San Francisco is the traditional focal point of the San Francisco Bay Area and forms part of the five-county San Francisco–Oakland–Hayward, CA Metropolitan Statistical Area, a region of 4.6 million people. It is also part of the greater 12-county San Jose-San Francisco-Oakland, CA Combined Statistical Area, whose population is over 8.75 million, making it the fifth-largest in the United States as of July 1, 2016.  The U.S. Census Bureau estimates San Francisco's population increased to 870,887 as of July 1, 2016.

San Francisco has a minority-majority population, as non-Hispanic whites comprise less than half of the population, 41.9%, down from 92.5% in 1940.  The principal Hispanic groups in the city were those of Mexican (7.4%), Salvadoran (2.0%), Nicaraguan (0.9%), Guatemalan (0.8%), and Puerto Rican (0.5%), ancestry. The Hispanic population is most heavily concentrated in the Mission District, Tenderloin District, and Excelsior District.  San Francisco's African American population has declined in recent decades,  from 13.4% of the population in 1970 to 6.1% in 2010.  The current percentage of African Americans in San Francisco is similar to that of the state of California;  conversely, the city's percentage of Hispanic residents is less than half of that of the state. The majority of the city's black population reside within the neighborhoods of Bayview-Hunters Point, and Visitacion Valley in southeastern San Francisco, and in the Fillmore District in the northeastern part of the city. 
In 2010, residents of Chinese ethnicity constituted the largest single ethnic minority group in San Francisco at 21.4% of the population; the other Asian groups are Filipinos (4.5%), Vietnamese (1.6%), Japanese (1.3%), Asian Indians (1.2%), Koreans (1.2%), Thais (0.3%), Burmese (0.2%), Cambodians (0.2%), and Indonesians, Laotians, and Mongolians make up less than 0.1% of the city's population.  The population of Chinese ancestry is most heavily concentrated in Chinatown, Sunset District, and Richmond District, whereas Filipinos are most concentrated in the Crocker-Amazon (which is contiguous with the Filipino community of Daly City, which has one of the highest concentrations of Filipinos in North America), as well as in SoMa.
After declining in the 1970s and 1980s, the Filipino community in the city has experienced a significant resurgence. The San Francisco Bay Area is home to over 382,950 Filipino Americans, one of the largest communities of Filipinos outside of the Philippines.   The Tenderloin District is home to a large portion of the city's Vietnamese population as well as businesses and restaurants, which is known as the city's Little Saigon. Koreans and Japanese have a large presence in the Western Addition, which is where the city's Japantown is located. The Pacific Islander population is 0.4% (0.8% including those with partial ancestry). Over half of the Pacific Islander population is of Samoan descent, with residence in the Bayview-Hunters Point and Visitacion Valley areas; Pacific Islanders make up more than three percent of the population in both communities. 
Native-born Californians form a relatively small percentage of the city's population: only 37.7% of its residents were born in California, while 25.2% were born in a different U.S. state. More than a third of city residents (35.6%) were born outside the United States.

San Francisco ranks third of American cities in median household income  with a 2007 value of $65,519.  Median family income is $81,136,  and San Francisco ranks 8th of major cities worldwide in the number of billionaires known to be living within city limits.  Following a national trend, an emigration of middle-class families is contributing to widening income disparity  and has left the city with a lower proportion of children, 14.5%, than any other large American city. 
The city's poverty rate is 11.8% and the number of families in poverty stands at 7.4%, both lower than the national average.  The unemployment rate stands at 4.8% in the greater San Francisco Bay Area as of January 2015 [update]. 
Homelessness has been a chronic and controversial problem for San Francisco since the early 1970s when many mentally ill patients were deinstitutionalized, due to changes which began during the 1960s with the enactment of Medicare and Medicaid.  The homeless population is estimated to be 13,500 with 6,500 living on the streets.  The city is believed to have the highest number of homeless inhabitants per capita of any major U.S. city.   Rates of reported violent and property crimes for 2009 (736 and 4,262 incidents per 100,000 residents, respectively)  are slightly lower than for similarly sized U.S. cities.
