10200-571: The city, according to the National Register of Historic Places listings in San Francisco . San Francisco is located on the West Coast of the United States , at the north end of the San Francisco Peninsula and includes significant stretches of the Pacific Ocean and San Francisco Bay within its boundaries.

While people residing outside the San Francisco Bay Area use nicknames including "Frisco" and "San Fran", local residents in the Bay Area sometimes refer to San Francisco as "the City" or "SF".

"San Fran" and "Frisco" are sometimes considered controversial as nicknames among San Francisco residents. The earliest archeological evidence of human habitation of
10472-432: The city. Also included are the uninhabited Farallon Islands , 27 miles (43 km) offshore in the Pacific Ocean.

There are more than 50 hills within the city limits. Some neighborhoods are named after

John Marsh , owner of Rancho Los Meganos in Contra Costa County, sent letters to influential people in
10744-515: The country at the time. His financial empire, however, collapsed in 1875 as a result of the Panic of 1873 , triggering a major economic crisis in San Francisco.

Layers of volcanic ash ejected from geologically recent but now extinct volcanoes , compacted and now tilted by compressive forces, may be seen at the site of some road excavations. This county is an agglomeration of several distinct geologic terranes , as is most of
11016-482: The county is the 3,849-foot (1,173 m) Mount Diablo , at the northerly end of the Diablo Range . Mount Diablo and its neighboring North Peak are the centerpiece of Mt.

In the 1960s, suburban development expanding from

The effects of the housing value crash (2008–2011) varied widely throughout the county. Values of houses in prosperous areas with good schools declined only modestly in value, while houses recently built in outlying suburbs in
11288-628: The development of West Portal , and nearby affluent Forest Hill and St. Francis Wood . Further west, stretching all the way to the Pacific Ocean and north to Golden Gate Park lies the vast Sunset District , a large middle-class area with a predominantly Asian population. The northwestern quadrant of the city contains the Richmond , a mostly middle-class neighborhood north of Golden Gate Park, home to immigrants from other parts of Asia as well as many Russian and Ukrainian immigrants. Together, these areas are known as The Avenues . These two districts are each sometimes further divided into two regions:
11424-412: The development of canals that brought water from the eastern riverside portions of the county to the central portion. Other areas could use the more limited water available from local creeks and from wells.

11696-467: The eastern part of the county experienced severe reductions in value, accelerated by high unemployment and consequent mortgage foreclosures, owner strategic walk-aways , and the too-rapid conversion of neighborhoods from owner-occupancy to rentals.

11968-774: The excavation of the Yerba Buena Tunnel through Yerba Buena Island during the construction of the Bay Bridge. Such land tends to be unstable during earthquakes.

Younger deposits at middle altitudes include pillow lavas ,

13192-538: The larger Port of Oakland . The city began to lose industrial jobs and turned to tourism as the most important segment of its economy. The suburbs experienced rapid growth, and San Francisco underwent significant demographic change, as large segments of the white population left the city, supplanted by an increasing wave of immigration from Asia and Latin America. From 1950 to 1980, the city lost over 10 percent of its population. Over this period, San Francisco became
