Foundations support everything from A to Z — from the arts to zoos. They give away money in the form of grants or provide free services. Governments generally do not tax these organizations.
    Wealthy individuals establish most foundations, But companies and communities can also form them.
    In the United States, the Foundation Center estimates that foundations gave away almost 34,000 million dollars last year. The Giving U. S. A. Foundation says that was about 12 percent of all charitable giving by Americans.
    Foundations are required to provide the federal tax agency with information on their financial activities. There are groups, like the Foundation Center in New York, that also keep records on foundations. The center, in its most recent report, says the nation had almost 68,000 grant-making foundations in 2004.
    That year, about 1, 300 new foundations were formed.[34]The increase was small compared to the year 2000, when more than 6, 000 new foundations appeared.
    The Foundation Center divides private foundations into three groups. Independent foundations are set up by individuals or families. The Bill and Melinda GatesFoundation is an example. There are more than 60, 000 independent foundations in the United States, far more than any other kind. Corporate foundations receive money from the companies that created them, but are legally separate. The third kind, operating foundations, use their money to provide programs and services. So they generally do not give away grants.
    There also are public foundations, or "grant-making public charities". The New York Community Trust is the largest example. Public foundations depend on money from large numbers of individuals and groups. They may also invest in stocks and earn money from selling gifts of property.
