How this market compares

Ontario 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.

Densely served0.18% of local businesses, against 0.02% statewide

This industry takes up a far larger slice of the local business base than it does statewide. A crowded market: expect established competitors and price pressure, but also a deeper pool of businesses to buy.
