The PSID is the world's longest-running nationally representative household panel survey. With over 50 years of data on the same families and their descendants, the PSID is a cornerstone of the data infrastructure for empirically based social science research in the U.S. PSID gathers data on the family as a whole and on individuals residing within the family, emphasizing the dynamic and interactive aspects of family economics, demography, and health. PSID data were collected annually from 1968-1997 and biennially after 1997. In the Main Interview, one person per family is interviewed on a regular basis. Information about each family member is collected, but much greater detail is obtained about the reference person and, if married/cohabitating, the spouse or long-term cohabitor. Survey content changes to reflect evolving scientific and policy priorities, although many content areas have been consistently measured since 1968. Information includes employment, income, wealth, expenditures, health, education, marriage, childbearing, philanthropy, and numerous other topics. With low attrition and high success in following young adults as they form their own families, the sample size has grown from roughly 5,000 families in 1968 to more than 10,000 families and 24,000 individuals by 2017. Over the course of the study, the PSID has distributed data on more than 80,000 individuals. The long panel, genealogical design, and broad content of the data offer unique opportunities to conduct generational and life-course research. The PSID now contains thousands of inter- and intragenerational relationships over 50 years of data, including:
- "Paired" generational relationships, with each family in the pair providing independent interviews (as of the 2017 wave)
- Parent-Adult Child pairs: ~5,500
- Sibling pairs: ~3,600
- Cousin pairs: ~4,500
- "Tripled" generational relationships, with all three generations providing independent interviews (as of the 2017 wave)
- Grandparent-Parent-Adult Child triplets: ~1,400
