Census Tracts are from Census 2000 SF1 and Census 2010 SF1 files. Census Tracts are "small, relatively permanent statistical subdivisions of a county or equivalent entity".
The size of the file increases with the radius. Smaller files (<= 1 or <= 5 miles) may be easier to use if only distances <= 1 or <= 5 miles respectively are needed.
