Soon a Chinese majority and Caucasian minority. Blacks have been moving out for several years and now Mexicans are doing likewise as Asians ( mostly from communist China ) are buying up most of the housing ( both in SF city proper and in the suburbs). There’s still a tremendous amount of diversity in SF! But it’s clear that the Asians are buying up more and more of it. Incidentally the suburban country immediately to the south was declared America’s most diverse county a couple years ago by the US Census Bureau And its housing is largely being bought up by people in or from Communist China, too ) More and more Asians, including Vietnamese Koreans etc. lots of diversity among the Asians if you look closely but we don’t know if the survey measures that?
You mean San Mateo County? Santa Clara County is roughly 1/3 white, 1/3 Asian, 1/3 Hispanic, with 2% or less black.
