The 2021-2022 Study of Family and Staff Well-Being in Head Start FACES Programs (2021-2022 study), builds on the Head Start Family and Child Experiences Survey (FACES), which has been a source of national information about Head Start programs and participants since 1997. The motivation and goals of the Study of Family and Staff Well-Being in Head Start Family and Child Experiences Survey Programs (the 2021-2022 study) came from a need that arose as the COVID-19 pandemic continued into another year of affecting Head Start families' and staff's lives. The 2021-2022 study included two components. Firstly, the Program, Staff, and Family Study , was conducted in 60 programs, and included the collection of parent surveys and Teacher Child Reports (TCRs) in fall 2021 and spring 2022, as well as a teacher survey in fall 2021. Secondly, the Program and Staff Study , conducted in the 60 programs participating in the Program, Staff, and Family Study plus an additional 120 programs, included the collection of program director, center director, and teacher surveys in spring 2022. The 2021-2022 study aimed to describe the national population of Head Start programs, centers, teachers, classrooms, and children during the 2021-2022 program year. However, the Data Producers were unable to fully meet this goal because of challenges related to the COVID-19 pandemic. A nationally representative sample of Head Start programs was selected. However, fewer of the programs participated than expected. Probability samples of centers, teachers, and children within the participating programs were selected. Weights are available for analysis to account for the probability that children and their teachers, centers, and programs were selected for the study. This lessens the risk of bias due to study non-participation and survey nonresponse; and provide results that represent, to the extent possible, all programs, centers, teachers, classrooms, and children in Head Start. The responding sample may not fully represent the population due to higher-than-expected non-response that may not have been adequately addressed with weighting adjustments. Despite these limitations, the 2021-2022 study sample design supports many analyses for programs and teachers, as well as children. The data from the programs in the Program, Staff, and Family Study can address questions about the children and parents who participate in the program, including about children's development across one year in the Head Start program for both newly entering children and those returning for a second year. The study also supports research questions related to subgroups of interest, such as families with low income and specific racial/ethnic groups, as well as policy issues that emerge during the study. In addition, the research questions investigate the characteristics of Head Start programs, centers, and teachers, and the classrooms they teach. Users can use the same data to answer questions about the relationships between program and classroom characteristics and child and family well-being. The data from the larger sample of programs in the Program and Staff Study are most useful for answering questions about Head Start programs, classrooms, teachers, and program and center directors.

This special topic poll was undertaken to gauge respondents' reactions and feelings regarding the recent allegations of sexual abuse of children by Catholic priests and cover-ups by the Catholic Church. The poll also attempted to assess how these allegations had influenced respondents' feelings about the Catholic Church in general. Respondents were asked if they had heard of the scandal surrounding Catholic priest John Geoghan, a Boston clergyman accused of molesting over 80 children, if the case had concerned them, how serious a problem they viewed sexual abuse of children by priests to be, and how often they thought that sexual abuse by priests occurred. Those queried were then asked if they thought the Catholic Church was doing enough to address the problem of sexual abuse by priests, if they thought the recent allegations had harmed the overall reputation of the Catholic Church, if they thought Catholic priests were more likely then other men to sexually abuse children, and if they believed that the policy of the Catholic Church prohibiting priests from marrying contributed to the problem. Finally, respondents were asked a series of questions designed to assess their opinions of the Catholic Church's past responses to allegations of sexual misconduct and their ideas on how the Church should respond in the future. They were asked whether they agreed with the church's response of transferring a priest who had been accused of sexual abuse to another parish, whether they believed that the church should inform parishioners and/or police if a parish priest was accused of sexually abusing a child, and whether the church should be required by law to inform police or parishioners. The results of the poll were announced on the ABC television program "Nightline." Background information on respondents includes age, gender, political party, education, religion, typical attendance of religious services, and ethnicity. Catholic respondents were also asked how much they trusted their own parish priest around children.

For this data collection, Cuban and Mexican male immigrants were interviewed upon their entry into the United States in 1973-1974, with follow-up interviews in 1976 and 1979. The project sought to explore the causes and results of changes that occur following immigration by examining the complex interrelationships between the effects of what immigrants "bring with them" and the social and economic context that receives them. The first interview elicited demographic information such as marital status, number of children, education, parental information, present and prior occupations, date and community of birth, prior residency in the United States, present residency, relatives and friends in the United States, religious practices, and association membership. Respondents were also asked about their reasons for coming to the United States, plans to change residency, perceptions of discrimination in the United States, and aspirations concerning future occupations, salaries, education, and opportunities to reach their goals. Subsequent interviews expanded upon or recorded changes in these areas and also added wife's information and items on perceptions of problems in the United States, ethnicity of social relationships and neighborhood, satisfaction with living in the United States, plans to return to their homeland, languages spoken, read, and listened to, whether residence was owned or rented, and whether respondent had become a United States citizen. The study also recorded Duncan Scores, Treiman Scores, and scores on the Kahl Modernity Index, Knowledge of English Index, and Knowledge of U.S. Index.

Obsessive-compulsive disorder (OCD), which involves obsessional thoughts and compulsive actions performed in response to those thoughts, is an anxiety disorder that affects many children. An important question is whether early-onset OCD should be viewed as a special type of OCD, one that it has different characteristics than later-onset OCD. If so, individuals with early-onset OCD might respond differently to treatments. Consequently, the age of children at OCD onset was a focus of this study. Past researchers have reported that early age at onset is linked to more severe symptoms and that more males than females have the early-onset type of OCD. As such, we predicted that males would develop the disorder earlier than females and therefore experience more severe OCD symptoms. We used an online survey to recruit parents and caregivers of children with OCD from countries with large English-speaking populations. Girls and boys did not differ significantly in the severity of symptoms, nor was the severity of their symptoms predicted by the age at which their OCD symptoms first appeared. However, poorer family functioning was associated with greater OCD symptom severity. The role of family functioning in child OCD has been little studied, so future research should attend to the relation between family functioning and the development and severity of OCD symptoms in children.

The Head Start Family and Child Experiences Survey (FACES) is a major source of information on Head Start programs and the children and families they serve. Since 1997, FACES has conducted studies in a nationally representative sample of Head Start programs, but has historically not included Region XI (programs operated by federally-recognized tribes), whose programs are designed to serve predominantly American Indian and Alaska Native (AI/AN) children and families. The American Indian and Alaska Native Head Start Family and Child Experiences Survey 2015 (AI/AN FACES 2015), the first national study of Region XI AI/AN Head Start children and families, is designed to fill this information gap. The design of AI/AN FACES 2015 has been informed by members of the AI/AN FACES 2015 Workgroup which includes tribal Head Start directors, researchers with expertise working with tribal communities, Mathematica Policy Research study staff, and federal officials from the Office of Head Start, Region XI, and the Office of Planning, Research and Evaluation. Building on FACES as the foundation, members of the AI/AN FACES 2015 Workgroup have shared insights and information on the kinds of information needed about children and families served by Region XI AI/AN Head Start programs (including children's development and school readiness, parent and family demographics, health, and program engagement, and teacher, classroom, and program characteristics). Members also provided input on recruitment practices and study methods that are responsive to the unique cultural and self-governing contexts of tribal Head Start programs. Data collection with Region XI children, families, classrooms, and programs took place in the Fall of 2015 and the Spring of 2016. Twenty-one Region XI Head Start programs participated. Procedures for tribal review and approval in each of those 21 communities were followed. Information about this study has been shared broadly with tribal Head Start programs and tribal leaders via OHS tribal consultations, nationally-broadcast webinars, National Indian Head Start Directors' Association Board of Directors (NIHSDA) annual conferences, the 2016 ACF National Research Conference on Early Childhood, and the Secretary's Tribal Advisory Council (STAC) December 2014 and 2016 meetings.

Historically there has been little information about children attending Region XI Head Start programs (programs operated by federally recognized tribes); however, in 2015 the first AIAN FACES study provided a national picture of children, families, and programs in Region XI. Native voices were at the forefront of this study in the AIAN FACES 2015 Workgroup, comprised of Region XI Head Start directors, researchers, and federal officials. AIAN FACES 2019 is the second round of this national study of Region XI Head Start children and families and their experiences in Head Start programs and classrooms. The AIAN FACES 2019 study design is the same as the design for AIAN FACES 2015. AIAN FACES 2019 convened its own workgroup with a composition similar to the 2015 workgroup. The AIAN FACES 2019 Workgroup provided advice on study activities from measurement updates to data collection and dissemination. AIAN FACES 2019 sought to (1) describe the strengths and needs of all children in Region XI, (2) provide an accurate picture of all children and families who participate in Region XI (AIAN and non-AIAN), and (3) understand the cultural and linguistic experiences of Native children and families in Region XI AIAN Head Start. Data collection with Region XI children, families, classrooms, and programs took place in the fall of 2019 and the spring of 2020. In both fall and spring, the study collected data from parent surveys and teacher child reports. In fall 2019, the study conducted direct child assessments. In spring 2020, teachers, center directors, and program directors completed surveys. Twenty-two Region XI Head Start programs participated. The study followed procedures for tribal review and approval in each of those 22 communities. AIAN FACES 2019 also planned to conduct direct child assessments and classroom observations in spring 2020. Due to the COVID-19 (for coronavirus disease 2019) pandemic, AIAN FACES cancelled in-person data collection (direct child assessments and classroom observations) after the second week of March, 2020. Therefore, the study was only able to collect direct child assessment and classroom observation data in seven of its 22 programs. For more information on the spring 2020 direct child assessments and classroom observations, see the Spring 2020 Partial Sample User's Manual. Researchers may request access to the Spring 2020 Partial Sample Data File containing these partial data from direct child assessments and classroom observations as part of their application. The data are provided in a separate file for exploratory purposes only. These partial data cannot be used to develop estimates representing Region XI children as a whole.

The American Time Use Survey (ATUS) collects information on how people living in the United States spend their time. Data collected in this study measured the amount of time that people spent doing various activities in 2008, such as paid work, child care, religious activities, volunteering, and socializing. Respondents were interviewed once about how they spent their time on the previous day including where they were and whom they were with. Part 1, Respondent and Activity Summary File, contains demographic information about respondents and a summary of the total amount of time they spent doing each activity that day. Part 2, Roster File, contains information about household members and non-household children under the age of 18. Part 3, Activity File, includes additional information on activities in which respondents participated, including the location of each activity and the total time spent on secondary child care. Part 4, Who File, includes data on who was present during each activity. Part 5, ATUS-CPS 2008 File, contains demographic and occupational data on respondents and members of their household collected during their participation in the Current Population Survey (CPS). Parts 6-9 contain supplemental data files that can be used for further analysis of the data. Part 6, Case History File, contains information about the interview process. Part 7, Call History File, gives information about each call attempt. Part 8, Trips File, provides information about the number, duration, and purpose of overnight trips away from home for two or more nights in a row in a given reference month. Part 9, ATUS 2008 Replicate Weights File, contains base weights, replicate base weights, and replicate final weights for each case that was selected to be interviewed for the ATUS. The Eating and Health (EH) Module collected data to analyze (1) the relationships among time use patterns and eating patterns, nutrition, and obesity, and (2) food and nutrition assistance programs, and grocery shopping and meal preparation. The Eating and Health Module contained four files, parts 10-13. Part 10, EH Respondent File, contains information about (1) EH respondents, including variables about grocery shopping and meal preparation, food stamp participation, general health, height, and weight, and (2) household income. Part 11, EH Activity File, contains information on respondents' secondary eating and secondary drinking of beverages. Part 12, EH Child File, contains information on children (under age 19) in respondent households who ate a breakfast or lunch in the previous week that was prepared and served at a school, day care, Head Start center, or summer day program. Part 13, EH Replicate Weights File, contains the 160 replicate final weights that can be used to calculate standard errors and variances for EH Module estimates. Note that the EH Replicate Weights file contains records only for those cases that completed EH Module interviews. Demographic variables include sex, age, race, ethnicity, marital status, education level, income, employment status, occupation, citizenship status, country of origin, labor union membership of household members, and household composition.

AmeriStat is a search engine developed by the Population Reference Bureau in partnership with the Social Science Data Analysis Network (SSDAN). AmeriStat searches large data files from a range of sources, including the 2000 Census and the Census Bureau's monthly Current Population Surveys, to give the user instant summaries, in text and graphics, of the demographic characteristics of the U.S. population. AmeriStat covers 13 topics: (1) 2000 Census, (2) children, (3) education, (4) labor and employment, (5) fertility, (6) foreign-born, (7) income and poverty, (8) marriage and family, (9) migration, (10) mortality, (11) older population, (12) estimates and projections, and (13) race and ethnicity. For each of the topics, data are shown, whenever possible, for five-year data points going back to 1970. Single-year data are shown for more recent years, with special coverage of the 2000 Census. Search results also yield links to other Web sites for additional, more detailed information.

In October 2013, the Pacific Institute for Research and Evaluation (PIRE), in partnership with Big Brothers Big Sisters of Kentuckiana (BBBS-KY), was funded by the Office of Juvenile Justice and Delinquency Prevention (OJJDP) to implement a mentoring research best practices project that explored whether three types of parent/guardian level variables (psychosocial parent/family characteristics, parent engagement in the mentoring match, and parenting style) influence match quality, match length, and youth outcomes. This study was designed to describe these factors, as well as investigate how these factors impact match length, match strength, and youth program outcomes. Data to inform both objectives was collected using a longitudinal multimode approach with youth, mentors and parents in the BBBS-KY program in the metro Louisville area. In addition, data from 16 local school districts provided measures of academic performance, school attendance, and disciplinary suspensions. Data were collected at multiple time points from youth, volunteer mentors, and parents/guardians. These data included BBBS-America standard surveys (Youth Outcomes Survey, and Volunteer and Youth Strength of Relationship Surveys). PIRE supplemented the standard BBBS data collection efforts with project-specific baseline volunteer mentor survey and several formative and outcome based inserts to supplement the data that was regularly collected from youth and mentors. The PIRE and BBBS-KY teams also created a project-specific parent/guardian survey to better understand the impact of parental factors on match dynamics and youth mentoring program outcomes. Due to low literacy levels of parents/guardians, this survey was administered as a mixed-mode, audio-computer assisted interview (ACASI). Additional data sources for this study included data from (a) coding of qualitative case review notes for selected aspects of matches by BBBS-KY match support specialists, (b) academic data collected from school districts, and (c) data collected on general match characteristics (e.g., match closure status) collected by BBBS-KY as part of their standard business operations. Most measures were collected early in the match (either match formation or three months into the match) and at 12 months into the match.

The Food and Fitness Survey is part of the larger Bridging the Gap (BTG) research program, which is a research initiative funded by the Robert Wood Johnson Foundation. The primary goals of the Food and Fitness survey project were to obtain nationally representative information on school practices, and to obtain information about the association between district-level wellness policies and practices in those schools. Food and Fitness involved annual surveys of school-level respondents at elementary schools from the 2006-07 to the 2012-13 school years. This study contains data from these surveys for public and private elementary schools from the 2006-07 to the 2012-13 school years. Topics of the surveys include school characteristics, school meal options and prices, food advertisements in schools, food practices in classrooms and school functions, meal times during the day, physical education facilities and curriculum, methods of transportation to and from school, school wellness policies, school beverage guidelines, the "Nutritional Guidelines for Competitive Foods", school vending machines, and a la carte as well as school store food and beverage offerings.

Beginning with the school year 2006-07, the Child Nutrition and WIC Reauthorization Act of 2004 required school districts participating in the National School Lunch Program or other child nutrition programs to adopt and implement a wellness policy. The Healthy, Hunger-Free Kids Act of 2010 continued and strengthened this requirement. This study was intended to provide detailed insight into the contents of the congressionally-mandated district wellness policies for school years 2006-07 (first year of the mandate) through 2013-14 (last year of funding-supported data collection). The data file contains coded information about the required wellness policy components, along with other components that are known to contribute to student health and wellness: nutrition education; standards for USDA child nutrition programs and school meals; nutrition standards for competitive and other foods and beverages; physical education; physical activity; staff wellness and modelling; stakeholder involvement; messaging, marketing and promotion; evaluation; and reporting. There is a separate record in the data file for each district, grade level (elementary, middle and high school) and school year combination.

This data set contains Bridging the Gap (BTG) (school years 2006-2007 through 2012-2013) and National Wellness Policy Study (2013-2014) coded data for all state laws (statutory and administrative) that relate to areas included in the congressionally-mandated school district wellness policies. Topics include nutrition education, school meals, competitive foods, physical activity, and implementation/evaluation, as well as other topics of relevance related to physical education, communications and marketing, staff wellness, and marketing and promotion. Although the states were not required to develop laws on this topic, many do have them and many districts embed these state laws by reference in their district policies. This study was intended to provide detailed insight into the contents of state laws that overlay the congressionally-mandated district wellness policies. There is a separate record in the data file for each state, grade level (elementary, middle and high school) and school year combination.

This survey is part of a continuing series designed to monitor trends in a wide range of social attitudes in Great Britain. The British Social Attitudes Survey (BSA) is similar in purpose to the General Social Survey carried out by the National Opinion Research Center (NORC) in the United States. The BSA questionnaire had two parts, one administered by an interviewer and the other completed by the respondent. As in the past, the 1986 interview questionnaire contained a number of "core" questions covering the major topic areas of defense, the economy, labor market participation, and the welfare state. The 1986 self-enumerated questionnaire was devoted to a series of questions on a range of social, economic, political, and moral issues. Topics that received attention (by section) include: (1) newspaper readership, politics, and defense, (2) economic issues and policies, household income, economic activity, and labor market participation, (3) the welfare state and National Health Service, (4) social class and race, (5A) families and children, (5B) politics and trust, (6A) road traffic law, (6B) industry and jobs, (7A) food and health, (7B) countryside issues, (8) housing, and (9) classification items. Beginning in 1985, an international initiative funded by the Nuffield Foundation, the International Social Survey Program (ISSP), also contributed a module to the BSA. The topic of the ISSP module in this collection was family support networks. Additional demographic data gathered included age, gender, education, occupation, household income, marital status, social class, and religious and political affiliations.

This data collection effort, initiated by Dr. Donald J. West and continued by Dr. David Farrington, was undertaken to test several hypotheses about delinquency. The investigators examined socioeconomic conditions, schooling, friendship, parent-child relationships, extracurricular activities, school records, and criminal records. They also performed psychological tests to determine the causes of crime and delinquency. Information in the survey includes reports from peers, family size, child-rearing behavior, job histories, leisure habits, truancy, popularity, physical attributes, tendencies toward violence, sexual activity, and self-reported delinquency.

This poll, the last of three fielded January 2012, is a part of a continuing series of monthly surveys that solicits public opinion on a range of political and social issues. Opinions were collected on federal income taxes, the federal tax policy on capital gains, and whether respondents felt things in the United States were going in the right direction. Respondents were also queried on topics such as firearms, hedge funds, online piracy, and past presidents. Additional topics include respondents' television preferences, the Academy Awards, the Super Bowl, and Valentine's Day. Demographic information includes sex, age, race, marital status, education level, household income, religious preference, type of residential area (e.g., urban or rural), political party affiliation, political philosophy, military service, and whether respondents thought of themselves as born-again Christians.

This poll, fielded July of 2011 and the second of two, is a part of a continuing series of monthly surveys that solicits public opinion on a range of political and social issues. Respondents were asked whether they had children who had been bullied, and whether the bullying had occurred on the internet, via text message, or at school. Respondents were also asked if their children's school had a specific policy that dealt with bullying, and how effective that policy was. Multiple questions addressed the use of social networking accounts by children. Additional topics included the whether the country is on the right track, pop culture, whether Pakistan is an ally of the United States, and their knowledge of and relationship to an individual killed in the September 11, 2001 terrorist attack. Demographic variables include sex, age, race, education level, household income, religious preference, type of residential area (e.g., urban or rural), whether respondents thought of themselves as born-again Christians, marital status, employment status, number of children, number of people in the household between the ages of 18 and 29 years old, political party affiliation, political philosophy, and voter registration status.

This poll is part of a continuing series of monthly surveys that solicit public opinion on the presidency and on a range of other political and social issues. Respondents were asked about the economy and about the responsibility of the United States in the international arena in general and in Bosnia in particular. Opinions were also solicited on Hillary Clinton and her role as First Lady, the Whitewater real estate deal, and the importance of the news media in forming public opinion. The topic of religion was covered in detail, with particular attention to respondents who identified themselves as Catholic. Catholic respondents were asked whether they had said the rosary, gone to confession, attended a meeting of a Catholic organization, or prayed in private during the preceding 30 days. Further questions concerned whether the Catholic Church was in touch with the needs of Catholics, and if the respondent was in favor of letting Catholic priests get married, allowing women to be ordained as Catholic priests, and having girls assist in altar duties. Other topics covered whether people can be considered "good Catholics" if they get divorced and remarry, practice artificial birth control, or engage in homosexual relations. Additional questions asked Catholic respondents whether they thought that the Church's teaching on premarital sex, the shortage of priests and nuns, and reports of priests sexually abusing children would hurt the Church. Background information on respondents includes voter registration status, household composition, vote choice in the 1992 presidential election, political party, political orientation, education, age, sex, race, religious preference, and family income.

The 1940 Census Public Use Microdata Sample Project was assembled through a collaborative effort between the United States Bureau of the Census and the Center for Demography and Ecology at the University of Wisconsin. The collection contains a stratified 1-percent sample of households, with separate records for each household, for each "sample line" respondent, and for each person in the household. These records were encoded from microfilm copies of original handwritten enumeration schedules from the 1940 Census of Population. Geographic identification of the location of the sampled households includes Census regions and divisions, states (except Alaska and Hawaii), standard metropolitan areas (SMAs), and state economic areas (SEAs). Accompanying the data collection is a codebook that includes an abstract, descriptions of sample design, processing procedures and file structure, a data dictionary (record layout), category code lists, and a glossary. Also included is a procedural history of the 1940 Census. Each of the 20 subsamples contains three record types: household, sample line, and person. Household variables describe the location and condition of the household. The sample line records contain variables describing demographic characteristics such as nativity, marital status, number of children, veteran status, wage deductions for Social Security, and occupation. Person records also contain variables describing demographic characteristics including nativity, marital status, family membership, education, employment status, income, and occupation.

This data collection contains a stratified 1-percent sample of households, with separate records for each household, each "sample line" respondent, and each person in the household. These records were encoded from microfilm copies of original handwritten enumeration schedules from the 1950 Census of Population. Geographic identification of the location of the sampled households includes Census regions and divisions, states (except Alaska and Hawaii), Standard Metropolitan Areas (SMAs), and State Economic Areas (SEAs). The data collection was constructed from and consists of 20 independently-drawn subsamples stored in 20 discrete physical files. The 1950 Census had both a complete-count and a sample component. Individuals selected for the sample component were asked a set of additional questions. Only households with a sample line person were included in the 1950 Public Use Microdata Sample. The collection also contains records of group quarters members who were also on the Census sample line. Each household record contains variables describing the location and composition of the household. The sample line records contain variables describing demographic characteristics such as nativity, marital status, number of children, veteran status, education, income, and occupation. The person records contain demographic variables such as nativity, marital status, family membership, and occupation.

This data collection is a component of Summary Tape File 3, which consists of four sets of data containing detailed tabulations of the nation's population and housing characteristics produced from the 1980 Census. The STF 3 files contain sample data inflated to represent the total United States population. The files also contain 100-percent counts and unweighted sample counts of persons and housing units. All files in the STF 3 series are identical, containing 321 substantive data variables organized in the form of 150 "tables," as well as standard geographic identification variables. Population items tabulated for each person include demographic data and information on schooling, ethnicity, labor force status, and children, as well as details on occupation and income. Housing items include size and condition of the housing unit as well as information on value, age, water, sewage and heating, vehicles, and monthly owner costs. Each dataset provides different geographic coverage. STF 3A provides summaries for the states or state equivalents, counties or county equivalents, minor civil divisions (MCDs) or census county divisions (CCDs), places or place segments within MCD/CCDs and remainders of MCD/CCDs, census tracts or block numbering areas and block groups or, for areas that are not block numbered, enumeration districts, places, and congressional districts. There are 52 files, one for each state, the District of Columbia, and Puerto Rico. The information in the file for Puerto Rico is similar to but not identical to the data for the 50 states and the District of Columbia. Thus, this file is documented in a separate codebook. The Census Bureau's machine-readable data dictionary for STF 3 is also available through CENSUS OF POPULATION AND HOUSING, 1980 [UNITED STATES]: CENSUS SOFTWARE PACKAGE (CENSPAC) VERSION 3.2 WITH STF4 DATA DICTIONARIES (ICPSR 7789), the software package designed specifically by the Census Bureau for use with the 1980 Census data files.

This data collection is a component of Summary Tape File (STF) 3, which consists of four sets of data files containing detailed tabulations of the nation's population and housing characteristics produced from the 1980 Census. The STF 3 files contain sample data inflated to represent the total United States population. The files also contain 100-percent counts and unweighted sample counts of persons and housing units. All files in the STF 3 series are identical, containing 321 substantive data variables organized in the form of 150 "tables," as well as standard geographic identification variables. Population items tabulated for each person include demographic data and information on schooling, Spanish origin, language spoken at home and ability to speak English, labor force status in 1979, residency in 1975, number of children ever born, means of transportation to work, current occupation, industry, and 1979 details on occupation, hours worked, and income. Housing items include size and condition of the housing unit as well as information on value, age, water, sewage and heating, number of vehicles, and monthly owner costs (e.g., sum of payments for real estate taxes, property insurance, utilities, and regular mortgage payments). Selected aggregates and medians are also provided. Each dataset in STF 3 provides different geographic coverage. Summary Tape File 3B provides summaries for each 5-digit ZIP-code area within a state, and for 5-digit ZIP-code areas within states that were contained within Standard Metropolitan Statistical Areas (SMSAs), portions of SMSAs, or within counties, county portions, or county equivalents. All persons and housing units in the United States were sampled. Population and housing items include household relationship, sex, race, age, marital status, Hispanic origin, number of units at address, complete plumbing facilities, number of rooms, whether owned or rented, vacancy status, and value for noncondominiums. The Census Bureau's machine-readable data dictionary for STF 3 is also available through CENSUS OF POPULATION AND HOUSING, 1980 [UNITED STATES]: CENSUS SOFTWARE PACKAGE (CENSPAC) VERSION 3.2 WITH STF4 DATA DICTIONARIES (ICPSR 7789), the software package designed specifically by the Census Bureau for use with the 1980 Census data files.

Summary Tape File 4 consists of three sets of computer-readable data files containing highly detailed tabulations of the nation's population and housing characteristics produced from the 1980 Census. The files contain sample data inflated to represent the total United States population. The files also contain 100-percent counts and unweighted sample counts of persons and housing units. This series is comprised of STF 4A, STF 4B, and STF 4C. All three series have identical tables and format. Population items tabulated for each area include demographic data and information on schooling, ethnicity, labor force status, children, and details about occupation and income. Housing items include data on size and condition of the housing unit as well as information on value, age, water, sewage and heating, vehicles, and monthly owner costs.

Summary Tape File (STF) 4C provides summary statistics on population and housing characteristics produced from the 1980 Census. This extract of STF 4C provides data for Standard Metropolitan Statistical Areas (SMSAs), urbanized areas, and the state components of SMSAs and urbanized areas. The summary data are presented as a series of tables, one variable per table cell, which are repeated for each area. Population items tabulated for each area include age, race, sex, marital status, and Spanish origin, plus information on schooling, employment status, children, occupation, and income. Housing items include data on size and condition of the housing unit as well as information on value, age, water, sewage and heating, vehicles, and monthly owner costs.

This data collection contains tables from the 1980 Census of Population and Housing, which were tabulated for Standard Metropolitan Statistical Areas (SMSAs), tracted portions of states outside SMSAs, and the following SMSA components: counties, places with 10,000 or more inhabitants, and census tracts. The tables primarily contain sample data inflated to represent the total population, plus 100-percent counts and unweighted sample counts of persons and housing units. Tabulated population items include household relationship, sex, race, age, marital status, Spanish origin, education, nativity, citizenship, language spoken at home, ancestry, children, place of residence in 1975, veteran status, work disability status, labor force status, travel time to work, means of transportation to work, industry, occupation, class of worker, income, and poverty status. Tables of housing variables cover number of units at address, presence of complete plumbing facilities, number of rooms, tenure (whether owned or rented), vacancy status, housing unit value, contract rent, units in structure, stories in structure and presence of a passenger elevator, year structure was built, year householder moved into unit, acreage, source of water, sewage disposal, heating equipment, house heating fuel, water heating fuel, cooking fuel, kitchen facilities, number of bedrooms, number of bathrooms, telephone in housing unit, air conditioning, number of automobiles, vans, and light trucks, and selected monthly owner costs (real estate taxes, property insurance, utilities, and mortgage payments). Two series of population and housing tables, A and B, are shown for each geographic unit. The A tables are tabulated once for the total population, while the B tables are repeated for the total population and up to six different race and Spanish origin groups: (1) white, (2) Black, (3) American Indian, Eskimo and Aleut, (4) Asian and Pacific Islander, (5) other race, and (6) Spanish origin. The data for each state are contained in a separate file. Altogether, 48 states and the District of Columbia are represented in the collection.

The Center for Education and Drug Abuse Research (CEDAR) conducts research on 775 families enrolled in the Center's prospective investigations into the etiology of substance use disorder (SUD). The pro-bands are men with lifetime presence/absence of SUD consequent to use of an illicit drug who have a 10-12 year old biological son or daughter. The biological children of SUD men are assigned to the high average risk (HAR) group whereas offspring of men without SUD, having neither axis 1 disorder ("normal") nor SUD psychiatric disorder, are assigned to the low average risk (LAR) group. A second control group (Psych control) was also collected, in whom the fathers had a lifetime DSM-III-R diagnosis of any psychiatric disorder not related to substance use. The sample sizes are as follows: HAR = 344, LAR = 350, and Psych = 81. The children are currently in varying stages of follow-up evaluation conducted at ages 12-14, 16, 19, and annually thereafter until age 30. CEDAR has already shown that they can predict in 10-12 year old youth cannabis use disorder by age 22 with approximately 70 percent accuracy, thereby substantiating the paradigm, subject recruitment strategy, and measurement protocols. Multidisciplinary research is conducted on family members (father, mother, children) with the objective of elucidating the genetic, bio-behavioral, and environmental factors on development of SUD consequent to use of illegal drugs. Research protocols are organized into three thematically connected research modules (Neurogenetics, Developmental Psychopathology, and Translation) linking etiology and prevention. The research components thus align with the NIH Roadmap model such that basic science informs clinical research leading to prevention guided by an understanding of etiology. In addition to module-level research, faculty also participate in three organizational aims: (1) Devise a practical scale to quantify the transmissible liability to SUD; (2) Empirically test a bio-psychological theory of SUD etiology focusing on off-time maturation leading to psychological dysregulation predisposing to SUD; and, (3) Delineate SUD liability variants within an ontogenetic framework.

This administrative dataset provides descriptive information about the families and children served through the federal Child Care and Development Fund (CCDF). CCDF dollars are provided to states, territories, and tribes to provide assistance to low-income families receiving or transitioning from temporary public assistance, in obtaining quality child care so they can work, or depending on their state's policy, attend training or receive education. The Personal Responsibility and Work Opportunity Act of 1996 requires states and territories to collect information on all family units receiving assistance through the CCDF and to submit monthly case-level data to the Child Care Bureau. States are permitted to report case-level data for the entire population or a sample of the population, under approved sampling guidelines. These sample files were created using the data that were current as of December 12, 2003. The Summary Records file contains monthly state-level summary information including the number of families served. The Family Records file contains family-level data including single parent status of the head of household, monthly co-payment amount, date on which child care assistance began, reasons for care (e.g., employment, training/education, protective services, etc.), income used to determine eligibility, and source of income. The Child Records file contains child-level data including ethnicity, race, gender, and date of birth. The Setting Records file contains information about the type of child care setting, the total amount paid to the provider, and the total number of hours of care received by the child. The Pooling Factor file provides state- level data on the percentage of child care funds that are provided through the CCDF.

USER NOTE: This database no longer contains the most up-to-date information. Some errors and missing data from the previous years have been fixed in the most recent data release in the CCDF Policies Database Series. The most recent release is a cumulative file which includes the most accurate version of this and all past years' data. Please do not use this study's data unless you are attempting to replicate the analysis of someone who specifically used this version of the CCDF Policies Database. For any other type of analysis, please use the most recent release in the CCDF Policies Database Series. The Child Care and Development Fund (CCDF) provides federal money to States, Territories, and Tribes to provide assistance to low-income families receiving or in transition from temporary public assistance, to obtain quality child care so they can work, to attend training, or receive education. Within the broad federal parameters, States and Territories set the detailed policies. Those details determine whether a particular family will or will not be eligible for subsidies, how much the family will have to pay for the care, how families apply for and retain subsidies, the maximum amounts that child care providers will be reimbursed, and the administrative procedures that providers must follow. Thus, while CCDF is a single program from the perspective of federal law, it is in practice a different program in every State and Territory. The CCDF Policies Database project is a comprehensive, up-to-date database of inter-related sources of CCDF policy information that support the needs of a variety of audiences through (1) Analytic Data Files and (2) a Book of Tables. These are made available to researchers, administrators, and policymakers with the goal of addressing important questions concerning the effects of alternative child care subsidy policies and practices on the children and families served, specifically parental employment and self-sufficiency, the availability and quality of care, and children's development. A description of the Data Files and Book of Tables is provided below: 1. Detailed, longitudinal Analytic Data Files of CCDF policy information for all 50 States, the District of Columbia, and United States Territories that capture the policies actually in effect at a point in time, rather than proposals or legislation. They focus on the policies in place at the start of each fiscal year, but also capture changes during that fiscal year. The data are organized into 32 categories with each category of variables separated into its own dataset. The categories span five general areas of policy including: Eligibility Requirements for Families and Children (Datasets 1-5) Family Application, Terms of Authorization, and Redetermination (Datasets 6-13) Family Payments (Datasets 14-18) Policies for Providers, Including Maximum Reimbursement Rates (Datasets 19-27) Overall Administrative and Quality Information Plans (Datasets 28-32) The information in the Data Files is based primarily on the documents that caseworkers use as they work with families and providers (often termed "caseworker manuals"). The caseworker manuals generally provide much more detailed information on eligibility, family payments, and provid,er-related policies than the documents submitted by States/Territories to the federal government. The caseworker manuals also provide ongoing detail for periods in between submission dates. Each dataset contains a series of variables designed to capture the intricacies of the rules covered in the category. The variables include a mix of categorical, numeric, and text variables. Every variable has a corresponding notes field to capture additional details related to that particular variable. In addition, each category has an additional notes field to capture any information regarding the rules that is not already outlined in the category's variables. 2. The Book of Tables is available as a single dataset (Dataset 33) and it presents key aspects of the differences in CCDF funded programs across all states, territories, and tribes as of October 1, 2009. The Book of Tables includes variables that are calculated using several variables from the Data Files (Datasets 1-32). The Book of Tables summarizes a subset of the information available in the Data Files, and includes information about eligibility requirements for families; application, redetermination, priority, and waiting list policies; family co-payments; provider policies and reimbursement rates; and select administration and quality development information. In many cases, a variable in the Book of Tables will correspond to a single variable in the data file. Usually, the variable options used in the Book of Tables will match the variable options in the data file. In some cases, the wording of the variable options may have been slightly modified for the tables. The Data Files provide a more detailed set of information than what the Book of Tables provide including a wider selection of variables and policies over time. The Data Files capture the intricacies of the rules covered in the category for each state and timeframe. Each variable in any given dataset has a corresponding notes field to capture additional details related to that particular variable.

For any other type of analysis, please use the most recent release in the CCDF Policies Database Series. The Child Care and Development Fund (CCDF) provides federal money to States, Territories, and Tribes to provide assistance to low-income families receiving or in transition from temporary public assistance, to obtain quality child care so they can work, attend training, or receive education. Within the broad federal parameters, states and territories set the detailed policies. Those details determine whether a particular family will or will not be eligible for subsidies, how much the family will have to pay for the care, how families apply for and retain subsidies, the maximum amounts that child care providers will be reimbursed, and the administrative procedures that providers must follow.
