County level homicide rates by race/ethnicity of victim

In my last post, I plotted the overall US county-level homicide rate (all groups combined) by racial/ethnic demographics.  Much of that correlation is being driven by high black-on-black homicide rates throughout the country.

If I plot the rate by the race/ethnicity of the victim this pattern becomes clear and the group-level correlation weaken somewhat (especially asians and whites), but it’s still there…

hom_by_pct_not_white_not_asian_grp_by_re

hom_by_pct_hispanic_grp_by_re hom_by_pct_white_by_re


Since non-hispanic whites are a little hard to see with the combined plots, here are a few with whites split out:

minimum population size >= 10K (r=0.29)
nhw_homicide_rate_by_pct_black_weighted_regressionminimum population size >= 100K (r=0.39)

nhw_homicide_rate_by_pct_black_weighted_regression_100K

Some of this may be driven by underlying regional patterns (a question for a follow up post maybe), but there’s a fairly strong correlation and there are good reasons to think there is a causal relationship driving at least some of the observed relationships (also see similar patterns with asians above).

That’s it for now.
