A Growing Divide in Urban Gun Violence

The places way above the line for gun murders, like Detroit, Baltimore, Philadelphia, New Orleans, Newark, St. Louis, and Chicago, all have large, very segregated black communities with a history of disinvestment, outmigration, and, except for Chicago, not big immigration in recent decades. With the exception of the South Bronx, New York never had demographic collapse on the same scale. What the Detroit's and Baltimore's of American cities also had was extremely high concentrated poverty that mapped onto race.

There are quite a number of cities — Chicago, Detroit, New Orleans, Los Angeles, Houston, Phoenix, Philadelphia, Baltimore, Miami, and others — which are far above the line.
