==== Ethnic clustering ====
San Francisco has several prominent Chinese, Mexican, and Filipino neighborhoods including [[Chinatown, San Francisco|Chinatown]] and [[Mission District, San Francisco|the Mission District]]. Research collected on the immigrant clusters in the city show that more than half of the Asian population in San Francisco is either Chinese-born (40.3%) or Philippine-born (13.1%), and of the Mexican population 21% were Mexican-born, meaning these are people who recently immigrated to the United States.<ref name=":02">{{Cite journal|last=Pamuk|first=Ayse|date=Fall 2017|title=Geography of immigrant clusters in global cities: a case study of San Francisco|journal=International Journal of Urban and Regional Research|volume=28|issue=2|pages=287–307|doi=10.1111/j.0309-1317.2004.00520.x}}</ref> Between the years of 1990 and 2000, the number of foreign-born residents increased from 33% to nearly 40%.<ref name=":02"/> During this same time period, the San Francisco metropolitan area received 850,000 immigrants, ranking third in the United States after Los Angeles and New York.<ref name=":02"/>
