Harvard's Joint Center for Housing Studies estimates that immigration policy will reduce U.S. household formation by 500,000 per year from 2024 to 2027, about 2 million households in total, mostly renters. The national rental vacancy rate rose from 7.1% in the third quarter of 2025 to 7.6% in the same period of 2026.
Why it matters
Fewer new households means fewer people competing for apartments, which helps explain the rising vacancy rate and may keep rent growth in check for renters. Builders have also grown more cautious as immigration crackdowns continue, so the rental supply picture could shift in ways households will feel over the next few years.
The national rental vacancy rate climbed from 7.1% to 7.6% between the third quarters of 2025 and 2026, using Census Bureau housing vacancy survey figures. Harvard's Joint Center for Housing Studies puts the cumulative loss at roughly 2 million households from 2024 through 2027.
The players
Harvard's Joint Center for Housing Studies
A Harvard University research center that publishes widely cited analyses of U.S. housing demand, household growth, and affordability.
U.S. Census Bureau
The federal agency whose housing vacancy survey supplies the national data used to track rental vacancy rates and household trends.
The details
Immigration policy reduces household formation by curbing immigrant entry on work and student visas, and fewer arriving immigrants means fewer new households forming, particularly renter households. Immigrants who entered from 2022 to 2024 formed 571,000 net new renter households, so the slowdown removes a source of apartment demand that had been supporting the market. Census Bureau housing vacancy survey data shows the effect in the rising vacancy rate, while at least one Fed study has suggested illegal immigration drove housing costs up during the Biden administration.
Timeline
2022 to 2024: immigrants formed 571,000 net new renter households.
Third quarter of 2025: national rental vacancy rate was 7.1%.
2024 to 2027: immigration policy reduces annual household formation by 500,000.
Third quarter of 2026: national rental vacancy rate reached 7.6%.
2027: immigrants projected to form 132,000 new households.
The Home Front
Harvard's Joint Center for Housing Studies is the source of the 500,000-per-year household formation estimate, which places this slowdown in the national debate over housing supply and demand. Rising rental vacancy shows up in the same Census Bureau survey data that housing analysts use to track the market.
If you rent, a higher national vacancy rate may give you more room to negotiate on price or terms when your lease is up, though local conditions vary. If you are thinking about buying, track how household growth and rental demand shift in your area before committing to a long-term budget.
The takeaway
Fewer new renter households is a real force in the rental market, and it is one reason vacancy is rising. Keep an eye on local vacancy figures when you plan your next lease or budget for housing costs.
