Federal Reserve paper links Biden-era illegal immigration surge to sharp increases in home prices and rents

A Federal Reserve Bank of Dallas working paper has put hard numbers on what millions of American renters and homebuyers already suspected: the record wave of illegal immigration between 2021 and 2024 drove housing costs significantly higher in metropolitan areas across the country. The paper found that unauthorized immigrant worker flows accounted for roughly 30% of home-price growth and about 20% of rent growth in the average metro area during that three-year stretch, the New York Post reported.

The finding lands at a moment when housing affordability remains one of the top economic anxieties for working families. And it traces a direct line from the Biden administration's border policies to the kitchen-table costs that squeezed household budgets from coast to coast.

The Dallas Fed researchers combined immigration court records with government administrative data to measure how surges in unauthorized workers rippled through local labor and housing markets. Their core metric: for every 1% increase in unauthorized workers relative to a local labor force, home prices rose approximately 2.2% and rents climbed roughly 1.4%. Employment grew by about 1%, but average wages showed no measurable decline.

The numbers behind the housing squeeze

The study period ran from March 2021 through March 2024, essentially the first three years of the Biden presidency. The paper described the illegal immigration wave during that window as an "unprecedented boom."

Congressional Budget Office estimates cited by the researchers put the scale of the surge at roughly 7 million people added to the U.S. population through net unauthorized immigration before flows slowed sharply around mid-2024. That population shock translated directly into housing demand in metro areas where supply was already tight.

The paper found little evidence that homebuilding expanded enough to absorb the added demand. In other words, the influx operated as a demand shock slamming into a market with no room to give. Prices rose. Rents rose. And the people already competing for scarce housing, legal residents, young families, lower-income workers, paid the price.

Unauthorized immigrant worker flows accounted for about 30% of employment growth in the average metro area over the study period. That same 30% figure applied to home-price growth. Rent growth attributable to the surge came in at roughly 20%.

What the paper does, and does not, claim

The Dallas Fed authors were careful to note that their estimates apply to the average metropolitan area studied and do not suggest immigration was the sole driver of rising housing costs nationwide. The remaining 70% of home-price growth and 80% of rent growth came from other factors the paper does not detail in the portions reported.

The working paper also carries a standard disclaimer: it is a preliminary draft circulated for professional comment and does not necessarily reflect the views of the Federal Reserve Bank of Dallas or the Federal Reserve System. The specific authors were not named in available reporting.

None of that softens the central finding. Even if illegal immigration explains "only" 30% of home-price increases, that is an enormous share of cost growth driven by a policy failure the federal government chose not to address for years. The Biden administration's approach to the southern border, marked by a pattern of enforcement decisions that critics say repeatedly prioritized leniency over public safety, now has a Fed-backed price tag attached to it.

Demand shock in a supply-starved market

The mechanism the paper describes is straightforward economics. Add 7 million people to the population. Concentrate that growth in metro areas where jobs exist. Watch those new arrivals compete for the same rental units and starter homes that legal residents need. When builders can't keep up, and the paper says they didn't, prices go up.

The study found no evidence that the immigration surge reduced average wages, which undercuts one common progressive talking point: that illegal immigrants take jobs and suppress pay. But it also undercuts the other progressive talking point, that mass immigration carries no meaningful economic cost for existing residents. The cost showed up not in paychecks but in housing bills.

For a young couple trying to buy a first home, or a single mother watching her rent climb year after year, the distinction between a wage cut and a rent hike is academic. The money leaves the household either way.

The consequences of the Biden-era border posture extended well beyond housing costs. Across the country, communities dealt with the downstream effects of an immigration system operating without meaningful enforcement. In one case, a Haitian immigrant was charged in the fatal hammer attack on a Florida mother, an incident that drew sharp criticism of the administration's enforcement record. The housing data from the Dallas Fed adds a quieter but broader dimension to that same failure, one measured in dollars rather than headlines.

A political legacy written in rent checks

The Biden administration spent much of its tenure arguing that immigration was an economic positive and that enforcement-first approaches were both cruel and unnecessary. Allies in Congress and the media echoed that framing. The Dallas Fed paper does not engage in political argument, but its data tells a story the administration never wanted told: that the border surge it presided over made housing more expensive for the very working-class Americans Democrats claim to champion.

Biden himself has largely receded from public political life since leaving office. As Obama continues headlining Democratic campaigns, Biden has quietly faded from the stage, but the policy consequences of his tenure have not faded with him.

The working paper's methodology, matching immigration court records to administrative data at the metro-area level, gives the findings a granularity that broad national averages often lack. It allows the researchers to isolate the local labor-market and housing-market effects of unauthorized worker inflows, rather than relying on aggregate trends that blend legal and illegal immigration together.

Several open questions remain. The paper does not specify which metro areas were included in the dataset, nor does available reporting identify the exact government administrative data sources the researchers used. Whether the paper distinguishes among asylum seekers, parolees, and other categories of unauthorized entrants, or treats them as a single group, is also unclear. And the study has not undergone formal peer review; it remains a preliminary draft.

Those caveats matter. But they do not erase the core finding, which aligns with what housing economists and local officials in high-immigration metros have been saying for years: rapid population growth in supply-constrained markets pushes costs up. The Dallas Fed simply quantified the share of that growth attributable to illegal immigration, and the number is large.

Who bears the cost

The people most harmed by a 30% contribution to home-price growth and a 20% contribution to rent increases are not hedge-fund managers or tech executives. They are hourly workers, young families, retirees on fixed incomes, and legal immigrants who followed the rules and now compete for housing against a population that arrived outside the law.

Meanwhile, the Biden family's public profile has taken its own peculiar turns. Hunter Biden recently returned to social media with provocative posts, a reminder that the family name remains in the public eye even as the policy record it left behind continues to generate consequences for ordinary Americans.

The Dallas Fed paper does not prescribe policy solutions. It measures effects. But the effects it measures point in one direction: when a government allows millions of unauthorized entrants into the country without expanding housing supply or enforcing immigration law, existing residents pay more to keep a roof over their heads.

That isn't a theory. It's a Fed working paper with data behind it. And it confirms what taxpayers and renters already knew, that someone eventually picks up the tab for open borders, and it isn't the people who opened them.
