These data are from the 20-, 15-, and 5-percent samples of the 1970 United States Census of Population and Housing, and contain tabulations of population characteristics such as education, occupation, income, citizenship, and vocational training. Twenty selected geographic summary areas -- including states, counties, standard metropolitan statistical areas, urbanized areas, and places -- constitute the units of observation. Separate tallies are shown for whites, Blacks, Hispanic American (referred to as Spanish Americans in the 1970 Census), and the total population.
