BLS QCEW, 2026Q1The 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.

Business size mix
San Diego 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.
| Share of establishments | San Diego | California | Difference |
|---|---|---|---|
| Under 5 employeesOwner-operated, often no management layer | 31.9% | 21.9% | +10.0% |
| 5 to 49 employeesThe range most individual buyers target | 46.8% | 45.5% | +1.3% |

What acquirers look at
Tooling ownership determines customer stickiness. If the customer owns the molds, the revenue can leave overnight. Verify tooling title in diligence.
