Abstract

The United States experienced a dramatic decline in crime during the 1990s. A number of explanations for this decline have been put forth, including demographic shifts, economic trends, stricter gun control laws, and changes in drug markets. A widely reported explanation is that the surge of immigration during the 1990s was the main cause for that decade's crime decline. Although the claim has received considerable attention, it has yet to be tested empirically using national-level data. In order to fully test the immigration-1990s crime decline relationship, we use national-level homicide and Census data from 1990 to 2000. Our results reveal four key findings: (1) crime declined for nearly all groups during the 1990s; (2) non-Latino blacks contributed the most to the crime decline, by a wide margin; (3) both overall and black homicide declined the least in areas with the highest levels of immigration; and (4) we find no evidence that immigration indirectly lowered non-immigrant crime rates by revitalizing communities. We conclude by discussing the implications of our findings.
