President Obama and his wife, Michelle, donated $329,000 to 40 charities in 2009, according to the White House blog.
The Obamas' tax returns were made public April 15, a White House tradition. They showed a focus on health and education charities, such as the National Coalition for Homeless Veterans, the Illinois Reading Council and the National Multiple Sclerosis Society.
Their typical donation was $5,000 or $10,000. The largest gifts, $50,000, went to the United Negro College Fund and CARE, a humanitarian organization fighting global poverty.
The contributions amounted to 6 percent of the $5.5 million adjusted gross income reported by the Obamas, who filed a joint return. The vast majority of their income came from the sale of the president's books.
In addition, Obama donated his $1.4 million Nobel Peace Prize to 10 charities. For the record, that did not count as income, nor as a charitable deduction, the website said.
Meanwhile, Vice President Joe Biden and his wife, Jill, gave $4,820 in cash and goods in 2009, or 1.5 percent of their adjusted gross income of $333,100, according to the White House.
So how does that compare with President George W. Bush? The Chronicle of Philanthropy has reported that George and Laura Bush donated $165,600 to churches and charitable organizations in 2007, the last year that such information is available.
That amounted to nearly 18 percent of their adjusted gross income of $936,000, according to the Chronicle.
