"Traffic Stop Data Can Shape Policy. It’s Often Missing."

From The New York Times:

Last Monday, we published a data-driven look at the decline of traffic stops in America. The cities and states we highlighted weren’t necessarily those with the steepest declines in traffic enforcement nationally — they were places with steep declines that data enabled us to see.

There is no national standard or source for recording traffic stops, so we tried to gather data from as many different cities and state agencies as possible. Many cities we would have liked to have shown had incomplete data.
