This episode from the American Real Estate and Urban Economics Association (AREUEA) explores why some young adults live with their parents and how parental resources shape that decision. The study Coresidence: How parental characteristics matter, authored by Penn IUR Co-Director Susan Wachter along with Penn IUR affiliates Arthur Acolin and Desen Lin, finds that larger, owner-occupied parental homes make co-residence more likely, while greater parental wealth can help young adults live independently. These parental factors matter even more in less affordable housing markets and have become increasingly important over time.
