Abstract: Summary Tape File 4 consists of three sets of computer-readable data files containing highly detailed tabulations of the nation's population and housing characteristics produced from the 1980 census. The files contain sample data inflated to represent the total United States population. The files also contain 100% counts and unweighted sample counts of persons and housing units. This series is comprised of STF4A, STF4B, and STF4C. All three series have identical tables and format. Population items tabulated for each area include demographic data and information on schooling, ethnicity, labor force status, children, and details about occupation and income. Housing items include data on size and condition of the housing unit as well as information on value, age, water, sewage and heating, vehicles, and monthly owner costs. ICPSR has acquired an 'extract' of STF4B. All geographical entities from the complete STF4B series are included in the extract file for each state, along with the seven major 'record types' out of a possible total of 39. The record types in the extract file each represent a population group for which the detailed tabulations were presented. Included are record types for Total Population, White Population, Black Population, American Indian, Eskimo and Aleut Population, Asian and Pacific Islander Population, Other Races Population, and Spanish Origin Population. The STF4B geographic entities for which all STF4 data items are tabulated and reported for the above groups in this extract are as follows: State (along with numerous rural, urban and SMSA components of each state), SCSAs (Standard Consolidated Statistical Areas), SMSAs, Urbanized Areas, All Counties and County Equivalents (along with rural and rural-farm components of counties), MCD/CCDs, Places of 2,500+ Population, and American Indian Reservations/Alaska Native Villages (and county components of American Indian Reservations). Each logical 'record' in these files is comprised of 86,064 characters. For each record there are 44 record segments (physical records) of 1,956 characters each. These numbers represent the amount of data in a geographical area for each record type. Thus the total amount of data available for a given geographical area may be seven times as high as these numbers, if all the record types are present for that area. The number of data records varies by state. Data for all 51 states and the District of Columbia are now available.
