A radius report is a report that shows cumulative demographic data for a circular area around a given location. The size of the circle is determined by a given radius. Our reports show data for 3 different circular areas, based on 3 different radius values, around a given location. Our standard-radius report shows data for 1-mile, 3-mile and 5-mile radius values. Our custom-radius report allows you to specify the 3 radius values, from a quarter mile to 100 miles.
