Census of Population and Housing, 1990 [United States]: Summary Tape File 4B (ICPSR 6271)
Summary Tape File 4B contains sample data weighted to represent the total United States population. The collection also contains 100-percent counts and unweighted sample counts for total persons and total housing units. Additional population and housing variables include items such as age, ancestry, disability, citizenship, education, income, marital status, race, sex, travel time to work, hours worked, rent, persons in household, acreage of property, tenure, value of housing unit, number of vehicles, and monthly owner costs. Data are provided for states (and the District of Columbia) and their county subareas. Within STF 4B, data for each state are represented in one "A" record file and 49 "B" record files. The "A" records contain 123 population tables and 80 housing tables. These include five population tables and one housing table showing 37 categories of race and five population tables and one housing table with 26 categories of Hispanic origin. Data are included for all persons for each summary level and geographic component level within a unit of geography. More detailed data are presented in 178 population and 85 housing tables in the "B" records. The "B" records include a separate file for all persons and up to 48 separate race and Hispanic-origin files.
