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

San Francisco 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 served4.0 per 10,000 residents, against a state median of 1.9

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.

Density compares engineering services provision per resident. It does not measure revenue, profitability or whether a market is worth entering.

Business size mix

San Francisco is more consolidated than California as a whole: fewer micro-operators and a larger share of businesses with real headcount. Fewer targets, but the ones that exist are more likely to be financeable.

What acquirers look at

Value sits in licensed professional engineers and public-agency prequalification, both of which are people-dependent. Retention packages are mandatory.
