Police killings occur very disproportionately in high-poverty tracts and that this is true across all racial groups.

From New York State of mailbag by Matthew Yglesias.

Chris Brandow: Have you read or investigated the relationship between police shootings and income of suspects, rather than simple racial identities. Obviously income and race are related, but I wonder how significant the racial disparities are between lower income suspects.

The individual-level data on income does not seem to exist, so when Justin Feldman looked at this, he looked at tract-level poverty rates from the census and found that police killings occur very disproportionately in high-poverty tracts and that this is true across all racial groups.
