How this market compares

Concord against every other city in California on the same measure. City figures cover the ZIP codes assigned to the place rather than its municipal boundary, so they are compared as a share of the businesses in those same ZIP codes rather than per resident. Cities with fewer than 500 businesses in total are left unranked.

Below average1.75% of local businesses, against 2.85% statewide

A smaller slice of the local business base than the statewide share. Often an underserved market, though it can also mean the work is done by firms based in a neighbouring town.

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.
