Combining full-count Census data with Census/ACS samples, the researchers provide the first nationally representative long-run series (1870–2020) of incarceration rates for immigrants and the U.S.-born. As a group, immigrants had lower incarceration rates than the US-born for the last 150 years. Moreover, relative to the U.S.-born, immigrants’ incarceration rates have declined since 1960: Immigrants today are 60% less likely to be incarcerated (30% relative to U.S.-born whites). This relative decline occurred among immigrants from all regions and cannot be explained by changes in immigrants’ observable characteristics or immigration policy. Instead, the decline likely reflects immigrants’ resilience to economic shocks.
