California Counties and the States they Resemble

Posted on January 10, 2019 at 10:51 AM by Summer Anderson

Few states compare to California's racial and ethnic diversity. Within California, though, some counties more closely resemble some of the other 49 states. The map illustrates counties' closest state matches, based on calculating the cosine similarity of states' and counties' racial and ethnic make-ups. Click here to learn more about cosine similarity. Source: 2012-2016 American Community Survey 5-year estimates. Please visit the California Department of Finance website to interact with this map and read about all of the counties in California!

Please see the Race/Ethnicity table below to understand California percentages as compared to San Joaquin County.

Note: the race/ethnic distributions used in the calculation include the population in group quarters (or GQ, denoting shared living arrangements). In some counties, the demography of the GQ population is significantly different than the population in households, which affects the comparison in cases where a significant proportion of the county's total population lives in GQ.
