A new working paper from the Federal Reserve Bank of Dallas suggests that a substantial increase in immigration has been a contributing factor to the rise in U.S. housing costs. The paper estimates that approximately 7 million unauthorized immigrants entered the country between 2021 and 2024, creating a demand shock in local housing markets.

According to the research, this surge in demand, in a market with limited housing supply in the short term, is associated with 30% of home price growth and 20% of rent increases. While the authors emphasize that the paper is a preliminary draft and does not represent the views of the Federal Reserve System, its findings highlight the economic principle that increased demand, with constant supply, leads to higher costs.

This perspective challenges earlier assertions from some political figures who faced criticism for attributing rising housing costs to immigration. For instance, in 2024, Donald Trump and J.D. Vance made statements linking immigration to housing affordability issues, which were met with widespread fact-checking and accusations of scapegoating. Media outlets, including The Washington Post and The New York Times, reported that economists largely disagreed with these claims at the time.

The paper's findings suggest that Democratic policies, which have promoted increased immigration while simultaneously implementing regulations that limit housing supply, may have exacerbated the affordability crisis. In New York City, Mayor Zohran Mamdani, who campaigned on affordability, has supported sanctuary city policies and increased funding for immigrant legal defense, which critics argue could further strain housing resources.

Beyond policy, the Federal Housing Finance Agency under the Biden administration expanded eligibility for mortgages to non-permanent residents, including those with DACA, H-1B visas, and green cards. These programs allowed buyers with lower credit scores and smaller down payments access to homeownership at a time when many Americans are struggling with housing expenses.

The impact of rising housing costs is particularly significant for younger generations. A report indicates that 67% of Gen Z individuals are experiencing difficulties with housing expenses, leading 84% to postpone major life milestones such as marriage and having children. The article suggests a correlation between these economic pressures and a growing favorable view of socialism among this demographic.
