Generate Standard Geography Trade Areas (Business Analyst)

Available with Business Analyst license.


Creates trade areas based on predefined named statistical areas. This tool does not consume credits.


Standard geography trade area


  • Standard geographies are trade areas based on standardized administrative boundaries. In the United States, this includes layers such as states, counties, ZIP Codes, block groups, census tracts, core-based statistical areas (CBSA), designated market areas (DMA), or places. Each country dataset offers administrative boundaries that can vary. Individual trade areas are created for each unique geography—for example, each state, or each ZIP Code that you select.

  • One layer can contain several trade areas—for example, one whole layer containing a collection of counties.

  • The list of IDs must be in a table or list format.

  • The table can be in any format supported by ArcGIS Pro—for example, a comma- or tab-delimited text (.txt) file or Excel file.

  • For the list format, the list of IDs must separated by commas.

  • The geography ID for the entire country trade area is 01.

  • When the Input Type parameter is set to Table, the associated Geography Key Field parameter must be a text field.
