Census Tract Distance Database

Census Tract Distances are great-circle distances calculated using the Haversine formula based on internal points in the geographic area.

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.

Updates and changes.
