Alameda County is home to over 1.5 million people living in 14 incorporated cities as well as in six unincorporated communities and rural areas throughout the 813 square miles of the County.
The city is also home to many high-technology companies, earning it the nickname “Silicon Island.” Alameda was among the first communities in California to choose the council-manager form of government, which was adopted later by most California cities. The College of Alameda opened in 1970.
