Spreadsheets and statistical software can read the comma-separated CSV file. The Stata .dta file can be converted to other formats using conversion software such as Stat/Transfer.

Single year U.S. county population data is available for 1969-on from Survey of Epidemiology and End Results (SEER)

The University of Virginia Library's Geostat Center is another source of pre-1969 county population data. They created electronic versions of the 1944-on County and City Data Books. These have county population estimates for 1930, 1940, 1943, 1950, 1960.

Paper sources for pre-1969 data include Census Report P25-427 "Estimates of the population of counties and metropolitan areas, July 1, 1966",and P25-461 "Components of population change by county: 1960 to 1970".
