"We don't really have a common definition of what crime means, when you ask that question," says Jeff Asher, a data analyst who specializes in crime statistics. Most big cities tend to produce and make crime data available in some format in "near-real time," so that people can see numbers from the last few weeks, months or quarter, he explains, adding that smaller cities, suburbs and sheriff's offices don't necessarily make it as accessible. This year, the FBI changed the way it collects crime data — and many of the nation's roughly 18,000 law enforcement agencies were slow to get on board.
