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. For primary caregivers included in Wave 3 but not in Wave 2, an addendum interview was administered consisting of measures or portions of measures from the Wave 2 interview. This included questions from PROJECT ON HUMAN DEVELOPMENT IN CHICAGO NEIGHBORHOODS (PHDCN): DEMOGRAPHIC FILE, WAVE 2, 1997-2000 (ICPSR 13609), PROJECT ON HUMAN DEVELOPMENT IN CHICAGO NEIGHBORHOODS (PHDCN): MY CHILD'S EXPOSURE TO VIOLENCE, WAVE 2, 1997-2000 (ICPSR 13619), PROJECT ON HUMAN DEVELOPMENT IN CHICAGO NEIGHBORHOODS (PHDCN): FAMILY SUICIDE INTERVIEW, WAVE 2, 1997-2000 (ICPSR 13623), PROJECT ON HUMAN DEVELOPMENT IN CHICAGO NEIGHBORHOODS (PHDCN): HOUSEHOLD COMPOSITION, WAVE 2, 1997-2000 (ICPSR 13628), PROJECT ON HUMAN DEVELOPMENT IN CHICAGO NEIGHBORHOODS (PHDCN): HEALTH SCREEN, WAVE 2, 1997-2000 (ICPSR 13629), and PROJECT ON HUMAN DEVELOPMENT IN CHICAGO NEIGHBORHOODS (PHDCN): PRENATAL AND EARLY HEALTH, WAVE 2, 1997-2000 (ICPSR 13644). It was administered to primary caregivers in Cohorts 0, 3, 6, 9, and 12.

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 Caregiver-Subject Conflict Scale (CSC). The CSC was administered to the primary caregiver (PC) of subjects belonging to Cohorts 0-15. This Wave 2 study was modified from the Wave 1 parent-child version of the Conflict Tactics Scale (PROJECT ON HUMAN DEVELOPMENT IN CHICAGO NEIGHBORHOODS (PHDCN): CONFLICT TACTICS SCALE FOR PARENT AND CHILD, WAVE 1, 1994-1997 [ICPSR 13584]) by adding items related to more positive forms of disciplinary tactics, modifying the response scale, and inquiring about tactics used not only by the PC, but by any adult household member. The CSC asked if any of several different ways of settling problems with the subject were used by any adult household member in the past year.

One such measure was the Interviewer Impressions (Primary Caregiver). This set of questions was completed by the interviewer at the end of each interview with a primary caregiver(PC). Basic demographic information was collected. Also, the interviewer was asked to rate the behavior of the PC toward the interviewer and the PC's behavior and attitude toward the subject and other household members. It was completed for Cohorts 0, 3, 6, 9, 12, and 15.

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 Household Composition listing, administered to either the primary caregivers of subjects belonging to Cohorts 0 to 15, or to the subjects belonging to Cohort 18. It obtained basic information on the composition of the subject's household and included each household member's age, gender, and relationship to the subject. In Wave 1, this information was incorporated into the Family Structure and Health History (PROJECT ON HUMAN DEVELOPMENT IN CHICAGO NEIGHBORHOODS (PHDCN): FAMILY STRUCTURE AND HEALTH HISTORY, WAVE 1, 1994-1997 [ICPSR 13592]).

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 was the Conflict Tactics Scale for Parent and Child (CTSS). The CTSS, administered to the primary caregiver (PC) of subjects belonging to Cohorts 0, 3, 6, and 9, measured psychological and physical maltreatment and neglect of children by their PC or any other adult family or household member, as well as nonviolent modes of discipline. The CTSS also measured the extent to which an adult carried out specific acts of physical and psychological aggression, regardless of whether the child was injured. This Wave 3 study was modified from the Wave 1 parent-child version of the Conflict Tactics Scale used in PROJECT ON HUMAN DEVELOPMENT IN CHICAGO NEIGHBORHOODS (PHDCN): CONFLICT TACTICS SCALE FOR PARENT AND CHILD, WAVE 1, 1994-1997 (ICPSR 13584). It is also related to PROJECT ON HUMAN DEVELOPMENT IN CHICAGO NEIGHBORHOODS (PHDCN): CAREGIVER-SUBJECT CONFLICT SCALE, WAVE 2, 1997-2000 (ICPSR 13612).

It collected information relating to participation in community groups, as well as information about the neighborhood. Some of the questions used were drawn from PROJECT ON HUMAN DEVELOPMENT IN CHICAGO NEIGHBORHOODS: COMMUNITY SURVEY, 1994-1995 (ICPSR 2766). The same set of questions was administered to subjects in Cohorts 15 and 18 in PROJECT ON HUMAN DEVELOPMENT IN CHICAGO NEIGHBORHOODS (PHDCN): COMMUNITY INVOLVEMENT AND COLLECTIVE EFFICACY (YOUNG ADULT), WAVE 3, 2000-2002 (ICPSR 13686).

The Census 2000: Special Tabulation on Aging provides information for each of the 50 states along with the District of Columbia and Puerto Rico with a special focus on persons age 60 and older. Population topics (Tables P001 through P116 for each state and state equivalent file) include basic population totals, age, sex, race, Hispanic or Latino origin, households and families, group quarters, marital status, grandparents as caregivers, ability to speak English, place of birth, citizenship status, migration, educational attainment, veteran status, disability, employment status, income, and poverty status. Household topics (tables H01 through H69) include tenure (owner occupied or renter occupied), household size, units in structure, year structure was built, availability of plumbing and kitchen facilities, and whether meals are included in the rent and value of home. Both the population and housing subjects may be cross tabulated. Files are organized according to the ten regions as defined by the Administration on Aging. Each table provides information at a number of geographical levels: United States (50 states + DC), state, Planning and Service Area (PSA -- the geographic area served by a single area agency on aging), county, county subdivision in 12 states with a population of 2,500 or more, places with a population of 2,500 or more, and census tract, as well as American Indian and Alaska Native areas. Also, the urban and rural components of states and PSAs are shown. The data are in the form of Excel tables. The technical documentation provides extensive details about such topics as the tabulation specifications, the geographical levels shown, how to use the statistical tables, and the measures used to protect confidentiality.
