| Summary: | Summary Tape File 420 (STF 420) contains sample data weighted to represent the total population of workers 16 years old and over as well as 100-percent counts of all persons and housing units. Included are five population tables and one housing table for each state and its subareas in hierarchical sequences down to the census tract/block numbering area (BNA) level. For workers 16 years old and over, data for 20 places of work and for those working elsewhere are provided for five race groups: (1) White, (2) Black, (3) American Indian, Eskimo, or Aleut, (4) Asian or Pacific Islander, (5) other race and Hispanic origin by race. In addition, a supplemental file, Part 80, is provided that includes a machine-readable list of the total number of workers living in each county and, for that county, the number of persons working in the 20 destinations listed as well as a "worked elsewhere" category for the remainder of places worked. The list also applies to the sub-county geographic units (census tracts/BNAs) and contains a variety of geographic entities as destinations (the number of destinations may be less than 20).
