Short answer. By age 30, baby boomers had a homeownership rate of approximately 50%; millennials at age 30 reached approximately 42% — an 8-percentage-point gap.
The Federal Reserve's Survey of Consumer Finances and the Census Bureau's Housing Vacancy Survey both track generational homeownership. The gap between millennials and boomers at the same life stage is significant but smaller than commonly portrayed.
Homeownership rate by age 30
- Boomers (born 1946-1964, reached age 30 between 1976-1994): ~50%
- Gen X (born 1965-1980, reached age 30 between 1995-2010): ~46%
- Millennials (born 1981-1996, reached age 30 between 2011-2026): ~42%
Why the gap exists
Three primary factors. First, affordability — the price-to-income ratio rose from 2.4× (1985, when older boomers were buying) to 5.4× (2024, when older millennials are buying). Second, student-loan debt — average outstanding student debt for households under 35 reached $33,500 by 2024, vs. essentially $0 for boomers at the same age. Third, delayed household formation — millennials marry and have children later than prior generations, delaying the trigger event for home purchase.
The catch-up dynamic
Millennial homeownership is rising sharply: by age 40, millennials approached 60% homeownership — only modestly behind boomers' 64% at the same age. The gap narrows over time, suggesting much of it is a delay effect rather than a permanent generational divergence.
Wealth implications
The 5-10-year delay in millennial home purchase has meaningful wealth implications: a household that buys at age 35 vs. 25 misses 10 years of equity buildup, which compounds over a 30-year mortgage to roughly $200K-$300K in lost net-worth accumulation.
