Summary
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 housing characteristics such as housing value, number of housing units in structure, number of rooms in housing unit, year structure was built, occupancy/vacancy status, tenure, rent, type of heating fuel, source of water, and presence of an air conditioner and other home appliances. 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 not tracted in 1970.
