The report identifies the most segregated neighborhoods of white wealth in the Bay Area; Alamo ranks 15th | New

The index is calculated by subtracting the number of low-income Black, Latino, or Asian American/Pacific Islander households from the number of high-income white households and dividing by the total number of households in a census tract.

Using this method, the report identifies Belvedere in Marin County and Woodside in San Mateo County as having two of the most segregated neighborhoods in the Bay Area in terms of white wealth.

“In these two areas, there are no black or Latino households with incomes below $45,000 and only a handful of low-income AAPI households, but there are over 100 low-income white households in each census tract, casting doubt on purely income-based segregation explanations,” according to the report.

Every county in the Bay Area except Sonoma and Solano is home to at least one highly segregated white wealth neighborhood.

Some of the census tracts identified in the report as being among the 20 most segregated are in Piedmont in Alameda County, Alamo in Contra Costa County (ranked 15th), Monte Sereno in Santa Clara County, and the whole town of Orinda to Contra Costa.
