Study History

The PSID was originally created to study the dynamics of income and poverty. Over the past five decades, the study has been expanded to collect information on health, wealth, expenditures, philanthropy, child development, the transition to adulthood, and much more.

A detailed history of the study and sample can be found in Chapters 1 and 2 of the current User Guide


A Study of Families – A Family of Studies

The PSID has now collected data for 50 years from more than 77,000 individuals. As of 2017, more than 11,000 families are followed, and there are as many as six generations represented within sample families.

Several supplemental studies have been undertaken as well. Two ongoing supplements focus on child development and the transition into adulthood. Additional supplements on aging, disability, intergenerational transfers, and well-being have also been collected. Please see below for more details.

Ongoing Supplements


Child Development Supplement (CDS)

The CDS provides researchers with extensive data on children and their families to study the dynamic process of early human and social capital formation. The study collects data on children’s health, development, and well-being within the context of the family, school, and neighborhood.

The Original CDS was started in 1997, following a cohort of children 0 to 12 years of age across three waves of data collection over the course of a decade. In 2014, the CDS was relaunched as an ongoing longitudinal study that collects data on all children in PSID families 0 to 17 years of age.
 


Transition into Adulthood Supplement (TAS)

The Transition into Adulthood Supplement (TAS) began in 2005 to follow children from the original CDS cohort into young adulthood, collecting six waves of data through 2015. The study was relaunched in 2017 to follow all PSID sample children who are entering early adulthood, and who comprise the future focal sample members of Core PSID.

Information is collected on many domains including psychological functioning, family formation, fertility-related behavior, cohabitation, childhood adversity, computer skills, responsibilities, employment and income, education and career goals, and health.


One-Time Supplements


Disability and Use of Time Supplement (DUST)

DUST collected information in 2009 and 2013 to investigate the connections between disability, time use, and well-being for older adults.

Information was obtained using time diaries about what respondents did, where they were, who did the activities with them, who else was there, how they felt, and for household and care-related activities, for whom the activity was carried out. Information was also collected about the respondent’s health, functioning, well-being, and stylized time use and participation measures.
 


Childhood Retrospective Circumstances Study (CRCS)

The CRCS collected data in 2014 from household heads and, if married/cohabitating, spouses/partners on childhood experiences, including health, socioeconomic status, neighborhood quality, relationships, school experiences, and exposure to the criminal justice system.


Wellbeing and Daily Life Supplement (WB)

The Wellbeing and Daily Life Supplement collected data in 2016 from household heads and spouses/partners ages 30 and above on well-being, personality traits, and every day skills.


Family Roster and Transfers Module (R&T)

The R&T Module was collected from household heads and spouses/partners during the 2013 wave of Core PSID.

The module includes summary information on family structure and whether there were any short-term transfers to and from parent units and children in the last year as well as long-term transfers from parents and to children.
