New Nationwide Study Finds No Crime Increase Linked to Undocumented Immigration
8/13/2026, 4:34:47 AM
Core Findings of the Neighborhood-Level Study
Researchers analyzed crime trends in 11,500 U.S. neighborhoods—representing roughly 46 million residents—between 2010 and 2018. The study, published in the *Journal of Urban Affairs*, found that neighborhoods where the share of undocumented residents grew experienced greater declines in property crime and no statistically significant change in overall violent crime. The sole exception was an increase in robberies, which the authors suggest may reflect undocumented residents being more likely victims because of higher cash usage, rather than perpetrators.
Context: Political Claims About Immigration and Crime
President Donald Trump has repeatedly asserted that undocumented immigrants are responsible for a surge in crime, labeling such incidents “Biden migrant crime” and using the claim to justify stricter border enforcement. The administration has continued to frame immigration policy as a public-safety issue, with the White House stating that its enforcement actions are “protecting our communities” and highlighting deportations of individuals charged with or convicted of crimes.
Data and Methodology
The research team estimated undocumented populations using restricted individual-level Census data accessed through a federal Research Data Center, applying an imputation method similar to that employed by the Department of Homeland Security. Co-authors include Charis Kubrin (University of California, Irvine), Derek Christopher (Stanford University), Cheyenne Hodgen (UC Irvine), Xiaoshuang Iris Luo (University of Akron), and John Hipp (UC Irvine). This approach allowed the first neighborhood-scale examination of the immigration-crime relationship, expanding beyond prior state- and metropolitan-level analyses.
Official Responses from Researchers and Government
- John Hipp explained the robbery increase as likely reflecting a “Walking ATM” phenomenon, where cash-dependent individuals become attractive targets.
- White House: In February, the administration claimed its immigration policies were “protecting our communities,” emphasizing deportations of criminal-charged immigrants as evidence of public-safety benefits.
Criticism & Opposition
President Donald Trump has used the alleged link between undocumented immigration and crime as a central justification for tighter border controls. During his 2024 campaign, he repeatedly highlighted crimes he said were committed by undocumented immigrants, framing them as a direct threat to American safety. These statements stand in stark contrast to the study’s empirical findings.
Conflicting Reports & Gaps
The study’s robbery finding cannot be definitively linked to victimization because the data do not identify the immigration status of crime victims. Consequently, while the researchers propose a plausible explanation, the hypothesis remains attributed rather than proven. No alternative data sources in the provided material dispute the overall trend of declining property crime and stable violent crime rates.

Implications for Immigration Enforcement
The research suggests that enforcement strategies premised on reducing crime through stricter immigration controls may lack empirical support. By showing no overall crime increase—and even a decline in property offenses—in areas with growing undocumented populations, the study calls into question the public-safety rationale for allocating billions of dollars to immigration enforcement. Policymakers are urged to consider the broader social and economic costs highlighted by the researchers, including community mistrust and adverse effects on families.
