World's most big-hearted nation: the United States.



The United States is the world's most generous nation, according to a global index of giving, as a higher proportion of Americans helped a stranger than any other country in the world.

The 2013 World Giving Index – published annually by international nonprofit organization Charities Aid Foundation – looks at three measures: monetary giving, volunteering and helping of strangers in a typical month. The survey, published on Tuesday, was carried out in 2012 across 135 countries.
