Nearly Half of US Adults Under 30 Live With Parents, Fed Survey Finds

Nearly half of American adults under 30 lived with a parent in 2025, up 12 percentage points from 2019, according to the Federal Reserve's Economic Well-Being of U.S. Households survey. The shift carries long-term consequences for wealth accumulation, marriage and fertility rates. The increase stems from high student debt, a weak entry-level job market and elevated housing costs. A Center for Retirement Research brief found that states with higher real rents and lower vacancy rates showed significantly higher rates of parental coresidence. Had 2007 rental conditions prevailed, parental living would be 1.5% lower for women and 2.1% lower for men. Rents have outpaced inflation since 2007 while the rental vacancy rate has fallen 30%. Young adults living with parents accumulate less wealth and are less likely to marry or have children, potentially straining programs like Social Security.
