Sources: County Business Patterns (2023); Nonemployer Statistics (2024).

  • Residents per establishment is the place's population estimate for 2023 divided by its establishments; more residents per business means fewer competitors per resident. Places with fewer than the minimum establishments are left out because a handful of businesses makes the ratio jump around.
  • Metro areas are made of whole counties and their figures are the exact sums of those counties'. A metro area is listed under its principal state.
  • This compares counts of businesses with counts of residents. It does not measure demand, spending power, visitors, the size or quality of the businesses, or whether a market is open. Employment and payroll carry the Census Bureau's noise infusion.
  • County Business Patterns 2023 uses NAICS 2017 codes; the nonemployer figures use NAICS 2022. Industries are matched by name between editions.
  • Growth needs a second reference year of County Business Patterns in the same industry classification; only 2023 is loaded, so there is no growth column yet.

Where the work was performed, as agencies report it (often the contractor's office). Metro areas are the exact sums of their counties. Cities are estimated: each action's county money split by the share of its ZIP code's land inside the city, so a city's figure is part of its county's.
