The Center for Immigration Studies used crime victimization data to look at how often crimes were reported by Hispanics versus non-Hispanics, and more precisely for the immigration context, how often crimes were reported by citizens and non-citizens.

For example, Hispanic immigrants, both citizens and non-citizens, reported 65% of serious violent crimes from 2017 to 2019, compared to just 49% of native-born.

In early 2017, for example, Los Angeles reported seeing a major drop in Hispanic crime reporting of sexual assaults and domestic violence over the first two months of the Trump administration, which city officials attributed to people being scared of deportation.

California then enacted a series of statewide sanctuary policies that took effect in 2018, which under Los Angeles’ theory of crime reporting should have led to a spike in Hispanic reports of crimes.

The crime victimization data used by CIS for the new analysis is a survey taken by the Census Bureau on behalf of the Justice Department.

Among the findings were that 62% of serious crimes against immigrants — both legally and illegally present — were reported to police, compared to 53% for the native-born population

For violent crimes, immigrants reported 61%, compared to 49% for the native-born

The CIS analysis used Hispanic non-citizens as a rough proxy for illegal immigrants and found even among that population, there wasn’t a major difference in reporting compared to native-born Americans

Another study released in January used the same victimization data as CIS and found that Hispanic crime reporting seemed to drop in 2017, when the Trump administration took over
