The San Francisco Bay Area Portal![]() ![]() The San Francisco Bay Area (referred to locally as the Bay Area) is a populous region surrounding the San Francisco and San Pablo estuaries in Northern California. The region encompasses the major cities and metropolitan areas of San Jose, San Francisco, and Oakland, along with smaller urban and rural areas. The Bay Area's nine counties are Alameda, Contra Costa, Marin, Napa, San Francisco, San Mateo, Santa Clara, Solano, and Sonoma. Home to approximately 7.68 million people, the nine-county Bay Area contains many cities, towns, airports, and associated regional, state, and national parks, connected by a network of roads, highways, railroads, bridges, tunnels, and commuter rail. The combined statistical area of the region is the second-largest in California (after the Greater Los Angeles area), the fifth-largest in the United States, and the 43rd-largest urban area in the world with 8.80 million people. The Bay Area has the second-most Fortune 500 companies in the United States, after the New York metropolitan area, and is known for its natural beauty, liberal politics, entrepreneurship, and diversity. The area ranks second in highest density of college graduates, after the Washington, D.C. metropolitan area and performs above the state median household income in the 2010 census; it includes the five highest California counties by per capita income and two of the top 25 wealthiest counties in the United States. Based on a 2013 population report from the California Department of Finance, the Bay Area is the only region in California where the rate of people migrating in from other areas in the United States is greater than the rate of those leaving the region, led by Alameda and Contra Costa counties.

The main prison building was built in 1910-12 during the time it was a United States Army military prison; Alcatraz was the site of a citadel from the 1860s. The United States Disciplinary Barracks on Alcatraz was acquired by the United States Department of Justice on October 12, 1933, and the island became a Federal Bureau of Prisons federal prison in August 1934, after the buildings were modernized to meet the requirements of a top-notch security prison. Given this high security and the location of Alcatraz in the cold waters and strong currents of San Francisco Bay, at least a mile off the coast, the prison operators believed Alcatraz to be inescapable and America's strongest prison.
