10. San Francisco

Per-capita GDP: $58,783

San Francisco isn’t just where Tony Bennett left his heart. It’s the cultural center of Northern California’s Bay Area and a favorite destination of tourists from all over the world. A Sept. 3, 2010, article in the San Francisco Chronicle described the tourism industry as the city’s largest private-sector employer and estimated its worth at $7.8 billion per year.

Since the 1990s, San Francisco’s economy also has been positively affected by its proximity to Silicon Valley. During the late 2000s, the city attracted thousands of technology industry professionals. The year-round mild climate couldn’t hurt either.
