Notes:

  • All national files are in compressed format.
  • Files are tab-delimited text, one line per record unless other noted.
  • Data are available for the 50 states, the District of Columbia, and Puerto Rico unless otherwise noted.
  • Population and housing unit counts are not included in these files.
  • The Island Areas (American Samoa, the Commonwealth of the Northern Mariana Islands, Guam, and the U.S. Virgin Islands) are not included in these files.
  • The geography in these files matches the areas for which the 2018 American Community Survey data are published.
  • Because of changes in boundaries and entity names, the creation of new entities, and the dissolution of others, users should not expect a one-to-one relationship between the entity names and codes in these files and the 2012-2017 American Community Survey, 2010 Census, Census 2000, or 1990 Census files.
