Marin County is a county located in the North San Francisco Bay Area of the U.S. state of California, across the Golden Gate Bridge from San Francisco. The county seat is San Rafael. Marin County is world-renowned for its stunning natural beauty, liberal politics and affluence. It is the number one county in the nation for per capita income.

The Marin County Civic Center was designed by Frank Lloyd Wright and draws thousands of visitors a year to guided tours of its arch and atrium design (photo here on the left).

Marin County has the second highest median household income in California behind Santa Clara County.

Marin County has the highest per capita income of any county in the United States. This is driven in particular by expensive enclaves in Belvedere, Kentfield, Larkspur, Ross, Tiburon, Mill Valley, Sausalito, San Anselmo and portions of San Rafael and Novato where displays of conspicuous consumption, especially luxury cars, are common. The county has the highest density of BMW cars (locally known as 'Basic Marin Wheels') in the United States, according to dealers in the county.

The traditionally middle class towns of Corte Madera, Fairfax, Novato and San Rafael (where per capita incomes typically paralleled the California state average as late as 1985) also have experienced especially sharp rises in real estate values, due in part to their proximity to the "prestige" address areas. The county's resistance to urban sprawl and its preservation of open space have also had an upward impact on housing prices by reducing the number of new subdivisions built in the area since 1970.
