At A Glance

Noteworthy Characteristics

  • Provides measured height and weight data.
  • Provides physical activity measures that distinguish activity outside of school.
  • Provides geospatial data at the zip code, census tract, and block level.
  • Three-wave longitudinal survey embedded in more than four decades of linkable data collected in the Panel Study of Income Dynamics (PSID).
  • Features a genealogical panel with links to parental and grandparental data obtained in the PSID. It also has data on substantial numbers of sibling pairs in each wave of the Child Development Supplement.

Purpose

To collect longitudinal data on food expenditures, food security, nutritional knowledge, and other content for families in the United States (U.S.) with children ages 0 to 18 years. To collect data on weight status and dietary and exercise practices for children in these families.

Target Population

U.S. children ages 0 to 18 years and their caregivers.

Conducted

Began in 1997. Conducted in three waves in 1997, 2002-2003, and 2007-2008. Most recent year conducted was 2014.

The Transition into Adulthood (TA) Study was conducted in 2005, 2007, 2009, and 2011. The TA Study will continue to gather information on these individuals through at least 2015, or when they are eligible to join the PSID sample.

CDS-2014 questionnaires were revised and updated to include content that reflects the current circumstances of children’s family, neighborhood, and school contexts. Three key changes include:
• New content on children’s access to and use of computers and other electronic devices for learning, socializing, and entertainment. This new content appears in the questionnaires administered to primary caregivers (PCGs) and children as well as in time diaries.
• Updated questions in the adolescent interview to reflect changes in patterns of substance use since 2007.
• New questionnaire content measuring children’s prosocial behavior.

Sponsor

The study is funded by the National Science Foundation; the National Institute on Aging, the Eunice Kennedy Shriver National Institute of Child Health and Human Development, and the Office of the Assistant Secretary for Planning and Evaluation (U.S. Department of Health and Human Services); the Economic Research Service (U.S. Department of Agriculture); the U.S. Department of Housing and Urban Development; the U.S. Department of Labor; and the Center on Philanthropy at the Indiana University-Purdue University.

Special Note(s)

The Child Development Supplement (CDS) is one research component of the Panel Study of Income Dynamics (PSID), which was begun in 1968. The PSID is a longitudinal study of a representative sample of U.S. individuals and their families. The PSID has collected data on family composition changes, housing and food expenditures, marriage and fertility histories, employment, income, time spent in housework, health, consumption, wealth, and more.

The CDS collected information on children (ages 0 to 12 years in 1997) whose parents participated in the PSID. This cohort of children was interviewed in 1997 (CDS-I); 2002-2003 (CDS-II) and 2007-2008 (CDS-III). When these children were younger than age 18 years, they were included in the CDS. When they were age 18 years and older, they participated in the Transition Into Adulthood Study.

Sampling

Sample Design

Panel/longitudinal survey that selected up to two children ages 0 to 12 years in Panel Study of Income Dynamics (PSID) families. Of the approximately 3,600 children in the first wave (CDS-I), approximately 76% had a sibling who also participated in the study.

Nationally representative sample of children and their primary caregivers. In the initial PSID sample, minority and low-income families were oversampled, resulting in a substantial number of Black families. Learn more about the sampling design.

Sample Size

CDS-I: Approximately 3,600 children and 2,400 families in 1997-1999.
CDS-II: Approximately 2,900 children and adolescents and 2,000 families in 2002-2003.
CDS-III: Approximately 1,500 children and adolescents and 1,600 families in 2007-2008.
CDS-2014: 4,333 children and adolescents and 2,517 caregivers

Special Note(s)

CDS-I children also were part of the PSID sample at time of PSID 1997 interview; CDS-II children also were part of the PSID sample at the time of the 2001 interview; CDS-III children also were part of the PSID sample at the time of the 2007 interview.

Cognitive assessments were obtained using the Woodcock Johnson Tests of Achievement and WISC Digit Span Test for Short Term Memory.

In addition to the survey measures, time diary information was collected on a random weekday and a random weekend day from approximately 2,900 children in CDS-I, 2,600 children in CDS-II, and 1,400 children in CDS-III.

Self-reported information was collected from children ages 10 years and older at the time of the interview.

The sample includes approximately equal in the number of boys and girls. The CDS includes approximately 1,100 White families; 1,000 Black families; 200 non-White, non-Black Hispanic families; and 46 Asian families; 12 Native American families; and 29 families of other nationalities.

Data Access and Cost

Data Availability

Obtain data by going to the Panel Study of Income Dynamics (PSID)-CDS Data Center website. Follow the instructions for requesting customized data files and documentation.

Cost

All public data are free of charge.

Special Note(s)

Restricted data (geocodes and school administrative data) are provided only to individuals who meet requirements and enter into a contract with the University of Michigan. Contracts must be renewed every 180 days for a total contractual period of 3 years. To initiate the contract process, the following materials must be submitted for review: a research statement; a data protection plan; Institutional Review Board approval from one’s home institution; and an administrative processing fee of $750. Upon approval of these materials, a contract will be sent to the requestor’s institution. Contact psidhelp@umich.edu for more information.

The most recent year for which data are available is not necessarily the most recent year this survey was conducted.

Geocode/Linkage

Geocode Variable(s)

Geocode variables available by special agreement (see Special Notes under Data Access and Cost): zip code, census tract, census block, county, and state; National Center for Education Statistics school identifier and school district identifier.

Existing Linkages

Using school identifiers, Child Development Supplement (CDS) data on children and adolescents have been linked to National Center for Educational Statistics Common Core of Data (NCES/CCD) information on public school characteristics and Private School Universe Survey/Private School Survey Series (PSS) information on private school characteristics.

CDS data can be linked to the Panel Study of Income Dynamics survey. Parent, grandparent, and sibling data can be examined.

Special Note(s)

School identifiers needed to link to CCD and PSS data are considered restricted and are available only by special agreement (see Special Notes under Data Access and Cost).
