The City and County of San Francisco is the fourth most populous city in California and the 13th most populous city in the United States, with a 2007 estimated population of 799,183. It is the second most densely populated city in the country, and lies within a metropolitan area of 4.2 million people; though, as the financial, cultural, and transportation center of the larger San Francisco Bay Area, it anchors a region of more than 7 million.

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. The city's first television station was KPIX, which began broadcasting on December 24, 1948. Other prominent stations include KGO, KRON, and KTVU.

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, six 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 fifteenth in the world's list of cities by GDP and eighth in the United States.
