I am checking the Federal Public Administration (FPA) across years.
FPA is coded as 916 in the variable IND1950.
Specifically, I want to know FPA across the years from 1910 to 2010. (For 1910-1940 full size, 1950 and 1970 1%, 1960, 1980, 1990, and 2000 5%, and ACS 2000-2019 datasets)
I am interested in definitions of FPA, and the potential changes of its definitions across years.
