This thematic map shows the Sunset District's large Asian American population in western San Francisco.
Originally, Noriega Street was called "N Street" as it was part of a sequence that had letters A-W, with H Street being called Lincoln Street. The original residents were almost exclusively European until the 1970s when "people of color" started moving in. Today, the Chinatown is part of the district where people of Chinese descent are the largest group. The name "Noriega Street" was named after a Spanish soldier and former commander of the Monterey Presidio. As of recent, the "... businesses are predominantly Asian."
