Summary

These data are from the 20-, 15-, and 5-percent samples of the 1970 United States Census of Population and Housing, and contain population characteristics such as education, occupation, income, citizenship, and vocational training. Separate tallies are shown for whites, Blacks, Hispanic Americans (referred to as Spanish Americans in the 1970 Census), and the total population. The unit of observation for these data files is the census tract. There is one file for each of 48 states and the District of Columbia. The Census Bureau did not issue data for Vermont and Wyoming because these two states were untracted in 1970.
