The Children & Young Adults of the NLSY79 data focus on the development and achievement of the children of the mothers in the NLSY79. Sponsored by the U.S. Department of Labor, with support from NICHD, the NLSY79 Child & Young Adult (Child-YA) dataset is an outgrowth of the National Longitudinal Surveys of Youth/79 Cohort. Started in 1986 and repeated biennially, the NLSY79 Child-YA uses mother report and direct assessment to gauge the children’s cognitive ability, temperament, motor and social development, behavior problems, perceived self-competence, and home environment. Linked with the child assessment information is an extensive series of questions addressed to the mothers of the children about pre- and post-natal care and the health of their children. Since 1988, children 10 and older have reported on: child-parent interaction, family decision-making, school attitudes, work activities, peer relationships, attitudes, religion, substance use, and sexual activity. Information on the children’s school characteristics, policies, student performance, and experiences was gathered between 1994 and 1996. The 1994 survey round replaced, for children 15 and older, the child assessment series with an hour-long CAPI interview of these Young Adults on schooling, employment, training, family experiences, health and attitudes. The NLSY79 Young Adult component also includes self-report on substance use, sexual activity, non-normative behavior, computer use, and pro-social activities. The Child/YA sample ranges in age from birth to late twenties as of the current survey. The current Child-Young Adult file contains 1986-2002 assessment scores, all questionnaire items, and a number of constructed variables related to the family background, fertility, pregnancy history, childcare practices, and work experience of the mothers. Young Adult questionnaire information from 1994-2002 is accompanied by a set of created variables for each round. Any item from the complete record of the main NLSY79 (mother) file can be linked by respondent ID to the child and young adult files. The 2004 survey is currently in the field. The Center for Human Resource Research (CHRR) at Ohio State University issues the maternal and child data and documentation at nominal cost on CD-ROM. Data and documentation are also available on-line at http://www.bls.gov/nls/nlsorder.htm. Topical research bibliographies and reports are available at no charge.
