Are US cities getting more or less violent? New database offers mixed picture

According to a new analysis by New York University researchers, US cities have become dramatically safer since 1991, with most becoming less violent over the last year. However, recent fluctuations in selected cities suggest temporary disruptions in this 17-year decline, with some cities experiencing rising violence from 2014 to 2017.
