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.

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

Business size mix

Mariposa is more fragmented than California as a whole: a larger share of very small operators. Fragmented markets are where roll-ups are assembled, and where an owner nearing retirement has no obvious internal buyer.

What acquirers look at

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