San Francisco is the fourth most populous city in California and the 12th most populous city in the United States, with a 2008 estimated population of 808,976. The only consolidated city-county in California; it encompasses a land area of 46.7 square miles (121 km2) on the northern end of the San Francisco Peninsula, making it the second most densely populated city in the United States. San Francisco is also the financial, cultural, and transportation center of the larger San Francisco Bay Area, a region of 7.4 million people.
In 1776, the Spanish 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.
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, the cable cars, and Chinatown. The city is also a principal banking and finance center, and the home of over 30 international financial institutions, helping to make San Francisco fifteenth in the world's list of cities by GDP and eighth in the United States.
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.
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.
