Fourth-worst community for car thefts: San Francisco/Oakland/Hayward, Calif.
You can leave your heart in San Francisco, just don't leave your keys in your car there.

That's because the Bay Area saw 29,326 car thefts in 2013, or 649.34 for every 100,000 residents.

Scafidi says that while San Francisco proper has a strong economy that usually translates into lower crime, other parts of the metro area aren't so lucky.

"You have to remember that the San Francisco metro area isn't just San Francisco, it's also places like Hayward and Oakland," he says. "And Oakland isn't exactly known as a quiet bedroom community."

Located across the San Francisco Bay from San Francisco proper, Oakland ranks No. 9 in NeighborhoodScout's list of America's most dangerous cities.
