Yep, the fact that immigrants commit less crime than native-born citizens has been known since Herbert Hoover established the Wickersham Commission in 1929. What makes this study uniquely important is its methodology.

To estimate the undocumented population at the neighborhood level, the research team accessed restricted individual-level Census data through a federal Research Data Center (RDC) and then applied an imputation method similar to those used by the Department of Homeland Security.

This is where they relied on the expertise of Christopher, who received his training at UC Irvine, earning an economics Ph.D. in 2022 before joining Stanford.

Christopher is one of the few academic researchers to have published work leveraging such a method.
