One component of the PHDCN was the Longitudinal Cohort Study, which was a series of coordinated longitudinal studies that followed over 6,000 randomly selected children, adolescents, and young adults, and their primary caregivers over time to examine the changing circumstances of their lives, as well as the personal characteristics, that might lead them toward or away from a variety of antisocial behaviors. Numerous measures were administered to respondents to gauge various aspects of human development, including individual differences, as well as family, peer, and school influences. One such measure was the Children and First Pregnancy instrument. It was administered to subjects in Cohorts 15 and 18 and collected information related to the number of children the subject had, as well as information regarding the subject's first pregnancy. 2007-02-06 survey data 13683 10.3886/ICPSR13683.v1 Chicago Illinois United States 2000--2002 ICPSR metadata records are licensed under a Creative Commons Attribution-Noncommercial 3.0 United States License (http://creativecommons.org/licenses/by-nc/3.0/us/).
