In California, are certain counties more friendly to small businesses than others? To pinpoint the areas where small businesses abound, altLINE used Census Bureau data to find the counties in California with the highest concentration of small businesses in 2021, calculated as small establishments per 1,000 residents. Small establishments are defined as those with fewer than 500 employees. Counties with fewer than 1,000 residents were excluded from the analysis, as well as counties for which the Census Bureau didn’t have population estimates.
