This data collection is comprised of data from the 2006 Annual Social and Economic Supplement (ASEC), and is a part of the Current Population Survey (CPS) Series. The Census Bureau conducts the ASEC (known as the Annual Demographic File prior to 2003) over a three-month period, in February, March, and April, with most of the data collected in the month of March. The ASEC uses two sets of survey questions, the basic CPS and a set of supplemental questions.

The CPS, administered monthly, is a labor force survey providing current estimates of the economic status and activities of the population of the United States. Specifically, the CPS provides 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.

In addition to the basic CPS questions, respondents were asked questions from the ASEC, which provides supplemental data on poverty, geographic mobility/migration, and work experience. Comprehensive work experience information was given on the employment status, occupation, and industry of persons aged 15 and over. Additional data for persons aged 15 and older were available concerning weeks worked and hours per week worked, reason not working full time, total income and supplemental income components. Additional data are included that cover training and assistance received under welfare reform programs such as job readiness training, child care services, or job skill training. Data covering nine noncash income sources: food stamps, school lunch program, employer-provided group health insurance plan, employer-provided pension plan, personal health insurance, Medicaid, Medicare, CHAMPUS or military health care, and energy assistance are also included.

Demographic variables include age, sex, race, Hispanic origin, marital status, veteran status, educational attainment, occupation, and income. Data on employment and income refer to the previous calendar year, although demographic data refer to the time of the survey.

The original ASEC data provided by the Census Bureau are distributed in a hierarchical file structure, with three record types present: Household, Family, and Person. The ASEC is designed to be a multistage stratified sample of housing units, where the hierarchical file structure can be thought of as a person within a family within a household unit. Here the main unit of analysis is the household unit. For ease of analysis at the person-level, ICPSR created a rectangular file structure that contains a record for every person with the respective Household and Family variables prepended to the Person variables. Part 1 contains the rectangular data file and Part 2 contains the original hierarchical data file.

This data collection is comprised of responses from two sets of survey questionnaires, the basic Current Population Survey (CPS) and a survey on the topic of food security in the United States, which was administered as a supplement to the April 2001 CPS questionnaire.

The CPS, administered monthly, is a labor force survey providing current estimates of the economic status and activities of the population of the United States. Specifically, the CPS provides 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 survey.

The supplement was intended to research the full range of severity of food insecurity as experienced in United States households. The food security questions were asked of all interviewed households, as appropriate. Respondents were queried on how much the household spent for food, their use of federal and community food assistance programs, whether they were able to afford enough food, food sufficiency, and ways of coping with not having enough food.

Demographic variables include age, sex, race, Hispanic origin, marital status, veteran status, educational attainment, 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 on the topic of Internet and Computer Use in the United States, which was administered as a supplement to the August 2000 CPS.

The CPS, administered monthly, is a labor force survey providing current estimates of the economic status and activities of the population of the United States, for the week prior to the survey. Specifically, the CPS provides 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.

The August 2000 supplement survey queried respondents on whether there was a personal computer and/or laptop in the household, how many computers or laptops were in the household, if anyone in the household used the Internet, who was the Internet service provider, how the Internet was accessed (i.e., dial-up, DSL, or cable modem), and where the Internet was regularly accessed (e.g, from home, work, community center, library, or religious facility). Other Internet specific questions included concerns about providing personal information over the Internet, if household members used the Internet to access e-mail, news, weather, play games, take on-line courses, shop, pay bills, look for a job, or search for information about products and services (like health, government, or financial services).

Demographic variables include age, sex, race, Hispanic origin, marital status, veteran status, educational attainment, occupation, and income.

This data collection is comprised of responses from two sets of survey questionnaires, the basic Current Population Survey (CPS) and a biennial survey on the topic of veterans in the United States, which was administered as a supplement to the August 2001 CPS questionnaire.

All veterans aged 18 or older received questions from the Veterans Supplement, which provides estimates on the demographic and labor force characteristics of veterans who have a service-connected disability in comparison to all other veterans. The data also made distinctions between Gulf War era veterans and Vietnam theater veterans; the latter being veterans who served in Vietnam, Laos, or Cambodia. Estimates were also provided on the number of veterans with or without a service-connected disability and their labor force participation rate, occupational distributions, unemployment rates, periods of military service, and use of certain educational and job training programs. The Veterans Supplement portion of the study was designed to be a self-response survey and general interviewers were instructed to make up to two personal or telephone callbacks before accepting a proxy interview.

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.

The supplement was intended to research the full range of severity of food insecurity as experienced in United States households. Food Security supplement items were used by the supplement sponsor to produce a scaled measure of food insecurity. Therefore, responses to individual items should not be used as meaningful measures of food insufficiency, food insecurity, or hunger. Measures that combine information from multiple items (HRFS12M1 and following) are generally considered to be more reliable measures of food security and food insecurity. The food security questions were asked of all interviewed households, as appropriate. Respondents were queried on how much the household spent for food, their use of federal and community food assistance programs, food sufficiency, and ways of coping with not having enough food.

Demographic variables include age, sex, race, Hispanic origin, marital status, veteran status, educational attainment, 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.

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 2003 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 2003 (ICPSR 4527) and November 2003 (ICPSR 4528). These three supplements comprise the 2003 wave of TUS data.

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 February 2003 supplement items.

The TUS consisted of items PEA1 through PEK5. 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 PEJ1a -PEJ2a).

In addition to these smoking status and other tobacco use 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 where purchased

• Medical and dental advice to quit smoking

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

• Workplace smoking policies and smoking rules in the home

• Attitudes toward smoking in public places

Another generally unique feature to the 2003 TUS-CPS was the administration of questions to former smokers on their previous level of addiction, products/resources/methods used to quit smoking, and advice from health professionals. This feature enables comparisons between characteristics of former smokers (or successful quitters) and current smokers attempting to quit.

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 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 January 2007 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 August 2006 (ICPSR 24782). These three supplements comprise the 2006-2007 waves of TUS data.

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 18 years and older who had completed the basic CPS core items were eligible for the January 2007 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 (but remained for the May and August 2006 waves).

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 on the topic of veterans in the United States, which was administered as a supplement to the July 2010 CPS questionnaire. The sponsor of the biennial supplement survey were the Department of Veterans Affairs (VA), formerly the Veterans Administration, and the Department of Labor.

The CPS, administered monthly, is a labor force survey providing current estimates of the economic status and activities of the population of the United States. Specifically, the CPS provides 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 survey.

All veterans aged 17 or older received questions from the Veterans Supplement, which provides estimates on the demographic and labor force characteristics of veterans who have a service-connected disability in comparison to all other veterans. The data also made distinctions between Gulf War era veterans and Vietnam theater veterans; the latter being veterans who served in Vietnam, Laos, or Cambodia. Estimates were also provided on the number of veterans with or without a service-connected disability and their labor force participation rate, occupational distributions, unemployment rates, periods of military service, and use of certain educational and job training programs. The Veterans Supplement portion of the study was designed to be a self-response survey and general interviewers were instructed to make up to two personal or telephone callbacks before accepting a proxy interview.

Demographic variables include age, sex, race, Hispanic origin, marital status, veteran status, educational attainment, 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 on the topic of food security in the United States, which was administered as a supplement to the September 2000 CPS questionnaire.

The CPS, administered monthly, is a labor force survey providing current estimates of the economic status and activities of the population of the United States. Specifically, the CPS provides 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 survey.

The supplement was intended to research the full range of severity of food insecurity as experienced in United States households. The food security questions were asked of all interviewed households, as appropriate. Respondents were queried on how much the household spent for food, their use of federal and community food assistance programs, whether they were able to afford enough food, food sufficiency, and ways of coping with not having enough food.

Demographic variables include age, sex, race, Hispanic origin, marital status, veteran status, educational attainment, occupation, and income.

This longitudinal data collection supplies information on the educational, vocational, and personal development of young people who were high school seniors in 1972 and examines the kinds of factors -- personal, familial, social, institutional, and cultural -- that may affect that development. The collection provides a broad spectrum of information on each student and covers areas such as ability, socioeconomic status, home background, community environment, ethnicity, significant others, current activity at time of survey, educational attainment, school experiences, school performance, work status, work performance and satisfaction, goal orientations, marriage and the family, and military experience.

Data collected in the base-year (1972) focus on factors relating to the student's personal/family background, education and work experiences, plans, aspirations, attitudes, and opinions. The first follow-up, which was conducted in 1973, offers information on the respondent's activity state (education, work, etc.), socioeconomic status, work and educational experience since leaving high school, future plans, and expectations. The second follow-up (1974) probes respondents on similar measures but is augmented by additional variables pertaining to work and education. The third follow-up (1976) contains additional items on graduate school application and entry, job supervision, sex roles, sex and race biases, and a subjective rating of high school experiences. The fourth follow-up (1979) offers data similar to the other follow-ups but includes some variables that were modified to elicit unique information. For the fifth follow-up, the sample members averaged 32 years of age and had been out of high school for 14 years. In addition to covering the same subject areas as the previous surveys, this follow-up includes additional questions on marital history, divorce, child support, and economic relationships in modern families.

Part 1 of this collection contains base-year data as well as data collected during four subsequent follow-ups undertaken in 1973, 1974, 1976, and 1979, while Part 11 contains fifth follow-up data for 1986. Part 2, the School File, contains information obtained from the respondent's high school and also from high school counselors. Data are available on school organization and enrollment, course offerings, special services and programs, library and other resources, time scheduling, and grading systems. Counselor information is supplied on work loads, counseling practices and facilities, experience with student financial aid programs, age, ethnicity, training, and experience. A supplementary School District Census File, Part 3, contains 1970 Census data tabulated by school district boundaries. In addition, the collection includes a FICE Code File and a CEEB Institutional Data Base File that can be used in conjunction with the student file to supply contextual information about respondents' colleges. The Institutional Data Base File offers data for colleges and universities on items such as enrollment, income and revenues, expenses, tuition and fees, and median student scores on standardized tests. Parts 7, 8, 9 and 10 contain transcript data from each postsecondary institution reported by sample members in the first through fourth follow-up surveys. Data are available for several types of postsecondary institutions, ranging from short-term vocational or occupational programs through major universities with graduate programs and professional schools. Data in these four rectangular files -- Student, Transcript, Term, and Course Files -- are organized to be used in combination hierarchically. Information is available on terms of attendance, fields of study, specific courses taken, and grades and credits earned. The Fifth Follow-Up Teaching Supplement (Parts 12) surveyed those members of the original 1972 sample who had obtained teaching certificates and/or who had teaching experience. Respondents were asked questions about their qualifications, experience, and attitudes toward teaching.
