Harvard's Joint Center for Housing Studies estimates immigration policy will reduce household formation by 500,000 per year from 2024 to 2027. The national rental vacancy rate rose from 7.1% in the third quarter of 2025 to 7.6% in the same period this year.
Why it matters
The projected loss of about 2 million households, mainly renters, reflects how changes in immigrant entry affect housing demand across the country. Builder sentiment has also worsened amid immigration crackdowns, adding uncertainty to the rental and homebuying markets.
The estimate covers 2024 to 2027 and is attributed to immigration policy curbing entry on work and student visas. Census Bureau vacancy survey data was used to measure the slowdown, but the long-term trajectory remains unclear.
The players
Harvard's Joint Center for Housing Studies
A Harvard University research center that analyzes U.S. housing markets, demand and household trends.
The details
Immigration policy reduces household formation by curbing immigrant entry on work and student visas. Immigrants who entered from 2022 to 2024 formed 571,000 net new renter households, and at least one Fed study indicated illegal immigration may have driven up housing costs during the Biden administration.
Timeline
2022 to 2024: Immigrants form 571,000 net new renter households.
Third quarter of 2025: Rental vacancy rate is 7.1%.
2024 to 2027: Immigration policy reduces annual household formation by 500,000.
Third quarter of 2026: Rental vacancy rate reaches 7.6%.
2027: Immigrants are projected to form 132,000 new households.
Roadmap
The Joint Center's household formation analysis is now being applied to immigration policy, which it links to a slowdown in new renter households. This places the rental slowdown within a broader debate over how immigrant entry shapes housing demand.
Renters may find more available units as vacancy rises, but the slowdown in household formation could shift rent levels and lease terms over time. Prospective renters and buyers should watch vacancy and rent data closely as immigration policy changes.
The takeaway
Immigration policy is now a measurable factor in the rental market, and renters and housing watchers should track vacancy rates and household growth closely as the policy takes effect.
