Rising Housing Costs Keep One-Third of Young Adults at Home

Approximately 32% of U.S. adults under the age of 35 are currently living with their parents or other family members, according to data from the U.S. Census Bureau. This living arrangement, often termed “doubling up,” is driven primarily by record-high home prices and elevated mortgage interest rates that have pushed the dream of homeownership out of reach for many in the millennial and Gen Z cohorts.

Why are more young adults living with parents?

The primary driver for this trend is the significant decline in housing affordability. According to the National Association of Realtors (NAR), the share of first-time homebuyers has fallen to historic lows, hovering near 26% of all home sales. High interest rates, which have remained well above the lows seen during the pandemic, have increased monthly mortgage payments, making it difficult for younger workers to qualify for loans or save for a down payment.

Data from the Bureau of Labor Statistics indicates that while wage growth has occurred, it has failed to keep pace with the cumulative rise in median home prices over the last four years. Consequently, living at home has transitioned from a temporary financial bridge to a long-term necessity for many, as rent prices in major metropolitan areas also remain near record highs.

How do current figures compare to historical trends?

The current percentage of young adults living at home marks a departure from the mid-20th-century standard, though it mirrors patterns seen during the Great Depression. According to analysis from the Pew Research Center, the share of young adults living in multi-generational households began a steady climb following the 2008 financial crisis and accelerated sharply during the 2020 COVID-19 pandemic.

While some analysts suggest this is a “new normal,” others point to the divergence between historical norms and current economic reality:

• 1980s–2000s: The share of young adults living with parents remained relatively stable, typically between 20% and 25%.
• 2020–2024: The share consistently exceeds 30%, sustained by a combination of high inflation and limited entry-level housing inventory.

What are the consequences for the housing market?

The trend of young adults remaining in their family homes creates a feedback loop in the real estate market. Because this demographic represents the primary engine for first-time home purchases, their absence from the buying pool reduces the velocity of market turnover.

According to the Harvard Joint Center for Housing Studies, the lack of “starter homes”—smaller, more affordable properties—has prevented many young adults from transitioning out of their parents’ homes. Developers have largely focused on building larger, higher-margin properties, further restricting the supply for those entering the market for the first time.

Frequently Asked Questions

Is this trend limited to specific regions?
No, the trend is national, though it is most pronounced in high-cost-of-living urban centers such as Los Angeles, New York, and San Francisco, where the rent-to-income ratio is significantly higher than the national average, according to the Department of Housing and Urban Development (HUD).

Are there social benefits to this trend?
Some economists note that multi-generational living can improve household financial stability by pooling resources, allowing families to pay down debt or save for future investments more effectively than they could in separate households.

When is this trend expected to shift?
Market analysts generally agree that a sustained decline in mortgage interest rates or a significant increase in the construction of entry-level housing units would be required to shift the current trajectory. As of early 2024, the Federal Reserve maintains a cautious stance on interest rate adjustments, suggesting that housing affordability challenges may persist in the near term.
