In 2019, San Francisco was the county with the seventh-highest income in the United States, with a per capita income of $139,405.[24] In the same year, San Francisco proper had a GDP of $203.5 billion, and a GDP per capita of $230,829.[21][25] The San Jose–San Francisco–Oakland, CA Combined Statistical Area, with a GDP of $1.09 trillion as of 2019, is the country's third-largest economy.[26] Of the 105 primary statistical areas in the U.S. with over 500,000 residents, this CSA had the highest GDP per capita in 2019, at $112,348.[26] San Francisco was ranked 5th in the world and second in the United States on the Global Financial Centres Index as of September 2021.[27]

San Francisco was founded on June 29, 1776, when colonists from Spain established the Presidio of San Francisco at the Golden Gate and Mission San Francisco de Asís a few miles away, both named for Francis of Assisi.[3] The California Gold Rush of 1849 brought rapid growth, transforming an unimportant hamlet into a busy port making it the largest city on the West Coast at the time; between 1870 and 1900, approximately one quarter of California's population resided in the city proper.[28] In 1856, San Francisco became a consolidated city-county.[29] After three-quarters of the city was destroyed by the 1906 earthquake and fire,[30] it was quickly rebuilt, hosting the Panama-Pacific International Exposition nine years later. In World War II, it was a major port of embarkation for service members shipping out to the Pacific Theater.[31] It then became the birthplace of the United Nations in 1945.[32][33][34] After the war, the confluence of returning servicemen, significant immigration, liberalizing attitudes, the rise of the "beatnik" and "hippie" countercultures, the Sexual Revolution, the Peace Movement growing from opposition to United States involvement in the Vietnam War, and other factors led to the Summer of Love and the gay rights movement, cementing San Francisco as a center of liberal activism in the United States. Politically, the city votes strongly along liberal Democratic Party lines.[35]

A popular tourist destination,[36] San Francisco is known for its cool summers, fog, steep rolling hills, eclectic mix of architecture, and landmarks, including the Golden Gate Bridge, cable cars, the former Alcatraz Federal Penitentiary, Fisherman's Wharf, and its Chinatown district. San Francisco is also the headquarters of companies such as Wells Fargo, Twitter, Block, Airbnb, Levi Strauss & Co., Gap Inc., Salesforce, Dropbox, Pacific Gas and Electric Company, Uber, Lyft and Cruise. The city, and the surrounding Bay Area, is a global center of the sciences and arts[37][38] and is home to a number of educational and cultural institutions, such as the University of California, San Francisco (UCSF), the University of San Francisco (USF), San Francisco State University (SFSU), the de Young Museum, the San Francisco Museum of Modern Art, the SFJAZZ Center, the San Francisco Symphony and the California Academy of Sciences. More recently, statewide droughts in California have strained the city's water security.[39][40]
