Fueled by the generosity of individuals, overall relief giving in response to the 2004 Asian tsunami totaled $3.16 billion, a new study says.
One in four American households contributed a combined $2.78 billion, compared to $340 from corporations and $40 million from foundations, says the report by the Center on Philanthropy at Indiana University.
The average gift from individuals was $135, which the report says is almost the same as the average donation following September 11.
More than two in three people gave through their place of worship, while more than one in four gave through their school or work, and more than one in 10 gave through stores.
Wealthier people, those earning between $100,000 and $200,000 a year, gave an average of $164 for tsunami relief, only slightly more than the $104 given by those earning less than $50,000 a year.
Better-educated people gave only slightly more than those with less education, the study says.
