Charitable giving by individuals rose to nearly $400 billion in 2016, a record high according to philanthropy research organization Giving USA. Such donations help more than 1.5 million nonprofit organizations that operate in the United States. These groups, which are organized for purposes other than generating profit, are often formed with a public benefit or mutual goal in mind.

Not all nonprofit organizations are alike. Private foundations, like the Bill and Melinda Gates Foundation, usually have a single major source of funding — often large gifts from one family or corporation. The primary activity of these organizations is often to make grants to other charitable organizations.

Public charities, by contrast, frequently rely on funding from many sources, including the general public, governmental agencies, corporations, private foundations, or other public charities. Churches, hospitals, qualified medical research organizations affiliated with hospitals, schools, colleges, and universities are some examples of public charities.
