Dallas Fed Working Paper: How Unauthorized Immigration Moved Rents and Home Prices in 2021–2024

What the working paper is (and isn’t)

A working paper from the Federal Reserve Bank of Dallas estimates how the 2021–2024 surge in unauthorized immigration affected local labor and housing markets. It is explicitly a preliminary draft circulated for professional comment and does not necessarily reflect the views of the Federal Reserve System. [foxbusiness.com]

The key nuance is scope: the paper estimates a local demand shock. That is different from claiming it explains all (or even most) of today’s national housing unaffordability. The measured effects depend on where people settle and how constrained local supply is. [foxbusiness.com]

The core housing findings

Across metros during the boom period (March 2021 to March 2024), the authors estimate that an increase in unauthorized immigrant worker flows equal to 1% of a local area’s initial employment is associated with:

• about **+2.2%** local house prices
• about **+1.4%** local rents [dallasfed.org]

The paper also presents a contribution-style decomposition suggesting these flows could explain roughly 30% of the growth in house prices and about 20% of the growth in rents over that period for the average local market in their sample. This is a contribution over a specific window, not a claim that prices are 30% higher everywhere in level terms. [dallasfed.org]

Supply response: why prices moved

The mechanism is straightforward: when a market with limited slack absorbs a population inflow, housing costs can adjust faster than new supply. In the authors’ results, the estimated effects on permitting are small and statistically insignificant across segments, consistent with short-run supply inelasticity. [dallasfed.org]

The paper also notes possible offsets (for example, higher occupancy per unit) that could dampen rent pressure. Even so, the estimates still show a net upward effect on rents and prices in the places with larger inflows. [dallasfed.org]

How to use this in market analysis

**1) Underwrite local sensitivity, not headlines.** The practical takeaway for housing analysts is that demand shocks can translate into higher rents and prices where supply is slow to respond. The same shock can look very different in a high-building metro versus a constrained one.

**2) Pair demand signals with supply indicators.** Track vacancy, absorption, permits, and completions. If the pipeline is thin, incremental demand tends to show up in pricing sooner.

**3) Be careful with contribution math.** A statement about share of growth over March 2021 to March 2024 is not the same as a statement about the overall level of housing costs today. Keep the time window and definitions front and center. [dallasfed.org]
