What this research studies

If you are a parent, grandparent, or have children, this research examines how long different generations live at the same time and how that affects family help and resources. The team combines long-running U.S. surveys and Danish population registers to measure how common multi-generation overlaps are and how they changed over the 20th century. They compare patterns across socioeconomic groups and between the two countries to see how policy and history shape family connections. Results come from harmonized data analysis rather than new clinical visits or interventions.

Who could benefit from this research

Good fit: Ideal candidates are families that span three generations—grandparents, parents, and children—especially those who can share survey or registry information about family structure and timing of births and deaths.

Not a fit: People without multigenerational family connections (no living parents, grandparents, or children) are less likely to be directly affected by the study's findings.

Why it matters

Potential benefit: Findings could inform policies and programs that strengthen family support networks and improve child and family wellbeing over the life course.

How similar studies have performed: Large population surveys and register-based studies have successfully linked family structure to child and adult outcomes, but the cross-country, historical comparison of generational overlap in this project is relatively novel.
