BLS QCEW, 2026Q1

The figures above are County Business Patterns, which carries the size distribution but runs about two years behind. The Bureau of Labor Statistics publishes quarterly, so this is the same industry roughly 3 years later. The two count different universes, Census counts establishments with paid employees in the March pay period and BLS counts worksites covered by unemployment insurance during the quarter, so the numbers are not directly comparable and either can be the larger.

How this market compares

Orange County against every other county in California on the same measure. The median excludes places under 2,000 residents, where per-capita figures are arithmetically true but analytically useless.

Densely served12.5 per 10,000 residents, against a state median of 5.4

Well above the state median for this industry. A crowded market: expect established competitors and price pressure, but also a deeper pool of businesses to buy.

What acquirers look at

California’s corporate practice of medicine doctrine restricts lay ownership, so deals are structured as MSO arrangements. Not a first acquisition for an unlicensed buyer.
