San Gabriel Valley, CA Chinatown
San Gabriel, California "Chinatown"
Chinese communities form a substantial portion of the population of the San Gabriel Valley (simplified Chinese: 圣盖博谷; traditional Chinese: 聖蓋博谷; pinyin: Shèng Gàibó Gǔ). The region has achieved international prominence as a hub of overseas Chinese or hua qiao. Although Chinese immigrants were a noteworthy presence in the establishment of Southern California from the 19th century, significant Chinese migration to suburban San Gabriel Valley coincided with a trend of white out-migration from the 1970s onward. This opened an opportunity for well-educated and affluent Asian Americans to begin settling in the west San Gabriel Valley, primarily to Monterey Park.
High property values and overcrowding in Monterey Park have contributed to a secondary movement away from that city, and the Chinese community is now spread over a cluster of cities in the west San Gabriel Valley. Suburban cities in the valley with large non-white populations, also called ethnoburbs, include Alhambra, Arcadia, Rosemead, San Marino, San Gabriel, South Pasadena, and Temple City and then eastward to Diamond Bar, Hacienda Heights, Rowland Heights, and Walnut. Numerous Mandarin- and Cantonese-speaking businesses have been established in these suburbs to accommodate the changing population. Wikipedia
