FANS, Wave 2 public use files. Specifically, it adds the census tract and block number for the tract each respondent lives in and geographic coordinates data for a number of locations reported by the respondent (including home, grocery store, place of work, place of worship, schools, etc.). It also includes certain variables, thought to be sensitive, which are not available in the public use data. These variables are identified in the L.A.FANS Wave 2 Users Guide and Codebook. Finally, some distance variables and individual characteristics which are treated in the public use data to make it harder to identify individuals are provided in an untreated form in the Version 3 restricted data file. Please note that L.A. FANS restricted data may only be accessed within the ICPSR Virtual Data Enclave (VDE) and must be merged with the L.A. FANS public data prior to beginning any analysis.
