County Distance Database

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

Counties are from Census 2000 SF1 and Census 2010 SF1 files. The county codes are FIPS County codes. The first two digits of the FIPS county codes are FIPS State codes.

Jean Roth created the SAS, Stata, and CSV distance files to make the data easier to use.

The size of the file increases with the radius. Smaller files (<= 25 or <= 50 miles) may be easier to use if only County distances <= 25 or <= 50 miles respectively are needed. The has all combinations of counties.

Updates and changes.
