Wealthiest Donors Gave 9 Percent of Their Income in 2007, Study Finds

Households earning between $200,000 and $5-million gave more, on average, to nonprofit groups in 2007 than they did two years earlier, but those making at least $5-million gave less.

Because the very richest people account for such a significant portion of total giving by the wealthy, donating an average of $855,200, that meant that overall giving from affluent households in the study dropped by 9.7 percent.
