Given its relative proximity to East Asia and Southeast Asia, California has the largest number of historic and contemporary Chinatowns in North America. The state boasts of the largest number of Chinatowns of all types, including the most famous Chinatown in San Francisco, the first all-Chinese rural town of Locke to be built by Chinese immigrants, and the first "suburban Chinatown" of Monterey Park.
Many early Chinese immigrants were processed at Angel Island (now a California state park) in the San Francisco Bay area, which is equivalent to New York's Ellis Island for European immigrants.
San Francisco
The largest and most prominent in North America is the San Francisco Chinatown, which is predominantly Cantonese-speaking with some Hakka, though there has been a rise in Mandarin-speaking immigrants from Mainland China. While the downtown Chinatown is the Chinese cultural center, smaller neighborhoods in the Richmond (Geary Avenue, Clement Street) and Sunset (Noriega Street, Irving Street west of 19th Avenue) districts have developed in recent years, coexisting with ethnic Russian and Korean businesses. San Francisco's Chinatown has been shown in numerous movies and television shows. After President Richard M. Nixon's historic visit to the People's Republic of China in the early 1970s, the arrival of new Chinese immigrants to the San Francisco area helped "diversify" and introduce new Chinese cuisine from many regions throughout mainland China in its Chinatown—the restaurants previously served mainly Cantonese and unauthentic Chinese-American fare. It also received many Chinese from Latin America, especially Mexico, Puerto Rico, and Cuba, when Fidel Castro overtook their businesses.
Silicon Valley
Other examples in California are suburban Fremont, Milpitas and Cupertino in the south San Francisco Bay Area. These three cities are located in the Silicon Valley, where large numbers of Taiwanese Americans (i.e., U.S. citizens) and Mainland Chinese nationals (many of whom are on U.S. work visas) are employed in the high-tech industry and where large number of Taiwanese high-tech firms are headquartered. Foster City also has a large Taiwanese American population.
Serving as a major anchor for local area Chinese Americans, the Chinese supermarket chain 99 Ranch Market has played an integral and vital role in the development of some of the suburban Chinatowns in the San Gabriel Valley and Silicon Valley mentioned above.
Oakland
Across from San Francisco, the urban Chinatown of Oakland on Broadway Avenue had existed since the days of the California gold rush but remained economically stagnant for many years. However, this Chinatown saw much development during the 1980s and 1990s after an exodus of Chinese American merchants—who were already experiencing stiff and ever-growing competition and rising costs of rent in the San Francisco area—across the Bay Bridge and increased immigration from mainland China, Hong Kong, Vietnam, Cambodia, and Thailand. Many ethnic Chinese Vietnamese and Chinese Cambodians began opening new small businesses, essentially replacing many of the older Taishanese-dominated businesses. Also, with investment coming from Hong Kong in the 1980s, new modern shopping centers were built. It still retains the traditional aspects and characteristics of an older Chinatown.
Other Asian cultures are represented in Oakland's Chinatown as it has also been settled by non-Chinese Asians such as ethnic Vietnamese (many of whom operate many of Chinatown's jewelry businesses), Koreans, and Thais making it more of a pan-Asian area as opposed to a "Chinatown".
Sacramento
Sacramento has a relatively small urban Chinatown, although it is now comprised mostly of Vietnamese American businesses.
Los Angeles
In the city of Los Angeles proper, the old inner-city Chinatown was built during the late 1930s (indeed, the second Chinatown to be constructed in Los Angeles). Formerly a "Little Italy," it is presently located on Broadway Avenue and Spring Street near Dodger Stadium in downtown Los Angeles. A statue honoring the Kuomintang founder Dr. Sun Yat-sen adorns the more touristy area in the northeast section. A relatively minor satellite Chinatown in Los Angeles is the Lincoln Heights district which is predominantly Latino but also contains a working-class aging Chinese population and recent Vietnamese immigrants.
Orange County
The upscale southern Orange County city of Irvine (爾灣二店), located several miles south of Disneyland, contains yet another Taiwanese-dominant satellite Chinatown. The top-rated University High School and University of California, Irvine (UCI) are major draws for several upper-class Taiwanese immigrant parents. Incidentally, Asian Americans form the majority of UCI's undergraduate student population.
Irvine's Chinese American population has grown significantly over the years. Pao Fa Temple, one of the largest Buddhist temples and monasteries, has been opened.
San Diego
San Diego had a historic Chinatown, formerly around Market Street and Third Avenue, that has disappeared over time. A de facto new "Chinatown" is found about 10 miles away to the north on Clairemont Mesa Boulevard and Convoy Street. Chinatown has also been settled by Chinese from nearby Mexico, especially nearby Mexicali, where Chinese-Mexicans are concentrated.
San Gabriel Valley
In the Greater Los Angeles area, there are several suburban Chinatowns throughout the San Gabriel Valley (see the Asian American communities section of the San Gabriel Valley article for specific streets).
In a sense, the old Chinatown of Los Angeles has ceased to be the economic and cultural node for the local Chinese American community within the Los Angeles area. Within the San Gabriel Valley region, the Mainland Chinese population outnumbers the Taiwanese population at 212,861 to 30,651 as of the 2000 Census, although there are smaller numbers of immigrants from Hong Kong.
The suburban city of Monterey Park (蒙特利公園), nicknamed "Little Taipei," was among the first satellite Chinatowns to be developed and once contained a large Taiwanese population, but due to the in-migration of affluent Taiwanese Americans to other suburbs in the early 1990s, their numbers have dwindled and the Cantonese-speakers have gradually become predominant in the city. For example, there are many more competing large Hong Kong seafood restaurants found within the city than tiny Taiwanese noodle and dumpling restaurants. Since the mid-1980s and on, Monterey Park has experienced continual immigration of working-class and upper-income mainland Chinese and Chinese-Vietnamese. In this city and adjacent areas, the number of Taiwanese-owned supermarkets actually began to decline and many Chinese Vietnamese entrepreneurs have since started ethnic Chinese supermarkets large and small (some of these supermarkets are called sieu thi in Vietnamese). Some notable examples of Chinese Vietnamese-owned supermarket chains include Hong Kong Supermarket and Shun Fat Supermarket and these cater mainly to Pan-Chinese customers.
To the north of Monterey Park, the satellite Chinatown in the city of Alhambra has rapidly grown during the 1980s and it is home to the largest Hong Kong immigrant population within Los Angeles. The neighboring city of San Gabriel (聖蓋博) still has the largest Taiwanese-dominated community in the area (along with the more upscale San Marino and Arcadia), while the "Chinatown" in the city of Los Angeles remains tiny, touristy, and Cantonese-speaking. However, the larger population of Taiwanese and smaller pockets of Cantonese are not actually segregated and they do intermingle and interact in suburbia. In this case, Mandarin remains the lingua franca between these groups. San Gabriel has a population of 13,376 Chinese-descent residents as of the 2000 Census and the city contains a somewhat more vibrant, trendier, and "diverse" satellite Chinatown than Monterey Park with a long row of Taiwanese, Vietnamese, and Hong Kong Chinese businesses. The main thoroughfare of Alhambra and San Gabriel is Valley Boulevard.
Another so-called suburban "Chinatown," so to speak, includes the Taiwanese-driven Rowland Heights (羅蘭崗 - approximately 20 miles east of the Los Angeles Chinatown) with its fragmented smattering of shopping centers. Although there are several large Chinese American populations in nearby residential suburbs, Rowland Heights is the main business district.
