Appendix A: Supplemental Tables

The supplemental tables in this section include distributions at the detailed locale or twelve-locale level. Definitions for these twelve locale codes are provided below; key concepts for these definitions are provided on this page. The supplemental tables are numbered to correspond with their respective indicators.

The new urban-centric classification system has four major locale categories—city, suburban, town, and rural—each of which is subdivided into three subcategories. Cities and suburbs are subdivided into the categories small, midsize, or large; towns and rural areas are subdivided by their proximity to an urbanized area into the categories fringe, distant, or remote. These twelve categories are based on several key concepts that Census uses to define an area's urbanicity: principal city, urbanized area, and urban cluster. A principal city is a city that contains the primary population and economic center of a metropolitan statistical area, which, in turn, is defined as one or more contiguous counties that have a "core" area with a large population nucleus and adjacent communities that are highly integrated economically or socially with the core. Urbanized areas and urban clusters are densely settled "cores" of Census-defined blocks with adjacent densely settled surrounding areas. Core areas with populations of 50,000 or more are designated as urbanized areas; those with populations between 25,000 and 50,000 are designated as urban clusters. For more information on urbanized areas and urban clusters, click here. Rural areas are designated by Census as those areas that do not lie inside an urbanized area or urban cluster.

Several of the following supplemental tables include distributions at the detailed locale or twelve-locale level. Definitions for these twelve locale codes are provided here:

Locale	Definition
City
Large	Territory inside an urbanized area and inside a principal city with population of 250,000 or more
Midsize	Territory inside an urbanized area and inside a principal city with population less than 250,000 and greater than or equal to 100,000
Small	Territory inside an urbanized area and inside a principal city with population less than 100,000
Suburb
Large	Territory outside a principal city and inside an urbanized area with population of 250,000 or more
Midsize	Territory outside a principal city and inside an urbanized area with population less than 250,000 and greater than or equal to 100,000
Small	Territory outside a principal city and inside an urbanized area with population less than 100,000
Town
Fringe	Territory inside an urban cluster that is less than or equal to 10 miles from an urbanized area
Distant	Territory inside an urban cluster that is more than 10 miles and less than or equal to 35 miles from an urbanized area
Remote	Territory inside an urban cluster that is more than 35 miles from an urbanized area
Rural
Fringe	Census-defined rural territory that is less than or equal to 5 miles from an urbanized area, as well as rural territory that is less than or equal to 2.5 miles from an urban cluster
Distant	Census-defined rural territory that is more than 5 miles but less than or equal to 25 miles from an urbanized area, as well as rural territory that is more than 2.5 miles but less than or equal to 10 miles from an urban cluster
Remote	Census-defined rural territory that is more than 25 miles from an urbanized area and is also more than 10 miles from an urban cluster
