Glenview, Ill. (RNS)—Giving to religious charities and congregations passed the $100 billion mark for the first time in 2007, according to a recent report by the Giving USA Foundation.

Giving to religious groups increased 4.7 percent, bringing the total to $102.32 billion. Overall giving to charitable causes reached $306.39 billion in 2007, a 3.9 percent increase from 2006.

The report, released last month, shows that donations to religious causes accounted for half of all individual charitable giving. Three-quarters of all giving in the U.S. came from individual donations to charity, the report noted.

Del Martin, chair of the Giving USA Foundation, said, “And what you can’t forget is that the ‘little guys,’ the families most affected by the economy, kept on giving despite any worries they might have about their personal situations.”

Charitable giving consistently represents 2.3 percent of the average American’s disposable income each year, a figure that held up in 2007, according to the report.

The survey, conducted by the Center on Philanthropy at Indiana University, analyzed eight charity sub-sectors—arts/culture/humanities; education; environment/animals; health; human services; public-society benefit; international affairs; and religion. Each saw individual increases last year, according to inflation-adjusted estimates.

Meanwhile, presidential campaigns in 2007 raised $580 million, according to the Federal Election Commission, a mere one-quarter of 1 percent of the $306 billion raised for charity.
