The Brennan Center reported that the 2018 murder rate in the 30 largest American cities was estimated to have declined by nearly six percent overall, in part because of large decreases in Chicago and San Francisco (18.1 percent and almost 27 percent, respectively).
Houston, Philadelphia and Washington, D.C.
These cities are outliers in an otherwise national decline of murder rates in America. The Brennan Center predicts D.C.'s homicides will climb 39.5 percent this year, while Houston's are expected to grow another 22.6 percent in 2019.
Violent crime rates and overall crime rates fell across the nation in keeping with decades-long trends, even in those cities that saw increases in their homicide rates.
But while previous spikes in D.C. homicides like the one in 2015 had clearer explanations (like high economic inequality and poverty), 2018's rise in murders left many of experts baffled.
