There is some positive economic news for San Francisco officials as tourism numbers were up across the board in 2010.

A study by the San Francisco Travel Association found that San Francisco welcomed 15.92 million visitors last year, an increase of over 3 percent from 2009. Those visitors spent $8.34 billion, which was an increase of over 6 percent from 2009.

The tourism industry also generated $485 million in taxes for the City of San Francisco in 2010.

“This data is good news after the economic challenges of the past few years,” said Joe D’ Alessandro, San Francisco Travel president and CEO. “But we have a long way to go to return to and surpass the levels of years past.”

Among the findings of the survey: the most important factors in visiting San Francisco were the city’s overall ambiance and atmosphere, scenic beauty and San Francisco’s restaurants and cuisine.

Union Square and Fisherman’s Wharf topped the list of most frequently visited neighborhoods.

And the top attractions were Pier 39, the Golden Gate Bridge and Golden Gate Park.
