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.

is a city and the county seat
of Contra Costa County, California
, United States. The population was 35,824 at the 2010 census. The downtown is notable for its large number of preserved old buildings. Martinez is located on the south side of the Carquinez Strait
in the San Francisco Bay Area
, directly facing the city of Benicia
In 1824 the Alhambra Valley was included in the Rancho El Pinole Mexican land grant to Ygnacio Martínez. In 1847, Dr. Robert Semple contracted to provide ferry service from Martinez to Benicia, which for many years was the only crossing on the Carquinez Strait. By 1849, Martínez served as a way station for the California Gold Rush. The town was laid out in 1849 by Col. William M. Smith and named for Martinez. It became the county seat in 1850, but could not incorporate at the time because it lacked the 200 registered voters required, and only became a city in 1876. Martinez was the home of John Muir from 1880 until his death in 1914. He was buried about a mile south of the building that is now the John Muir National Historic Site. Also nearby is the Vicente Martinez Adobe, built in 1849 by the son of Ygnacio Martinez. (more...)

||San Francisco may soon become the first fully gentrified city in America, the urban equivalent of a gated bedroom community ... Now it’s becoming almost impossible for a lot of the people who have made this such a world-class city – people who have been the heart and soul of the city for decades – from the fishers and pasta makers and blue-collar workers to the jazz musicians to the beat poets to the hippies to the punks and so many others –to exist here anymore. And when you’ve lost that part of the city, you’ve lost San Francisco.
