How this market compares
Modesto 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.
A larger slice of the local business base than the statewide share. Usually a sign of genuine local demand rather than oversupply.
