What this research studies

This project uses long-running U.S. and Danish surveys and population records to map when grandparents, parents, and children lived at the same time. It compares people born in different decades and different education or income groups to see how generational overlap has changed. The researchers link those overlap patterns to measures of family support, childcare, and child wellbeing. The work combines harmonized data from sources like the PSID, Add Health, Danish population registers, and SHARE to make cross-country and historical comparisons.

Who could benefit from this research

Good fit: This work is most relevant to parents, grandparents, and children interested in how family timing and longevity affect caregiving and resources across generations.

Not a fit: People whose concerns are unrelated to family structure or intergenerational support may see little direct benefit from these findings.

Why it matters

Potential benefit: If successful, the findings could help policymakers and families identify which children are likely to have multigenerational support and guide programs that strengthen family resources and child wellbeing.

How similar studies have performed: Past demographic and family-structure studies have linked family composition to child outcomes, but a harmonized cross-national analysis focused specifically on generational overlap is relatively novel.
