Most Diverse Neighborhoods On the West Coast
Published:
The third most populous country, the United States is also one of the more ethnically and racially diverse countries in the world. Of course, not all parts are as equally diverse, and some states, some cities, even some neighborhoods are more diverse than others. To help represent diversity of an area, the Census Bureau has created a measure that calculates the chance that two people chosen at random from a certain place will be from different race and ethnicity groups.
To determine the most diverse neighborhoods on the West Coast, 24/7 Wall St. calculated this measure for different census tracts, using five-year data on race and ethnicity from the U.S. Census Bureau’s 2022 American Community Survey. Neighborhoods were ranked based on the probability that two residents picked at random will be of different race or ethnicity. Racial and ethnic groups include white, Black or African American, American Indian and Alaska Native, Asian, Native Hawaiian and other Pacific Islander, Hispanic or Latino, some other race alone, and two or more races.
It may be surprising considering that it is the second most populous metropolitan area nationwide, but only one neighborhood in Los Angeles is on the list — Downtown LA. However, neighborhoods in cities in the Bay Area constitute a large portion of the list. This includes 14 neighborhoods in Sacramento, eight in Oakland, and a few more in nearby cities. In all, 39 neighborhoods are in California, eight in Washington state, and three in Alaska, including the two most diverse on the list. (Also see: The Most Diverse Neighborhoods On the East Coast.)
Among the most diverse neighborhoods, housing tends to be expensive, with home values generally above the U.S. typical home value in November 2023 of $342,099. Of the 47 neighborhoods with housing value data, only five have lower home values. Meanwhile, two neighborhoods, one in Hayward, California, and one in San Francisco, have home values of over a million.
To determine the most diverse neighborhoods on the West Coast, 24/7 Wall St. reviewed five-year data on race and ethnicity from the U.S. Census Bureau’s 2022 American Community Survey. The probability that any two residents picked at random will belong to a different racial or ethnic category is equivalent to the sum of the squares of each group’s share of the population, subtracted from 1. The same method is used in the USA Today Diversity Index as well as the racial and ethnic diversity index of the Disseminating Diversity Working Group of the Census Bureau.
Data on population by race and ethnicity were aggregated from the census tract level to the neighborhood level using 2022 census tract boundary definitions from the U.S. Census Bureau and 2017 neighborhood boundary definitions from Zillow. Census tracts with at least 50% spatial overlap within the neighborhood boundary were included in population aggregation. Data on estimated median home value is the November 2023 Zillow Home Value Index, a measure of typical home values for homes in the 35th to 65th percentile range.
