          <abstract>The Project on Human Development in Chicago Neighborhoods
(PHDCN) was a large-scale, interdisciplinary study of how families,
schools, and neighborhoods affect child and adolescent development.
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. The data
files in this study contain basic demographic information, as well as
information relevant to race/ethnicity and family acculturation.</abstract>
 			
           <abstract><p><hi>Project on Human Development in Chicago

 <p>The Project on Human Development in Chicago Neighborhoods (PHDCN)
 was a large-scale, interdisciplinary study of how families, schools,
 and neighborhoods affect child and adolescent development. It was
 designed to advance the understanding of the developmental pathways of
 both positive and negative human social behaviors. In particular, the
 project examined the causes and pathways of juvenile delinquency,
 adult crime, substance abuse, and violence. At the same time, the
 project provided a detailed look at the environments in which these
 social behaviors took place by collecting substantial amounts of data
 about urban Chicago, including its people, institutions, and
 resources.</p>
 <p><hi>Longitudinal Cohort Study</hi></p>
 <p>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. The age 
 cohorts include birth (0), 3, 6, 9, 12, 15, and 18 years. Numerous 
 measures were administered to respondents to gauge various aspects of 
 human development, including individual differences, as well as family, 
 peer, and school influences.</p>
 <p><hi>Demographic File</hi></p>
 <p>The data in this collection are from Wave 1 of the Longitudinal
 Cohort Study, which was administered between 1994 and 1997. The data
 files contain information from the Demographic File protocol. The data
 files contain basic demographic information, as well as information
relevant to race/ethnicity and family acculturation.</p></abstract>
           
 			
           <abstract><p><hi>Project on Human Development in Chicago 
 Neighborhoods</hi></p>
 <p>The city of Chicago was selected as the research site for the PHDCN
 because of its extensive racial, ethnic, and social-class diversity.
 The project collapsed 847 census tracts in the city of Chicago into
 343 neighborhood clusters (NCs) based upon seven groupings of
 racial/ethnic composition and three levels of socioeconomic status.
 The NCs were designed to be ecologically meaningful. They were
 composed of geographically contiguous census tracts and geographic
 boundaries, and knowledge of Chicago's neighborhoods were considered in
 the definition of the NCs. Each NC was comprised of approximately
 8,000 people.</p>
 <p><hi>Longitudinal Cohort Study</hi></p>
 <p>For the Longitudinal Cohort Study, a stratified probability sample
 of 80 neighborhoods was selected. The 80 NCs were sampled from the 21
 strata (seven racial/ethnic groups by three socioeconomic levels) with
 the goal of representing the 21 cells as equally as possible to
 eliminate the confounding between racial/ethnic mix and socioeconomic
 status. Once the 80 NCs were chosen, then block groups were selected
 at random within each of the sample neighborhoods. A complete listing
 of dwelling units was collected for all sampled block groups.
 Pregnant women, children, and young adults in seven age cohorts
 (birth, 3, 6, 9, 12, 15, and 18 years) were identified through
 in-person screening of approximately 40,000 dwelling units within the
 80 NCs. The screening response rate was 80 percent. Children within
 six months of the birthday that qualified them for the sample were
 selected for inclusion in the Longitudinal Cohort Study. A total of
 8,347 participants were identified through the screening. Of the
 eligible study participants, 6,228 were interviewed.</p>
 <p>For all cohorts except 0 and 18, primary caregivers as well as the
 child were interviewed. The primary caregiver was the person found to
 spend the most time taking care of the child. Separate research
 assistants administered the primary caregiver interviews and the child
 interviews. The primary method of data collection was face-to-face
 interviewing, although participants who refused to complete the
 personal interview were administered a phone interview. Interviews
 were conducted in Spanish, English, and Polish. In Wave 1 the complete
 protocol was translated into Spanish and Polish. An interpreter was
 hired for participants who spoke a language other than English,
 Spanish, or Polish. Depending on the age and wave of data collection,
 participants were paid between $5 and $20 per interview. Other
 incentives, such as free passes to museums, the aquarium, and monthly
 drawing prizes were also included.
 </p> 
 <p>Interview protocols included a wide range of questions. For
 example, some questions assessed impulse control and sensation-seeking
 traits, cognitive and language development, leisure activities,
 delinquency and substance abuse, friends' activities, and
 self-perception, attitudes, and values. Caregivers were also
 interviewed about family structure, parent characteristics,
 parent-child relationships, parent discipline styles, family mental
 health, and family history of criminal behavior and drug use.</p>
 <p><hi>Demographic File</hi></p>
 <p>
 For Cohorts 0 through 15, the primary caregiver answered
questions. For Cohort 18, the subject answered questions.</p></abstract>
           
 			
          <abstract>The data files contain demographic information
 regarding the subject's residency. The files also contain information
 concerning the primary caregiver's residency, use of language,
 education, ethnicity, religion, marital status, as well as the same
 information for the primary caregiver's partner, and the subject's
biological father and mother.</abstract>
