This data collection is comprised of responses from two sets of survey questionnaires, the basic Current Population Survey (CPS) and a survey administered as a supplement to the August 2006 basic CPS questionnaire on the topic of tobacco use in the United States. The Tobacco Use Supplement (TUS), sponsored by the National Cancer Institute and the Centers for Disease Control and Prevention, was also administered in May 2006 (ICPSR 24781) and January 2007 (ICPSR 24783). These three supplements comprise the 2006-2007 waves of TUS data.

The basic CPS, administered monthly, collects labor force data about the civilian noninstitutional population living in the United States. Moreover, the CPS provides current estimates of the economic status and activities of this population which includes estimates of total employment (both farm and nonfarm), nonfarm self-employed persons, domestics, and unpaid helpers in nonfarm family enterprises, wage and salaried employees, and estimates of total unemployment. Data from the CPS are provided for the week prior to the administration of the survey.

The TUS, like most CPS supplements, was designed to be a proxy response supplement, meaning a single respondent could provide answers for all eligible household members, provided the respondent was a household member 15 years of age or older. Unique to the TUS design were also a set of self-respondent supplement questions. All household members age 15 years and older who had completed the basic CPS core items were eligible for the August 2006 supplement items. Beginning in August 2006, 15-17 year old respondents were phased out of the TUS and they were entirely omitted from the January 2007 sample due to Census Bureau budget constraints.

The TUS consisted of items PEA1 through SINTTP. Self-respondents were eligible for the entire supplement, whereas proxy respondents were only eligible for certain items. Information was collected from proxies on topics such as smoking status (items PEA1-PEA3) and the use of other tobacco-related products, such as pipes, cigars, chewing tobacco, and snuff (items PEAJ1A1-PEAJ1A4 and PEJ2A1-PEJSA4).

In addition to these smoking and other tobacco use status questions, self-respondents were queried on the following topics depending on their smoking/tobacco use status (i.e., every day, some days, or former cigarette smokers and/or users of other non-cigarette tobacco products):

• Smoking history

• Current cigarette smoking prevalence and consumption

• Type of cigarettes smoked

• Price of last pack/carton of cigarettes purchased and state of purchase

• Medical and dental advice to quit smoking

• Attempts and intentions to quit smoking cigarettes and/or other forms of tobacco use

• Awareness of 1-800-QUIT-NOW

• Workplace smoking policies and smoking rules in the home

• Attitudes toward smoking in public places

Another generally unique feature to the 2006-2007 TUS-CPS was the administration of questions to former smokers on their previous level of addiction, use of quitlines, and advice from health professionals. This feature enables comparisons between characteristics of former smokers (or successful quitters) and current smokers attempting to quit.

Demographic information collected include age, sex, race, Hispanic origin, marital status, veteran status, educational attainment, family relationship, occupation, and income.

This data collection is comprised of responses from two sets of survey questionnaires, the basic Current Population Survey (CPS) and a survey administered as a supplement to the February 2002 questionnaire on the topic of tobacco use in the United States. The Tobacco Use Supplement (TUS), sponsored by the National Cancer Institute and the Centers for Disease Control and Prevention, was also administered in June 2001 (ICPSR 4043) and November 2001 (ICPSR 4044). These three supplements comprise the 2001-2002 waves of TUS data.

The basic CPS, administered monthly, collects labor force data about the civilian noninstitutional population living in the United States. Moreover, the CPS provides current estimates of the economic status and activities of this population which includes estimates of total employment (both farm and nonfarm), nonfarm self-employed persons, domestics, and unpaid helpers in nonfarm family enterprises, wage and salaried employees, and estimates of total unemployment. Data from the CPS are provided for the week prior to the administration of the survey.

All household members age 15 years and older who had completed the basic CPS monthly items were eligible for the TUS, which consisted of items PES32 through PES77. The TUS was mainly designed to be a proxy response survey, meaning a single respondent could provide answers for all eligible household members. Unique to the TUS design were also a set of self-respondent questions. Self-respondents were eligible for the entire supplement, whereas proxy respondents were only eligible for questions on the topics of smoking status (items PES32-PES34) and the use of other tobacco products; for example, pipes, cigars, chewing tobacco, and snuff (items PES62A-PES63B).

Additionally, self-respondents were asked various questions depending on their smoking status -- former, everyday, or occasional (items PES36-PES46 and PES55-PES61). Current everyday and occasional smokers were then asked whether the medical community had advised them to quit smoking or if they were planning to quit in the near future (items PES47-PES54). Self-respondents were further queried on smoking policies in their work place (items PES67-PES71), smoking rules in the home (item PES73) and questions on opinions about smoking (items PES72, PES75-PES77).

Administrative information was collected on who the proxy respondents were, the language in which the interview was conducted, and the survey method (telephone vs. personal-visit interviews; Computer Assisted Telephone Interviewing (CATI) vs. Computer Assisted Personal Interviewing (CAPI)). Demographic information collected includes age, sex, race, Hispanic origin, marital status, veteran status, educational attainment, family relationship, occupation, and income.

The Current Population Survey Tobacco Use Supplement data collection from January 2015 is comprised of responses from two sets of survey questionnaires, the basic Current Population Survey (CPS) and a Tobacco Use Supplement (TUS) survey. The TUS 2014-2015 Wave consists of three collections: July 2014, January 2015, and May 2015.

The CPS, administered monthly, is the source of the official government statistics on employment and unemployment. From time to time, additional questions are included on health, education, and previous work experience. The Tobacco Use Supplement to the CPS is a National Cancer Institute sponsored survey of tobacco use that has been administered as part of the US Census Bureau's CPS approximately every 3-4 years since 1992-1993.

Similar to other CPS supplements, the Tobacco Use Supplement was designed for both proxy and self-respondents. All CPS household members age 18 and older who completed CPS core items in January 2015 were eligible for the supplement items. A new feature for the 2014-2015 cycle included random selection of self-interviewed respondents in larger households to reduce respondent burden. If the household had only 1 supplement eligible member then that person was selected for self-interview. If the household had only 2 supplement eligible members, then both of them were selected for self-interview. If the household had 3 or 4 supplement eligible members, then 2 of them were randomly selected for self-interview and the remaining were interviewed by proxy. If the household had more than 4 supplement eligible members, then 3 of them were randomly selected for self-interview and the rest of the eligible respondents were interviewed by proxy.

Those selected for self-interview were eligible for the entire supplement, whereas proxy respondents were only eligible for an abbreviated interview. Occasionally, those persons to be interviewed by proxy, if available for self- interview, were interviewed directly but asked the abbreviated proxy path questions.

Both proxy and self-respondents were asked about their smoking status and the use of other tobacco products. For self-respondents only, different questions were asked depending on their tobacco use status: for former/current smokers, questions were asked about type of cigarettes smoked, measures of addiction, attempts to quit smoking, methods and treatments used to quit smoking, and if they were planning to quit in the future. All self-respondents were asked about smoking policy at their work place and their attitudes towards smoking in different locations.

Demographic information within this collection includes age, sex, race, Hispanic origin, marital status, veteran status, immigration status, educational background, employment status, occupation, and income.

The overall purpose of this study was to examine the influence of variations in early childcare histories on the psychological development of infants and toddlers from a variety of family backgrounds. This general objective was addressed through a prospective, longitudinal study of the experiences of 1,364 children and their families, which took into account the complex interactions among child characteristics and those of the human and physical environments in which the children were reared.

The specific research aims were as follows:

• Examining the relationship between infants' childcare arrangements (defined in terms of hours, type, quality, and stability of care and the age at which the child entered care) and children's concurrent and long-term development. Specifically, the study investigated the association between children's experiences in childcare and their social, emotional, language, and cognitive development. The social-emotional assessments included measures of attachment, independence, compliance, behavior problems, prosocial and antisocial behavior, and general competence in interacting with peers. Cognitive variables include general developmental level and problem solving skills. Language assessments incorporated measures of children's expressive and receptive communicative competence.

• Examining whether the social ecology of the home moderates the effects of childcare, i.e., whether children from different home environments are differentially affected by similar childcare experiences. The study examined the moderating effects of parents' values and attitudes, psychological adjustment and mental health, stress and social support, child-rearing practices, time use, interactions with the child, the marital relationship, and family demographics.

• Examining whether individual differences among children moderate the effects of infant care on child development. The study examined the moderating effects of such child characteristics as age, sex, health, birth order, and temperament.

• Identify demographic and family characteristics associated with families' childcare decisions. The study examined whether specific childcare arrangements are related to the parents' social class, marital status, psychological adjustment and personality, child-rearing values and attitudes, parenting practices, stress, social support, marital relationship, and the availability of childcare in the community.

• Provide a natural history of infant care in the 1990s, and help establish a baseline of data pertaining to the kinds of care being used by families. Whereas other national databases, such as those provided by the United States Census Bureau, provide static estimates of the number of children in different types of childcare, this network study supplements that knowledge with longitudinal data on successive enrollments into day care at various ages, patterns of arrangements used concurrently and over time, and the stability of arrangements during the first three years of life. One of the most valuable aspects of the collaborative study is the opportunity it provides to obtain a more complete and accurate picture of patterns of infant care used by families today. Census surveys use only gross categories of care (e.g., center vs. in-home). In this study, more fine-grained information regarding the types of centers and home-care facilities was gathered.

• Examine the consequences for families of maternal employment and childcare choices. Family relationships, parental mental health, family stress, and so on, are not just inputs to child development or moderators of childcare effects, they are also outcomes. High-quality childcare may alleviate family stress and enhance parental adjustment. Low-quality childcare may add to the stress parents experience. Although the main focus in the study was on the effect of childcare on the child, the study also examined the effect of childcare on the family.

• Identify demographic characteristics of childcare associated with childcare quality. Of interest to policy makers is another aspect of the study, the investigation of those regulatory characteristics that predict care of higher quality. These characteristics included the level and type of caregiver training, the size of the childcare group, the auspices of the childcare program (public/private, profit/nonprofit, independent/chain, employer-sponsored/church-based), whether the facility was licensed or unlicensed, the level of payment and fees, and whether the caregiver was a relative of the family.

309 data files were compiled for this study and are organized into 3 main groups:

1. Analytical Data Sets (ADS) -- The raw data were examined and composites defined by small groups of individual principal investigators according to the demographic, family, childcare, and child outcome content of the data. The psychometric and distributional qualities of the variables, along with site differences, were examined. A set of variables that were psychometrically and distributionally acceptable to be used in analytic analyses was designed to test the study hypotheses. These data files comprise Parts 1-42 of the study data material.

2. Supplemental Data Sets -- New and revised analysis variables as well as across-time mean scores and primary composites were produced as a supplement to the original Analytical Datasets. These data files comprise Parts 43-55 of the study data material.

3. Raw Data Sets -- The raw data were made available and comprise Parts 56-309 of the study data material.

A three-day summer training workshop on the SECCYD was put on by NICHD at the Inter-University Consortium for Political and Social Research in Ann Arbor, Michigan in 2010. The binder from that workshop, which includes the Powerpoint slides used during presentations, are freely available to the public as part of the study documentation.

4. Raw Data Sets -- The raw data were made available and comprise Parts 31-158 of the study data material.

Included in this phase of the study are the output of several third-party software programs that were used during Phases II, III and IV to collect data for specific tasks or activities. These programs produced one output data file per subject, which were combined to produce some of the raw data files for those studies. The original program output is included as expanded documentation in this phase of the study.

This research investigated the relationship between ascribed characteristics, family resources, personal circumstances, and public policies as these affect the transition to adulthood. The transition to adulthood has been extensively studied during the last four decades using a variety of well-established approaches and methods. Changes in the structure and pace of youth-to-adult transitions have been extensively documented, along with the increasingly complex lives young people lead as they negotiate the transition to adulthood. Relatively less attention has been devoted to the factors leading to these changes, and a variety of public policies related to state economic development efforts, education, and financial support for higher education have yet to be examined in any detail. This project built on the principal investigators' prior work on life course transitions and state economic and political contexts to estimate behavioral models of the late 20th and early 21st century transition to adulthood.

Specifically, this research:

1. Defines and describes the successful transition to adulthood in terms of human capital accumulation, attainment of economic security, and partnership and life satisfaction.
2. Identifies group and individual disparities in successful transitions, defined by ascribed characteristics, family resources, and personal circumstances.
3. Measures the impact of the social and economic environments where these transitions occur and the effects of state structures and policies on the successful transition to adulthood, specifically examining whether the impact of these state policies differs by race/ethnicity, immigrant status, and disability status.

The analysis used discrete hazard modeling and hierarchical generalized linear modeling (HGLM) to build a general model of the transition to adulthood on a wide variety of dimensions (from educational attainment to stable employment in a full-time job, employment in a job with health insurance, to independent residence and life satisfaction) and examined systematic changes in the process leading to adulthood across cohorts and across race/ethnic, immigrant, and disability groups.
