Explosive Fed Data: Unauthorized Immigration Accounted for 30% of Home Price Inflation

A new working paper from Federal Reserve economists confirms with hard data what millions of hardworking Americans already know from their checkbooks: the housing affordability crisis is being heavily driven by the border crisis.

For years, mainstream media blamed skyrocketing home prices and ungodly high rents almost entirely on low interest rates, pandemic-era migration, institutional buyers, and local zoning boards. Conveniently ignored was the massive elephant in the room: open-border policies that facilitated an unprecedented influx of millions of unauthorized arrivals.

Now, credentialed data has finally caught up to reality.

The Fed Data Breakdown

The paper, co-authored by economists at the Federal Reserve Banks of Dallas and San Francisco, uses newly available government administrative microdata and immigration court records to track the exact local economic impacts of the historic immigration wave between early 2021 and early 2024.

The findings are stark. While the massive influx acted as a positive supply shock for businesses—raising local employment roughly one-for-one—it dealt a devastating blow to the housing market.

Because housing construction completely failed to expand and absorb this sudden population surge, the influx acted as an artificial "housing demand shock." The researchers concluded that in the average metropolitan area studied, unauthorized immigration accounted for roughly 30% of total home price growth and 20% of rent inflation during this three-year window.

Shedding Harsh Light on Connecticut Policies

This federal data shines a harsh light on local housing debates right here in Connecticut. For years, state leaders have tried to solve the affordability crisis by forcing heavy-handed, high-density affordable housing mandates onto local communities, overriding municipal control and stripping towns of their zoning rights.

But the Dallas Fed paper proves they are aggressively treating the symptoms while actively worsening the cause.

Connecticut’s strict sanctuary policies have welcomed massive population inflows into a state that already suffers from a chronically restricted, fixed housing supply. This created a textbook crisis of oversupply in human capital and zero supply in physical shelter.

Between the Lines: Instead of stripping local towns of their zoning rights by forcing them to build high density affordable housing, Connecticut must address the root of the problem and reverse its sanctuary policies. Doing so would immediately ease the artificial demand shock and go a long way toward making housing affordable again for the hardworking citizens who live here. Is anyone listening in Hartford?
