U.S. National Natality Survey, 1964-1966

Investigators: National Center for Health Statistics

The study is a collection of data for a sample of live births to married women occurring in calendar years 1964, 1965, and 1966. The survey extends, for statistical purposes, the range of items normally included on the vital records. It provides national estimates of births by characteristics not available from the vital registration system. It also serves as a basis for evaluating the quality of information reported on the vital records. Each data record is composed of information obtained from the birth certificate, and from questionnaires sent to the mother, the physician who delivered the baby, and the medical facility where the baby was born. The survey gathered information on pregnancy history, expectations of having more children, household composition, income, whether this was a first or later marriage, date of first marriage and date of this marriage, whether mother was employed and when during her pregnancy she stopped working, education, and health insurance. One out of 1,000 births were originally selected. This data file contains only the subsample of married mothers. Data were collected primarily by mail from addresses given on the birth certificates. The response rate was 89 percent. The total sample size is 10,395 cases. Weights may be used to reflect U.S. estimates of infant births during the study period.

U.S. National Study of High School and Beyond, Selected Variables: A Longitudinal Study of Female Sophomores, 1980-1982

Investigators: Peter Morrison, Linda Waite, and Allan Abrahamse

This is the second of two National Longitudinal Studies (NLS). The first, NLS-72, began with over 22,000 high school seniors in the spring of 1972. The second study began with a 1980 collection of base year data on individual and family background, high school experiences, work experiences, plans for the future, and cognitive ability and achievement from high school seniors and sophomores. The first follow-up was conducted in the spring of 1982, and a second follow-up was conducted in 1984. The current Data Set was designed to build on the NLS-72 by replicating selected 1972 study questionnaire and cognitive test items as well as expanding the data to include a broader range of lifecycle factors, such as family-formation behavior and social participation. Over 30,000 sophomores enrolled in 1,015 public and private high schools across the country participated in the Base Year survey, with questionnaires administered at schools or appropriate off-campus locations. The 1982 follow-up sample consisted of approximately 30,000 1980 sophomores, with different questionnaires for those who had dropped out of school and those who remained enrolled in school. The DAAPPP file is an extract designed by Peter Morrison and his colleagues at the Rand Corporation. The cases were limited to female high school sophomores who were not mothers at the time of the 1980 baseline survey. In addition to the approximately 100 variables obtained directly from the High School and Beyond Data Set, the investigators computed approximately twenty scale score and indicator variables.

U.S. National Survey of Teens Seeking Abortion Services, 1979-1980

Investigators: Aida Torres

The goal of the study was to investigate to what extent parents of unmarried teenagers 17 and younger are informed that their daughters are attending an abortion facility, how parents are informed, and how notification requirements would affect the behavior of those teenagers whose parents do not know. The study also assessed parent-daughter communication regarding contraception and abortion, in addition to contraceptive acquisition, use, and demographic information. Conducted between October 1979 and March 1980, the survey consisted of self-administered questionnaires distributed to all teenage patients in 52 abortion clinics, yielding a final sample of 1,172 (95% of abortion patients).

Welfare, Children, and Families: A Three City Study (Boston, Chicagand San Antonio), Wave 3, February 2005 - January 2006

Investigators: Andrew J. Cherlin, Ronald Angel, Linda Burton, P. Lindsay Chase-Lansdale, Robert Moffitt, and William Julius Wilson

The Welfare, Children and Families Study is a longitudinal study of children and their caregivers in low income families that were living in low-income neighborhoods in three cities during wave 1 of the study (1999). The purpose of the study is to investigate the consequences of policy changes resulting from the Personal Responsibility and Work Opportunity Reconciliation Act of 1996 (PRWORA). The survey was designed to provide information on the health and cognitive, behavioral, and emotional development of children and on their primary caregivers' labor force behavior, welfare experiences, family lives, use of social service, health, and well-being.

Welfare, Children, and Families: A Three City Study (Boston, Chicago, and San Antonio) Embedded Developmental Study, Wave 1, 1999

Investigators: Andrew J. Cherlin, Ronald Angel, Linda Burton, P. Lindsay Chase-Lansdale, Robert Moffitt, and William Julius Wilson

Welfare, Children and Families: A Three City Study is a longitudinal study of children and their caregivers in low-income families that were living in low-income neighborhoods in three cities in 1999. The purpose of the study is to investigate the consequences of policy changes resulting from the Personal Responsibility and Work Opportunity Reconciliation Act of 1996 (PRWORA). The survey was designed to provide information on the health and cognitive, behavioral, and emotional development of children and on their primary caregivers' labor force behavior, welfare experiences, family lives, use of social service, health, and well-being. The Embedded Developmental Study (EDS) was developed to gain a more detailed and valid picture of the environments and processes that affect children during early childhood that cannot be obtained through standard survey instruments. The EDS was focused on preschoolers because children in this age range embark upon developmental paths that, in turn, drive later intellectual, social and physical growth. Mothers also face challenges during this period in providing appropriate warmth, limit setting, and learning opportunities, as well as in meeting the great time demands of caring for preschool children and finding appropriate alternate care. The survey gathered detailed, process-oriented measures that provide information not easily collected in standard surveys. The EDS contains three components: (1) an additional home visit with mother and child, which includes videotaped tasks for the child and the mother-child together, as well as an additional mother interview; (2) a visit to the child's primary care provider (other than the mother), which includes observational ratings of the care and an interview with the childcare provider; and (3) an interview with the child's biological father. The EDS was undertaken with nearly all children ages two to four in the survey. It mirrored the main survey in its timeline; with all portions of the EDS completed while the main survey was conducted in the field.

Welfare, Children, and Families: A Three City Study (Boston, Chicago, and San Antonio) Embedded Developmental Study, Wave 2, 2000-01

Investigators: Andrew J. Cherlin, Ronald Angel, Linda Burton, P. Lindsay Chase-Lansdale, Robert Moffitt, and William Julius Wilson

Welfare, Children and Families: A Three-City Study is an ongoing research project in Boston, Chicago, and San Antonio to monitor the consequences of welfare reform for the well-being of children and families. The Wave 2 Embedded Developmental Study (EDS), which is a part of the longitudinal follow-up, includes interviews of a subset of children 3-6 years of age and their caregivers. It consists of videotaped assessments of children's behaviors, caregiver-child interactions, and observations of childcare settings. The interviews were conducted between October 2000 and June 2001 in Boston, Chicago, and San Antonio. The purpose of the study is to investigate the consequences of policy changes resulting from the Personal Responsibility and Work Opportunity Reconciliation Act of 1996 (PRWORA). The survey was designed to provide information on the health and cognitive, behavioral, and emotional development of children and on their mothers' labor force behavior, welfare experiences, family lives, use of social service, health, and well-being. The Embedded Developmental Study (EDS) was developed to gain a more detailed and in-depth picture of the environments and processes that affect children during early childhood than can be obtained through standard survey instruments. Detailed, process-oriented measures that provide information not easily collected in standard surveys were gathered. Wave 1 of the EDS contained three components: (1) an additional home visit with mother and child, which included videotaped tasks for the child and the mother-child together, as well as an additional mother interview; (2) a visit to the child's primary care provider (other than the mother), which included observational ratings of the care and an interview with the childcare provider; and (3) an interview with the child's biological father. In wave 2, however, only the mother and childcare provider interviews and observations were conducted. In addition, the "mother" interviews were conducted with the focal child's primary caregiver; separated caregivers from the main survey were not included in the Wave 2 EDS sample.

Youth Risk Behavior Survey, 1992

Investigators: National Center for Health Statistics

The 1992 Youth Risk Behavior Survey (YRBS) was conducted as a followback to the National Center for Health Statistics (NCHS) 1992 National Health Interview Survey (NHIS). The YRBS was sponsored by the Division of Adolescent and School Health, National Center for Chronic Disease Prevention and Health Promotion, Centers for Disease Control and Prevention. This survey is part of a larger research project, the Youth Risk Behavior Surveillance System, which was developed to monitor the major risk behaviors of American youth. The 1992 YRBS interview focused on selected types of health behaviors among youth that could lead to a greater risk for morbidity and mortality. The following substantive areas were covered in the interview: injury risks, including physical fights and weapon use; cigarette, tobacco, or snuff use; alcohol and illegal drug use; AIDS/HIV education; drug use risks; diet and nutrition; physical activities; stays away from home; and sexual intercourse. Data collection began in April 1992, approximately two months after the original NHIS interview, and continued through March 1993. A sample of children 12 to 21 years of age was drawn from the families who were interviewed for the 1992 NHIS. Within each family, one child who was attending school and up to two children not in school or whose in-school status was unknown were selected for the YRBS sample. Of the 13,789 youth identified in this manner, YRBS interviews were completed for 10,645 children. The final survey response rate was 77.2%.
