According to Wikipedia:

San Francisco is the fourth most populous city in California and the 12th most populous city in the United States, with a 2008 estimated population of 808,976.[8] It is the second most densely populated major city in the U.S.[10] and is the financial, cultural, and transportation center of the larger San Francisco Bay Area, a region of more than seven million people.[11][12] The city is located at the northern end of the San Francisco Peninsula, with the Pacific Ocean to the west and San Francisco Bay to the north and east, and Daly City and Brisbane to the south.

Again, according to Wikipedia:

Oakland (pronounced /ˈoʊklənd/) is the eighth-largest city in the U.S. state of California[2] and a major West Coast port city, located on the bay about eight miles east of San Francisco. Oakland is a major hub city for the Bay Area subregion collectively called the East Bay, and it is the county seat of Alameda County. Based on United States Census Bureau estimates for 2008, Oakland is the 44th-largest city in the United States with a population of 420,183.[3]
