Census U.S. Intercensal County Population Data, 1970-2014

The Census Bureau's Population Estimates Program publishes population estimates each year.

The 1970s, 1980s, 1990s, 2000s, and 2010s files were modified to make a single .csv file of county and state intercensal population data that is easier use.

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.

To download files in Internet Explorer, right click on them and select Save Target As....

Updates and changes.

National data users might find the national-level file easier to work with:
