San Francisco, officially the City and County of San Francisco, is the financial, cultural, and transportation center of the San Francisco Bay Area, a region of more than 7.4 million people which includes San Jose and Oakland. The only consolidated city-county in California, it encompasses a land area of Template:Convert on the northern end of the San Francisco Peninsula, giving it a density of 17,243 people per square mile (6,655/km2). It is the most densely settled large city (population greater than 200,000) in the state of California and the second-most densely populated large city in the United States. San Francisco is the fourth most populous city in California and the 13th most populous city in the United States, with a 2010 estimated population of 805,235.
In 1776, Spanish colonials established a fort at the Golden Gate and a mission named for Francis of Assisi on the site. The California Gold Rush in 1848 propelled the city into a period of rapid growth, increasing the population in one year from 1,000 to 25,000, and thus transforming it into the largest city on the West Coast at the time. After three-quarters of the city was destroyed by the 1906 earthquake and fire, San Francisco was quickly rebuilt, hosting the Panama-Pacific International Exposition nine years later. During World War II, San Francisco was the port of embarkation for service members shipping out to the Pacific Theater. After the war, the confluence of returning servicemen, massive immigration, liberalizing attitudes, 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.
Today, San Francisco is a popular international tourist destination, renowned for its chilly summer fog, steep rolling hills, eclectic mix of Victorian and modern architecture, and its famous landmarks, including the Golden Gate Bridge, cable cars, and Chinatown. The city is also a principal banking and finance center, and the home to more than 30 international financial institutions, helping to make San Francisco rank eighteenth in the world's top producing cities, ninth in the United States, and thirteenth place in the top twenty global financial centers.
- Main article: History of San Francisco
Upon independence from Spain in 1821, the area became part of Mexico. Under Mexican rule, the mission system gradually ended and its lands began to be privatized. In 1835, Englishman William Richardson erected the first independent homestead, near a boat anchorage around what is today Portsmouth Square. Together with Alcalde Francisco de Haro, he laid out a street plan for the expanded settlement, and the town, named Yerba Buena, began to attract American settlers. Commodore John D. Sloat claimed California for the United States on July 7, 1846, during the Mexican-American War, and Captain John B. Montgomery arrived to claim Yerba Buena two days later. Yerba Buena was renamed San Francisco on January 30 of the next year, and Mexico officially ceded the territory to the United States at the end of the war. Despite its attractive location as a port and naval base, San Francisco was still a small settlement with inhospitable geography.The California Gold Rush brought a flood of treasure seekers. With their sourdough bread in tow, prospectors accumulated in San Francisco over rival Benicia, raising the population from 1,000 in 1848 to 25,000 by December 1849. The promise of fabulous riches was so strong that crews on arriving vessels deserted and rushed off to the gold fields, leaving behind a forest of masts in San Francisco harbor. California was quickly granted statehood, and the U.S. military built Fort Point at the Golden Gate and a fort on Alcatraz Island to secure the San Francisco Bay. Silver discoveries, including the Comstock Lode in 1859, further drove rapid population growth. With hordes of fortune seekers streaming through the city, lawlessness was common, and the Barbary Coast section of town gained notoriety as a haven for criminals, prostitution, and gambling.
Entrepreneurs sought to capitalize on the wealth generated by the Gold Rush. Early winners were the banking industry which saw the founding of Wells Fargo in 1852 and the Bank of California in 1864. Development of the Port of San Francisco and the establishment in 1869 of overland access to the Eastern U.S. rail system via the newly completed Pacific Railroad (the construction of which the city had only reluctantly helped support) helped make the Bay Area a center for trade. Catering to the needs and tastes of the growing population, Levi Strauss opened a dry goods business and Domingo Ghirardelli began manufacturing chocolate. Immigrant laborers made the city a polyglot culture, with Chinese railroad workers creating the city's Chinatown quarter. The first cable cars carried San Franciscans up Clay Street in 1873. The city's sea of Victorian houses began to take shape, and civic leaders campaigned for a spacious public park, resulting in plans for Golden Gate Park. San Franciscans built schools, churches, theaters, and all the hallmarks of civic life. The Presidio developed into the most important American military installation on the Pacific coast. By the turn of the century, San Francisco was a major city known for its flamboyant style, stately hotels, ostentatious mansions on Nob Hill, and a thriving arts scene.
At 5:12 am on April 18, 1906, a major earthquake struck San Francisco and northern California. As buildings collapsed from the shaking, ruptured gas lines ignited fires that would spread across the city and burn out of control for several days. With water mains out of service, the Presidio Artillery Corps attempted to contain the inferno by dynamiting blocks of buildings to create firebreaks. More than three-quarters of the city lay in ruins, including almost all of the downtown core. Contemporary accounts reported that 498 people lost their lives, though modern estimates put the number in the several thousands. More than half the city's population of 400,000 were left homeless. Refugees settled temporarily in makeshift tent villages in Golden Gate Park, the Presidio, on the beaches, and elsewhere. Many fled permanently to the East Bay.
Rebuilding was rapid and performed on a grand scale. Rejecting calls to completely remake the street grid, San Franciscans opted for speed. Amadeo Giannini's Bank of Italy, later to become Bank of America, provided loans for many of those whose livelihoods had been devastated. The destroyed mansions of Nob Hill became grand hotels. City Hall rose again in splendorous Beaux Arts style, and the city celebrated its rebirth at the Panama-Pacific International Exposition in 1915.
In ensuing years, the city solidified its standing as a financial capital; in the wake of the 1929 stock market crash, not a single San Francisco-based bank failed. Indeed, it was at the height of the Great Depression that San Francisco undertook two great civil engineering projects, simultaneously constructing the San Francisco – Oakland Bay Bridge and the Golden Gate Bridge, completing them in 1936 and 1937 respectively. It was in this period that the island of Alcatraz, a former military stockade, began its service as a federal maximum security prison, housing notorious inmates such as Al Capone, and Robert Franklin Stroud, The Birdman of Alcatraz. San Francisco later celebrated its regained grandeur with a World's Fair, the Golden Gate International Exposition in 1939–40, creating Treasure Island in the middle of the bay to house it.
During World War II, the Hunters Point Naval Shipyard became a hub of activity, and Fort Mason became the primary port of embarkation for service members shipping out to the Pacific Theater of Operations. The explosion of jobs drew many people, especially African Americans from the South, to the area. After the end of the war, many military personnel returning from service abroad and civilians who had originally come to work decided to stay. The UN Charter creating the UN was drafted and signed in San Francisco in 1945 and, in 1951, the Treaty of San Francisco officially ended the war with Japan.
Urban planning projects in the 1950s and 1960s involved widespread destruction and redevelopment of west side neighborhoods and the construction of new freeways, of which only a series of short segments were built before being halted by citizen-led opposition. The Transamerica Pyramid was completed in 1972, and in the 1980s the Manhattanization of San Francisco saw extensive high-rise development downtown. Port activity moved to Oakland, the city began to lose industrial jobs, and San Francisco began to turn 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. Over this period, San Francisco became a magnet for America's counterculture. Beat Generation writers fueled the San Francisco Renaissance and centered on the North Beach neighborhood in the 1950s. Hippies flocked to Haight-Ashbury in the 1960s, reaching a peak with the 1967 Summer of Love. In the 1970s, the city became a center of the gay rights movement, with the emergence of The Castro as an urban gay village, the election of Harvey Milk to the Board of Supervisors, and his assassination, along with that of Mayor George Moscone, in 1978.
The 1989 Loma Prieta earthquake caused destruction and loss of life throughout the Bay Area. In San Francisco, the quake severely damaged structures in the Marina and South of Market districts and precipitated the demolition of the damaged Embarcadero Freeway and much of the damaged Central Freeway, allowing the city to reclaim its historic downtown waterfront.
During the dot-com boom of the late 1990s, startup companies invigorated the economy. Large numbers of entrepreneurs and computer application developers moved into the city, followed by marketing and sales professionals, changing the social landscape as once-poorer neighborhoods became gentrified. When the bubble burst in 2001, many of these companies folded, and their employees left, although high technology and entrepreneurship continue to be mainstays of the San Francisco economy.
San Francisco is located on the West Coast of the United States at the tip of the San Francisco Peninsula and includes significant stretches of the Pacific Ocean and San Francisco Bay within its boundaries. Several islands—Alcatraz, Treasure Island, and the adjacent Yerba Buena Island, and a small portion of Alameda Island, Red Rock Island, and Angel Island are part of the city. Also included are the uninhabited Farallon Islands, Template:Convert offshore in the Pacific Ocean. The mainland within the city limits roughly forms a "seven-by-seven-mile square," a common local colloquialism referring to the city's shape, though its total area, including water, is nearly Template:Convert.
San Francisco is famous for its hills. There are more than 50 hills within city limits. Some neighborhoods are named after the hill on which they are situated, including Nob Hill, Pacific Heights, and Russian Hill. Near the geographic center of the city, southwest of the downtown area, are a series of less densely populated hills. Twin Peaks, a pair of hills resting at one of the city's highest points, forms a popular overlook spot. San Francisco's tallest hill, Mount Davidson, is Template:Convert high and is capped with a Template:Convert tall cross built in 1934. Dominating this area is Sutro Tower, a large red and white radio and television transmission tower.
The nearby San Andreas and Hayward Faults are responsible for much earthquake activity, although neither physically passes through the city itself. The San Andreas Fault caused the earthquakes in 1906 and 1989. Minor earthquakes occur on a regular basis. The threat of major earthquakes plays a large role in the city's infrastructure development. The city has repeatedly upgraded its building codes, requiring retrofits for older buildings and higher engineering standards for new construction. However, there are still thousands of smaller buildings that remain vulnerable to quake damage.
San Francisco's shoreline has grown beyond its natural limits. Entire neighborhoods such as the Marina and Hunters Point, as well as large sections of the Embarcadero, sit on areas of landfill. Treasure Island was constructed from material dredged from the bay as well as material resulting from tunneling through Yerba Buena Island during the construction of the Bay Bridge. Such land tends to be unstable during earthquakes; the resultant liquefaction causes extensive damage to property built upon it, as was evidenced in the Marina district during the 1989 Loma Prieta earthquake.
A popular quote incorrectly attributed to Mark Twain is "The coldest winter I ever spent was a summer in San Francisco." San Francisco's climate is characteristic of the cool-summer Mediterranean climate of California’s coast, "generally characterized by moist mild winters and dry summers." Since it is surrounded on three sides by water, San Francisco's weather is strongly influenced by the cool currents of the Pacific Ocean, which moderates temperature swings and produces a remarkably mild year-round climate with little seasonal temperature variation.
Among major U.S. cities, San Francisco has the coldest daily mean, maximum, and minimum temperatures for June, July and August. During the summer, rising hot air in California's interior valleys creates a low pressure area that draws winds from the North Pacific High through the Golden Gate, which creates the city's characteristic cool winds and fog. The fog is less pronounced in eastern neighborhoods and during the late summer and early fall, which is the warmest time of the year.
Because of its sharp topography and maritime influences, San Francisco exhibits a multitude of distinct microclimates. The high hills in the geographic center of the city are responsible for a 20% variance in annual rainfall between different parts of the city. They also protect neighborhoods directly to their east from the foggy and sometimes very cold and windy conditions experienced in the Sunset District; for those who live on the eastern side of the city, San Francisco is sunnier, with an average of 260 clear days, and only 105 cloudy days per year.
Temperatures exceed Template:Convert on average only 28 days a year. The dry period of May to October is mild to warm, with average high temperatures of Template:Convert and lows of Template:Convert. The rainy period of November to April is slightly cooler with high temperatures of Template:Convert and lows of Template:Convert. On average, there are 67 rainy days a year, and annual precipitation averages Template:Convert. Snow is extraordinarily rare, with only 10 instances recorded since 1852, most recently in 1976.
The highest recorded temperature at the official National Weather Service office was Template:Convert on July 17, 1988, and June 14, 2000. The lowest recorded temperature was Template:Convert on December 11, 1932.
- Main article: Neighborhoods in San Francisco
Template:See also The historic center of San Francisco is the northeast quadrant of the city bordered by Market Street to the south. It is here that the Financial District is centered, with Union Square, the principal shopping and hotel district, nearby. Cable cars carry riders up steep inclines to the summit of Nob Hill, once the home of the city's business tycoons, and down to Fisherman's Wharf, a tourist area featuring Dungeness crab from a still-active fishing industry. Also in this quadrant are Russian Hill, a residential neighborhood with the famously crooked Lombard Street, North Beach, the city's Little Italy, and Telegraph Hill, which features Coit Tower. Nearby is San Francisco's Chinatown, established in the 1840s.
The Mission District was populated in the 19th century by Californios and working-class immigrants from Germany, Ireland, Italy and Scandinavia. In the 1910s, a wave of Central American immigrants settled in the Mission and, in the 1950s, immigrants from Mexico began to predominate. In recent years rapid gentrification has spread, primarily along the Valencia Street corridor, which is strongly associated with modern hipster sub-culture. Haight-Ashbury, famously associated with 1960s hippie culture, later became home to expensive boutiques and a few controversial chain stores, although it still retains some bohemian character. Historically known as Eureka Valley, the area now popularly called the Castro is the center of gay life in the city.
The city's Japantown district suffered when its Japanese American residents were forcibly removed and interned during World War II. The nearby Western Addition became established with a large African American population at the same time. The "Painted Ladies", a row of well-restored Victorian homes, stand alongside Alamo Square, and the mansions built by the San Francisco business elite in the wake of the 1906 earthquake can be found in Pacific Heights. The Marina to the north is a lively area with many young urban professionals.
The Richmond, the vast region north of Golden Gate Park that extends to the Pacific Ocean, has a portion called "New Chinatown" but is also home to immigrants from other parts of Asia and Russia. South of Golden Gate Park lies the Sunset with a predominantly Asian population. The Richmond and the Sunset are largely middle class and, together, are known as The Avenues. These two districts are each sometimes further divided into two regions: the Outer Richmond and Outer Sunset can refer to the more Western portions of their respective district and the Inner Richmond and Inner Sunset can refer to the more Eastern portions. Bayview-Hunters Point in the southeast section of the city is one of the poorest neighborhoods and suffers from a high rate of crime, though the area has been the focus of controversial plans for urban renewal.
The South of Market, once filled with decaying remnants of San Francisco's industrial past, has seen significant redevelopment. The locus of the dot-com boom during the late 1990s, by 2004 South of Market began to see skyscrapers and condominiums dot the area (see Manhattanization). Following the success of nearby South Beach, another neighborhood, Mission Bay, underwent redevelopment, anchored by a second campus of the University of California, San Francisco. Just southwest of Mission Bay is the Potrero Hill neighborhood featuring sweeping views of downtown San Francisco.
Beaches and parksEdit
Several of San Francisco's parks and nearly all of its beaches form part of the regional Golden Gate National Recreation Area, one of the most visited units of the National Park system in the United States with over 13 million visitors a year. Among the GGNRA's attractions within the city are Ocean Beach, which runs along the Pacific Ocean shoreline and is frequented by a vibrant surfing community, and Baker Beach, which is located in a cove west of the Golden Gate and part of the Presidio, a former military base. Also within the Presidio is Crissy Field, a former airfield that was restored to its natural salt marsh ecosystem. The GGNRA also administers Fort Funston, Lands End, Fort Mason, and Alcatraz. The National Park Service separately administers the San Francisco Maritime National Historical Park – a fleet of historic ships and waterfront property around Aquatic Park.
There are more than 200 parks maintained by the San Francisco Recreation and Parks Department. The largest and best-known city park is Golden Gate Park, which stretches from the center of the city west to the Pacific Ocean. Once covered in native grasses and sand dunes, the park was conceived in the 1860s and was created by the extensive planting of thousands of non-native trees and plants. The large park is rich with cultural and natural attractions such as the Conservatory of Flowers, Japanese Tea Garden and San Francisco Botanical Garden. Lake Merced is a fresh-water lake surrounded by parkland and near the San Francisco Zoo, a city-owned park that houses more than 250 animal species, many of which are designated as endangered. The only park managed by the California State Park system located principally in San Francisco, Candlestick Point was the state's first urban recreation area.
Culture and contemporary lifeEdit
- Main article: Culture of San Francisco
Template:See also In recent years, the wealth resulting from the IT boom from the nearby Silicon Valley, as well as from the recent Dot-Com booms has created a high standard of living in San Francisco, attracting white-collar workers to San Francisco from all over the world. Many neighborhoods that were once blue-collar, middle, and lower class have been gentrifying, as many of the city's traditional business and industrial districts have experienced a renaissance driven by the redevelopment of the Embarcadero, including the neighborhoods South Beach and Mission Bay. The city's property values and household income have risen to among the highest in the nation, creating a large, and upscale restaurant, retail, and entertainment scene. According to a 2008 quality of life survey of global cities, San Francisco has the second highest quality of living of any U.S. city. Due to the exceptionally high cost of living, many of the city's middle and lower class families have been leaving the city for the outer suburbs of the Bay Area, or for California's Central Valley.
Although the centralized commerce and shopping districts of the Financial District and the area around Union Square are well-known around the world, San Francisco is also characterized by its culturally rich streetscapes featuring mixed-use neighborhoods anchored around central commercial corridors to which residents and visitors alike can walk. Because of these characteristics, San Francisco was rated "most walkable" city by the website Walkscore.com. Many neighborhoods feature a mix of businesses, restaurants and venues that cater to both the daily needs of local residents while also serving many visitors and tourists. Some neighborhoods are dotted with boutiques, cafes and nightlife such as Union Street in Cow Hollow, and 24th Street in Noe Valley. Others are less so, such as Irving Street in the Sunset, or Mission Street in the Mission. This approach especially has influenced the continuing South of Market neighborhood redevelopment with businesses and neighborhood services rising alongside high-rise residences.
The international character San Francisco has fostered since its founding is continued today by large numbers of immigrants from Asia and Latin America. With 39% of its residents born overseas, San Francisco has numerous neighborhoods filled with businesses and civic institutions catering to new arrivals. In particular, the arrival of many ethnic Chinese, which accelerated beginning in the 1970s, has complemented the long-established community historically based in Chinatown throughout the city and has transformed the annual Chinese New Year Parade into the largest event of its kind outside China.
Following the arrival of the "beat" writers and artists of the 1950s, to the societal changes that culminated with the Summer of Love in the Haight-Ashbury district during the 1960s, San Francisco became an epicenter of liberal activism, with Democrats and Greens dominating city politics. San Francisco has not voted more than 20% for a Republican presidential or senatorial candidate since 1988. In 2006, the Board of Supervisors passed the Healthy San Francisco program, which subsidizes medical care for certain uninsured residents. Healthy San Francisco covers most medical services excluding dental and vision, but only pays providers within San Francisco.
The city's large gay population has created and sustained a politically and culturally active community over many decades, developing a powerful presence in San Francisco's civic life. One of the most popular destinations for gay tourists internationally, the city hosts San Francisco Pride, one of the largest and oldest pride parades.
Entertainment and performing artsEdit
San Francisco's War Memorial and Performing Arts Center hosts some of the most enduring performing-arts companies in the U.S. The War Memorial Opera House houses the San Francisco Opera, the second-largest opera company in North America as well as the San Francisco Ballet, while the San Francisco Symphony plays in Davies Symphony Hall. The Herbst Theatre stages an eclectic mix of music performances, as well as public radio's City Arts & Lectures.
The Fillmore is a music venue located in the Western Addition. It is the second incarnation of the historic venue that gained fame in the 1960s under concert promoter Bill Graham, housing the stage where now-famous musicians such as the Grateful Dead, Janis Joplin and Jefferson Airplane first performed, fostering the San Francisco Sound. Beach Blanket Babylon is a zany musical revue and a civic institution that has performed to sold-out crowds in North Beach since 1974.
The American Conservatory Theater (A.C.T.) has been a force in Bay Area performing arts since its arrival in San Francisco in 1967, regularly staging productions. San Francisco frequently hosts national touring productions of Broadway theatre shows in a number of vintage 1920s-era venues in the Theater District including the Curran, Orpheum, and Golden Gate Theatres.
- Main article: List of museums in San Francisco
The Museum of Modern Art (SFMOMA) houses 20th century and contemporary works of art. It moved to its current building in the South of Market neighborhood in 1995 and now attracts more than 600,000 visitors annually. The Palace of the Legion of Honor holds primarily European antiquities and works of art at its Lincoln Park building modeled after its Parisian namesake. It is administered by Fine Arts Museums of San Francisco, which also operates the de Young Museum in Golden Gate Park. The de Young's collection features American decorative pieces and anthropological holdings from Africa, Oceania and the Americas. Prior to construction of its current copper-clad structure, completed in 2005, the de Young also housed the Asian Art Museum, which, with artifacts from over 6,000 years of history across Asia, moved into the former public library next to Civic Center in 2003.
Opposite the Music Concourse from the de Young stands the California Academy of Sciences, a natural history museum that also hosts the Morrison Planetarium and Steinhart Aquarium. Its current structure, featuring a living roof, is an example of sustainable architecture and opened in 2008. The Palace of Fine Arts, built originally for the 1915 Panama-Pacific Exposition, has since 1969 housed the Exploratorium, an interactive science museum.
- Main article: Media in San Francisco
The major daily newspaper in San Francisco is the San Francisco Chronicle, which is currently Northern California's most widely circulated newspaper. The Chronicle is most famous for a former columnist, the late Herb Caen, whose daily musings attracted critical acclaim and represented the "voice of San Francisco". The San Francisco Examiner, once the cornerstone of William Randolph Hearst's media empire and the home of Ambrose Bierce, declined in circulation over the years and now takes the form of a free daily tabloid. Sing Tao Daily claims to be the largest of several Chinese language dailies that serve the Bay Area. Alternative weekly newspapers include the San Francisco Bay Guardian and SF Weekly. San Francisco Magazine and 7x7 are major glossy magazines about San Francisco. The national newsmagazine Mother Jones is also based in San Francisco.
The San Francisco Bay Area is the sixth-largest TV market and the fourth-largest radio market in the U.S. The city's oldest radio station, KCBS (AM), began as an experimental station in San Jose in 1909. KALW was the city's first FM radio station when it signed on the air in 1941. All major U.S. television networks have affiliates serving the region, with most of them based in the city. There also are several unaffiliated stations, and BBC, CNN and ESPN have regional news bureaus in San Francisco. The city's first television station was KPIX, which began broadcasting in 1948.
Public broadcasting outlets include both a television station and a radio station, both broadcasting under the call letters KQED from a facility near the Potrero Hill neighborhood. KQED-FM is the most-listened-to National Public Radio affiliate in the country. San Francisco–based CNET and Salon.com pioneered the use of the Internet as a media outlet.
- Main article: Sports in San Francisco
The San Francisco 49ers of the National Football League (NFL) are the longest-tenured major professional sports franchise in the city. The team began play in 1946 as an All-America Football Conference (AAFC) league charter member, moved to the NFL in 1950 and into Candlestick Park in 1971. The 49ers won five Super Bowl titles in the 1980s and 1990s behind coaches Bill Walsh and George Seifert, and stars such as Joe Montana, Steve Young, Ronnie Lott, and Jerry Rice.
Major League Baseball's San Francisco Giants left New York for California prior to the 1958 season. Though boasting such stars as Willie Mays, Willie McCovey and Barry Bonds, the club went 52 years until its first World Series title in 2010. The Oakland Athletics had swept the Giants in the 1989 World Series, after Game 3 in San Francisco was infamously pre-empted by the Loma Prieta earthquake. The Giants play at AT&T Park, which opened in 2000, a cornerstone project of the South Beach and Mission Bay redevelopment.
At the collegiate level, the Dons of the University of San Francisco compete in NCAA Division I, where Bill Russell guided the program to basketball championships in 1955 and 1956. The San Francisco State Gators and the Academy of Art University Urban Knights compete in Division II. AT&T Park has since 2002 hosted an annual post-season college football bowl game, currently named the Kraft Fight Hunger Bowl.
The Bay to Breakers footrace, held annually since 1912, is best known for colorful costumes and a celebratory community spirit. The San Francisco Marathon attracts more than 21,000 participants. The Escape from Alcatraz triathlon has, since 1980, attracted 2,000 top professional and amateur triathletes for its annual race. The Olympic Club, founded in 1860, is the oldest athletic club in the United States. Its private golf course, situated on the border with Daly City, has hosted the U.S. Open on four occasions, and will host it a fifth time in 2012. The public Harding Park Golf Course is an occasional stop on the PGA Tour. San Francisco will host the 2013 America's Cup yacht racing competition.
With an ideal climate for outdoor activities, San Francisco has ample resources and opportunities for amateur and participatory sports and recreation. There are more than Template:Convert of bicycle paths, lanes and bike routes in the city, and the Embarcadero and Marina Green are favored sites for skateboarding. Extensive public tennis facilities are available in Golden Gate Park and Dolores Park, as well as at smaller neighborhood courts throughout the city. Boating, sailing, windsurfing and kitesurfing are among the popular activities on San Francisco Bay, and the city maintains a yacht harbor in the Marina District. San Francisco residents have often ranked among the fittest in the U.S. Template:-
Template:See also Tourism is the backbone of the San Francisco economy. Its frequent portrayal in music, film, and popular culture has made the city and its landmarks recognizable worldwide. It is the city where Tony Bennett "left his heart," where the Birdman of Alcatraz spent many of his final years, and where Rice-a-Roni was said to be the favorite treat. San Francisco attracts the third-highest number of foreign tourists of any city in the U.S.Template:Update after and claims Pier 39 near Fisherman's Wharf as the third-most popular tourist attraction in the nation. More than 16 million visitors arrived in San Francisco in 2007, injecting nearly $8.2 billion into the economy—both all-time high figures for the city. With a large hotel infrastructure and a world-class convention facility in the Moscone Center, San Francisco is also among the top-ten North American destinations for conventions and conferences.The legacy of the California Gold Rush turned San Francisco into the principal banking and finance center of the West Coast in the early twentieth century. Montgomery Street in the Financial District became known as the "Wall Street of the West," home to the Federal Reserve Bank of San Francisco, the Wells Fargo corporate headquarters, and the site of the now-defunct Pacific Coast Stock Exchange. Bank of America, a pioneer in making banking services accessible to the middle class, was founded in San Francisco and in the 1960s, built the landmark modern skyscraper at 555 California Street for its corporate headquarters. Many large financial institutions, multinational banks and venture capital firms are based in or have regional headquarters in the city. With over 30 international financial institutions, seven Fortune 500 companies, and a large support infrastructure of professional services—including law, public relations, architecture and design—also with significant presence in the city, San Francisco is designated as one of the ten Beta World Cities. The city ranks eighteenth in the world's list of cities by GDP, ninth in the United States, and is fifteenth place in the top twenty Global Financial Centres Index.
San Francisco's economy has increasingly become tied to that of its Bay Area neighbor San Jose and Silicon Valley to its south, sharing the need for highly educated workers with specialized skills. Due to such links with Silicon Valley, San Francisco became an epicenter of the Dot-Com bubble of the 1990s–2000s, and the subsequent Web 2.0 boom of the late 2000s. Many popular and prominent Dot-Com companies and "start-ups" such as Craigslist.org, Twitter, Salesforce.com, and the Wikimedia Foundation among others have established their head offices in San Francisco.
San Francisco has been positioning itself as a biotechnology and biomedical hub and research center. The Mission Bay neighborhood, site of a second campus of UCSF, fosters a budding industry and serves as headquarters of the California Institute for Regenerative Medicine, the public agency funding stem cell research programs statewide. As of 2009, there were 1,800 full-time biochemists and biophysicists employed in San Francisco, with an annual mean wage of $92,620.
Small businesses with fewer than 10 employees and self-employed firms make up 85% of city establishments as lately, it has been particularly popular with entrepreneurs establishing "start-up" companies.
