The report, released at the recent American Academy of Religion conference in Baltimore, found that in 2012:
• 63 percent of all Americans donated to some kind of cause, charity or philanthropy.
• 71 percent of those donors gave both to religious groups (including congregations) and to nonreligious organizations.
• Any given follower of one religious tradition is no more likely to give to charity than a follower of another faith.
Differences in the likelihood of giving are due more to variations in household income, education and age, said Landres.
When the study looked at amounts donated overall in 2012, researchers found:
• The median amount given among all donors was $660.
• 41 percent of all household dollars donated went to religious congregations.
• 32 percent of donated dollars went to religiously identified nonprofits such as Catholic Charities or Jewish Federation or small programs such as the University Muslim Medical Association Community Clinic in Los Angeles, Landres said.
This aligns with research by Calvin College sociologist Jonathan Hill, who studies religion and financial generosity.
"Giving is a transferable habit that happens to be cultivated in religious settings," Hill said at the recent Society for the Scientific Study of Religion conference in Boston.
But the "Connected to Give" report also cites generosity thriving among people who claim no religious identity: 34 percent of these "nones" nonetheless give to religiously identified organizations.
Until now, most studies have defined "religious giving" as donations to religious congregations for specifically religious activities. It didn't count as "religious giving" if you gave to a church's soup kitchen, say, or to a combined-purpose group doing secular work such as the evangelical relief group World Vision.
The label also wouldn't have covered several of the projects listed in the ninth annual "Slingshot Guide" a handbook of nonprofit programs and projects that reflect Jewish values of prayer, study and good works. It was created to appeal to young Jews who often don't participate in traditional Jewish philanthropic institutions.
The 2013-14 edition of the "Slingshot Guide" includes programs such as Innovation: Africa, which uses Israeli technology to bring "light, refrigerated medicine and clean water to nearly half a million Africans," and the Sunflower Bakery in Gaithersburg, Md., where people with disabilities learn job skills baking kosher pastries.
The "Connected to Give" report was drawn from the National Study of American Religious Giving, sponsored by Jewish foundations and federations, and the philanthropy research organization Jumpstart.
Landres, who is also CEO of Jumpstart, said in an interview that the research had two purposes. One was to widen the understanding of who gives, why and where they give. The second was to wedge open new sources of venture capital to groups that had been shut out because they were religiously identified.
It's a real issue: There are major funders that will not award grants to groups that they fear may proselytize or promote a specific religious view, he said.
"Not everyone is trying to spread their faith in their work. We think any group, religious or not, that can show they can get the work done and have the ability and moral obligation to do it well, should be heard," said Landres. "Giving is personal. People give as whole individuals and should not have to check their motivations at the door. Those who are motivated by their faith to do good in the world deserve a seat at the funding and policy tables."
