Sure, L.A. may be home to Hollywood glitz, excess and triviality, but it’s also the No. 1 region of the state when it comes to charitable giving.

That’s the conclusion of a study by the NewTithing Group, which studied charitable contributions of Californians earning at least $200,000 annually, as measured by the median share of liquid assets.

It found those residing in Los Angeles donated nearly $5,000 annually in 2004, or roughly 1 percent of their $500,000 in assets. By contrast, rich Californians living in the Bay Area, Central Coast and other regions gave less than 1 percent of their investment asset wealth. The median affluent resident in the state donated 0.69 percent of their wealth, or about $3,900.

The study by the San Francisco philanthropic research organization was based on data from the California Franchise Tax board and did not provide a reason for the disparity. But in an interview with the Los Angeles Times the organization’s director, Tim Stone, suggested that demographics could be at play, with L.A.’s older, wealthier residents more apt to part with their money that the younger, wealthy residents of the Bay area.
