A large-scale study published in the Journal of Urban Affairs has found no link between undocumented immigration and increased crime rates in the United States. The research, led by Charis E. Kubrin of the University of California, Irvine, and co-authored by researchers from Stanford University and the University of Akron, analyzed 11,500 neighborhoods representing approximately 46 million residents between 2010 and 2018. The findings indicate that neighborhoods with a growing share of undocumented residents experienced greater reductions in property crimes and saw no significant changes in violent crime rates. Researchers emphasized that previous studies often failed to differentiate between various legal statuses, a distinction they consider vital because legal status affects access to employment and social support. One researcher noted that this empirical evidence challenges long-standing public perceptions, drawing a comparison to the 1930s Wickersham Commission report which also found lower crime involvement among immigrants than native-born citizens. By utilizing U.S. Census and National Incident-Based Reporting System ~~data,~~ data across more than 100 cities, the study provides a national sample to challenge public perceptions regarding the relationship between immigration status and criminal activity. The research highlights that while 2023 estimates suggest 27% of immigrants in the U.S. are undocumented, the presence of these residents was not associated with a rise in criminal activity, but rather showed a downward trend in crime rates in the studied municipalities.
