COLLEGE PARK, Md. – The U.S. 'race gap' in the commission of violent crime has narrowed substantially, yet persists in many cities – with murder arrest rates for African Americans out-distancing those for whites – concludes a new 80-city study by the University of Maryland, Florida State University and the University of Oregon.
While the gap had been cut by more than half in the 1970s, it grew again in the '80s with the advent of crack cocaine. The researchers find the gap most pronounced in communities with higher rates of divorce, unemployment and illegal drug use.
