The Almanac of American Philanthropy is a reference book published by the nonprofit Philanthropy Roundtable in 2016 to capture the history, purpose, effects, and modern direction of private philanthropy in the United States. Philanthropy in the U.S. is a major part of the economy with $360 billion given every year and 8 billion hours of time volunteered. Philanthropy is a major cultural force in the U.S., handling many social responsibilities, thanks to individual giving levels that are two to twenty times higher than in other comparable nations.
