2011 is the most recent year for which we have the most crime data for our range of cities in the Southern California region from the Southern California Crime Study. The 1/2 mile radius represents the common distance people will walk to various amenities. A 2-mile radius is useful since it gives a broader perspective (e.g., of where people drive) so the two can be compared. Currently, we do not have crime data for every single city in the Southern California region (although we have the majority of cities).The cities for which we have crime data are outlined in blue.
