Key Research Findings

Analysis of U.S. Census Bureau County Business Patterns data across 831 disclosed U.S. industries reveals 7,186,020 total commercial establishments. Limited-service (fast-food) restaurants rank as America's most common business type with 270,088 establishments, followed by full-service restaurants (258,626) and physician offices (204,617). At the opposite extreme, commuter rail systems rank as the rarest measured industry with just 16 establishments nationwide. An additional 181 industries carry non-disclosed establishment counts in federal CBP reports due to Census confidentiality rules.

1. Background: Measuring Physical Commercial Presence

Under U.S. Census Bureau definitions for County Business Patterns (CBP), a single "establishment" is defined as a single physical location where business is conducted or where services or industrial operations are performed. Unlike legal entities or corporate parent companies (which may own thousands of locations), establishment counts capture the physical footprint of American commerce.

Our study evaluates all 1,012 U.S. 6-digit NAICS industries in data/naics.json. Of these, exactly 831 industries carry disclosed establishment figures totaling 7,186,020 physical locations. The remaining 181 industries carry non-disclosed counts where federal data suppressed numbers to protect individual company confidentiality.

2. America's Top 10 Most Common Industries

Food service, outpatient healthcare, personal legal/real-estate services, and residential trades dominate America's physical landscape. Fast-food and full-service dining combined account for over 528,000 locations nationwide.
