The claim that Former President Biden’s illegal immigration surge directly caused a 30% rise in home prices and a 20% rise in rents is false because while some Federal Reserve working papers estimate unauthorized immigration contributed to portions of housing cost increases, the timing, scale, and causality are disputed and not conclusively established as the primary driver of such large price hikes.

Key Evidence
Federal Reserve working papers estimate unauthorized immigration contributed to portions of housing cost increases but do not claim full causality for total rises.
The Joint Center for Housing Studies finds timing mismatches between immigration surges and housing price spikes.
FactCheck.org warns against exaggerated claims linking illegal immigration directly to housing unaffordability without considering other factors.

The Joint Center for Housing Studiesjchs.harvard.edujchs.harvard.eduThe Role of the Recent Immigrant Surge in Housing Costs points out that the timing of immigration surges does not align well with the initial rapid growth in housing costs at the start of the COVID-19 pandemic, suggesting other factors played major roles. Additionally, FactCheck. Org
factcheck.orgfactcheck.orgVance's Misleading Claims on Housing Prices and Illegal Immigration highlights that claims linking illegal immigration to housing unaffordability often exaggerate figures or omit broader market dynamics.
The Federal Reserve study itself notes varying effects across regions and does not attribute all housing cost increases to immigration alone. Other economic factors such as supply constraints, demand shifts, pandemic-related disruptions, and monetary policy also significantly influenced housing prices and rents during this period.
Therefore, attributing a direct causal surge in home prices and rents solely to Biden-era illegal immigration inflows oversimplifies a complex issue and misrepresents the evidence.
