Census U.S. Decennial County Population Data, 1900-1990
The Census Bureau created an excellent resource for historic U.S. decennial population at the level of the state or county for each Census year from 1900-1990.
The text file created by Richard Forstall was modified by data@nber.org to make a .csv file of decennial population data that is easier to find and 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...".
