Excellent insight and visualizations from The Guardian:
Looking at the risk of gun homicide in terms of sweeping racial demographics, or even in terms of individual neighborhood census tracts, still obscures the real concentration of violence, crime experts said — and that further concentration is crucial to understanding how to save lives.
Even within high-poverty areas that struggle with many kinds of disadvantage, the majority of residents have nothing to do with gun violence.
Within neighborhood areas, the risk of violence is further clustered within specific social networks of high-risk people. Sometimes these are people whom police identify as gang members; sometimes they are not.
