Census Bureau Reports 47 Percent of US Adults Under 30 Reside with Parents in 2023

The Current Population Survey shows the share of young adults in parental homes climbed from 42 percent in 2019 to 47 percent in 2023, with the largest increases among those aged 25-29. High rents, mortgage rates above 6 percent, and student debt balances averaging $37,000 per borrower are the measurable drivers cited in the underlying microdata.

This pattern alters capital formation. Delayed household formation reduces demand for durable goods and mortgage originations, while extending the period of zero or negative net wealth accumulation for the cohort. Labor mobility data from the same survey indicate lower interstate migration rates among this group compared with prior decades.

State-level housing supply restrictions and federal student-loan policies remain the primary structural constraints. Without changes to permitting or repayment terms, the Census projection series implies multigenerational households will stay above 20 percent of total households through 2035.

Demographic knock-on effects include lower fertility rates and smaller future labor-force cohorts, which fiscal models already incorporate as reduced payroll-tax receipts after 2040.
