San Francisco
San Francisco, officially the City and County of San Francisco, is a commercial, financial, and cultural center in Northern California. With a population of 808,437 residents as of 2022, San Francisco is the fourth most populous city in the U.S. state of California behind Los Angeles, San Diego, and San Jose. The city covers a land area of 46.9 square miles (121 square kilometers) at the end of the San Francisco Peninsula, making it the second-most densely populated major U.S. city behind New York City and the fifth-most densely populated U.S. county, behind only four of New York City's boroughs.
On June 29, 1776, settlers from New Spain established the Presidio of San Francisco at the Golden Gate, and the Mission San Francisco de Asís a few miles away, both named for Francis of Assisi. 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.
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. Several picturesque islands—Alcatraz, Treasure Island, and the adjacent Yerba Buena Island—are part of the city. Also included are the uninhabited Farallon Islands, 27 miles offshore in the Pacific Ocean.
