Summary File 1

Demographic data down to the block level!

Availability: Summary File 1 is available on disc in two different file formats. The software version contains retrieval software allowing users to manipulate, display, and download data from the file. The files also come in an ASCII version. In addition, the file is available in the American Fact Finder and in ASCII format through FTP.

Software Version:

  1. U.S. Summary. DVD containing all the substate data in Summary File 1 file (V1-D00-S1S1-08-US1). Geography: states, metropolitan statistical areas (1999 definitions), counties, county subdivisions, places (i.e., cities and census designated places), ZIP Code Tabulation Areas®, congressional districts (106th Congress), American Indian and Alaska Native Areas, Hawaiian Home Lands, census tracts, census block groups, and census blocks. Note: the file has data for the state parts of geographical areas that are in more than one state (e.g., American Indian reservations and metro areas); users would have to download the parts and total them. File also includes one-page profiles of most geographic areas.
  2. State files. CD-ROMs containing Summary File 1 data for individual states on one or more discs. Geography: state, metropolitan statistical areas (1999 definitions), counties, county subdivisions, places (i.e., cities and census designated places), ZIP Code Tabulation Areas®, congressional districts (106th Congress), American Indian and Alaska Native Areas, Hawaiian Home Lands, census tracts, census block groups, and census blocks. Note: the state file has data for the parts of geographical areas that are within the state (e.g., American Indian reservations and metro areas) and does not include the parts found in other states. File also includes one-page profiles of most geographic areas. (See listing below for product IDs)
  3. National file. One DVD containing Summary File 1 data for larger geographic areas (V1-D00-S1ST-08-NAT1). Geography: United States, regions, divisions, states, counties, county subdivisions, places (i.e., cities and census designated places), metropolitan statistical areas, ZIP Code Tabulation Areas®, congressional districts (106th Congress), American Indian and Alaska Native Areas, and Hawaiian Home Lands. Users needing totals for geographical areas that are in more than one state (e.g., American Indian reservations and metro areas) will find them easier to obtain from this file than from the U.S. Summary file (see above).
