# Do immigrants increase crime rates in the U.S.? ## 1) Bottom line Across dozens of credible studies, the best available evidence shows that immigrants—both overall and, in most studies, undocumented immigrants—**do not increase crime rates** in the United States. On average, immigrants are **less likely to be arrested, convicted, or incarcerated** than U.S.-born citizens, and places that receive more immigrants tend to see **no change or small declines** in crime. citeturn1search0turn1search3turn0search1turn0search2 --- ## 2) What the strongest evidence says 1) **Long-run national data (incarceration as a proxy for crime).** A National Bureau of Economic Research series compiling 150 years (1870–2020) finds immigrants have **consistently lower incarceration rates** than the U.S.-born; today they are about **60% less likely to be incarcerated** than U.S.-born men. This gap has widened since 1960. citeturn1search0turn1search3 2) **Peer-reviewed meta-review in criminology.** The *Annual Review of Criminology* concludes that most modern, high-quality studies find **null or negative associations** between immigration and crime at the city, county, and state levels. In short: more immigrants ≠ more crime. citeturn0search1turn0search6 3) **Within-state, individual-level evidence on undocumented immigrants.** Analyses of Texas Department of Public Safety records show **undocumented immigrants have substantially lower felony conviction rates** than U.S.-born citizens, and often lower than legal immigrants, across multiple offense categories. (Texas is unusually well-suited because it records immigration status at arrest/conviction.) citeturn0search2 4) **Federal research syntheses.** National Academies briefs summarize a “large body of evidence” that immigrants have **lower crime, arrest, and incarceration rates** than natives; neighborhoods with more immigrants often exhibit **lower crime**, and crime rates among the second generation tend to **converge upward toward native-born levels** over time. citeturn0search9 --- ## 3) Why the association is not positive (leading explanations) - **Positive selection & incentives.** Migrants tend to be positively selected on motivation and risk tolerance for legal work, and face stronger disincentives to offend (e.g., deportation risk). citeturn0search1 - **Community and economic mechanisms.** Immigrant inflows can revitalize local economies and strengthen social controls (family, community organizations), which can modestly **reduce property and violent crime** in some contexts. citeturn0search1 - **Generational dynamics.** The first generation commits less crime; by the second generation, outcomes **move toward native-born levels**, implying assimilation rather than persistent exceptionalism. citeturn0search9 --- ## 4) Important limitations & measurement caveats - **Crime data quality is uneven.** The FBI’s shift from UCR/SRS to **NIBRS** changed coverage and comparability across years and jurisdictions, complicating trend analysis—independent of immigration. Interpret year-to-year changes with caution. citeturn1search5turn1search2 - **“Incarceration ≠ crime.”** Incarceration is a standard proxy but reflects **policing and prosecution** choices as well as offending; nonetheless, the immigrant–native incarceration gap is large, long-standing, and robust across data sources. citeturn1search0 - **Status misclassification.** Studies using immigration status (especially “undocumented”) may suffer from **classification error**; Texas is a notable exception with better status data, but even there authors urge cautious interpretation for minor offenses. citeturn0search2turn0search3 - **Federal prison statistics can mislead.** The federal system houses many offenders for **immigration-specific offenses**, so the share of noncitizens in federal prisons is **not** a valid indicator of violent or property crime propensities. citeturn1search10 - **Local heterogeneity.** Most aggregate studies find null/negative effects, but **short-run local spikes** (e.g., specific neighborhoods, time periods) can occur and merit targeted responses—these do not generalize to a national “immigrant crime wave.” citeturn0search1 --- ## 5) What remains contested or under-studied - **Fine-grained offense categories** (e.g., specific drug markets, organized theft) across many states still lack reliable status-coded microdata. citeturn0search1 - **Causal mechanisms at neighborhood scale**—how exactly immigrant settlement patterns produce small crime reductions (business formation, informal guardianship, housing markets) is not fully pinned down. citeturn0search1 - **Impacts of policy shocks** (e.g., legalization, enforcement surges, or local cooperation with federal authorities) on crime can vary by place and deserve more quasi-experimental evaluation. citeturn0search1 --- ## 6) Expert take Putting the highest-quality evidence together: **No—immigration does not raise U.S. crime rates.** If anything, the association is **neutral to slightly negative**, with first-generation immigrants offending less than natives. Policymaking should therefore be driven by **actual risk patterns** (targeting serious offenders regardless of nativity) rather than assumptions that immigrant presence elevates crime. citeturn1search0turn0search1turn0search2 --- ### Key sources (selected) - Abramitzky, Boustan, & Jácome, NBER working paper: long-run immigrant vs. native incarceration rates (1870–2020). citeturn1search0turn1search3 - Ousey & Kubrin, *Annual Review of Criminology* (2018): synthesis finding null/negative links between immigration and crime. citeturn0search1 - Light & Miller, *PNAS* (2020): undocumented immigrants in Texas show lower felony conviction rates than natives. citeturn0search2 - National Academies (2015 issue brief): immigrants have lower crime; immigrant-dense neighborhoods often have lower crime; second-generation convergence. citeturn0search9 - FBI/NIBRS documentation: cautions on crime data comparability across years/jurisdictions. citeturn1search5turn1search2 *(All sources above are nonpartisan academic or official publications; think-tank analyses were used only when anchored in primary administrative data.)*
