Scout's crime data are the most recent ‘Final, non-preliminary’ data available. Sometimes a city law enforcement agency will post preliminary data to its website which would not match our data. Other times, cities only show year-to-date crimes, which by their nature, are only for a partial year; for example only January - September.
Also, our data are for the city overall, not just from a single law enforcement agency in the city. FBI reporting is agency-focused and only shows crimes by agency. Similarly, individual city agencies will almost always show only the crimes from their single agency, not for all agencies that have law enforcement responsibility in the city.
Our analysis includes all crimes reported by every agency in a city, and is therefore much more comprehensive.
