2010 Commitment To Development Index (PHOTOS)

Sweden is rated as the most overall philanthropic nation on the planet, according to a new report.

Prepared by the Center For Global Development, the 2010 Commitment to Development Index examined how 22 "rich country" governments are contributing to poorer countries. Each year, researchers examine what they call seven "key linkages" the benefactor has with less-developed nations: aid, trade, investment, migration, environment, security, and technology. The scores are then adjusted accordingly in relation to a nation's size, with a score of 5.0 considered average.

With a score of 7.0, Sweden easily topped the 22-nation chart over runners-up Denmark (6.8) and the Netherlands (6.7). The U.S. fared just above average, with a score of 5.4, while Japan (3.3) and South Korea (3.1) were deemed to have the most room for improvement.
