Asians = Chinese in that neck of the woods. There USED to be an urban myth that said that Chinese wouldn’t move into black parts of town. UNTRUE.
For the most part, yes. But there are also many Filipinos, some Koreans and Samoans/Islanders, and people from India. Lots of towns on the peninsula are being changed by an influx of techs from India. They're giving competition to the Chinese in terms of wealth; paying cash for homes. I've seen the number of blacks in SF go from about 15 percent several decades ago to about 6 percent now; they're leaving for cheaper towns away from the inner cities. Their leaving is contributing to improved neighborhoods with less crime. Oakland trails SF, but Asians are taking over there as well (Oakland still needs time to change). Anyway, still some pockets of bad areas in any town, but shrinking around here.
