Atlas of Giving: U.S. Charitable Giving Tops $450 Billion in 2014

"Charitable giving in the U.S. is primarily a function of specific economic and demographic factors, coupled with the impact of regional, national and world events," Rob Mitchell, CEO of the Atlas of Giving, said. "How a charity chooses to go about raising money and who they raise it from determines what impact the various drivers of giving activity have on gifts to that organization."
