By decade’s end, the homicide rate plunged 42 percent nationwide. Violent crime decreased by one-third. What turned into a precipitous decline started later in some areas and took longer in others. But it happened everywhere: in each region of the country, in cities large and small, in rural and urban areas alike. In the Northeast, which reaped the largest benefits, the homicide rate was halved. Murders plummeted by 75 percent in New York City alone as the city entered the new millennium.
