The shapefile format was originally defined for use in Esri GIS applications, but the format has become an industry standard, and many GIS and mapping tools are able to read and write shapefile data. NHGIS generally identifies each GIS file by the survey year in which the file's represented areas were used for tabulations, which may be different than the vintage of the represented areas. For example:. This Census Bureau page identifies the vintages of geographic areas for each ACS survey year since NHGIS identifies these boundaries with , not , because they correspond to the boundaries of census units and are not completely consistent with the units identified in ACS tables.

In Louisiana, these divisions are known as parishes. In Alaska, which has no counties, the equivalent entities are the organized boroughs, city and boroughs, municipalities, and for the unorganized area, census areas. The latter are delineated cooperatively for statistical purposes by the State of Alaska and the Census Bureau. In four states Maryland, Missouri, Nevada, and Virginia , there are one or more incorporated places that are independent of any county organization and thus constitute primary divisions of their states. These incorporated places are known as independent cities and are treated as equivalent entities for purposes of data presentation. The District of Columbia and Guam have no primary divisions, and each area is considered an equivalent entity for purposes of data presentation.
