The Chinatown centered on Grant Avenue and Stockton Street in San Francisco, California, is the oldest Chinatown in North America and the largest Chinese enclave outside Asia. It is the oldest of the four notable Chinatowns in the city. Since its establishment in 1848, it has been highly important and influential in the history and culture of ethnic Chinese immigrants in North America. Chinatown is an enclave that continues to retain its own customs, languages, places of worship, social clubs, and identity.[from wikipedia]

The area was the one geographical region deeded by the city government and private property owners which allowed Chinese persons to inherit and inhabit dwellings within the city. The majority of these Chinese shopkeepers, restaurant owners, and hired workers in San Francisco Chinatown were predominantly Hoisanese and male.[from wikipedia]
