The younger wealthy generations are twice as generous with their donations to charity as older generations, according to a new survey.

Generation X, which includes those aged between 28 and 42, gave nearly $20,000 in 2006 to charity, compared to the Baby Boomers (ages 43 to 61) and the Silent Generation (ages 62 to 77) who gave roughly $10,000 each, according to a new survey by Chicago-based wealth manager Northern Trust.
