Wolfe said people in less religious states “view the tax money they’re paying not as something that’s forced upon them, but as a recognition that they belong with everyone else, that they’re citizens in the common good. … I think people here believe that when they pay their taxes, they’re being altruistic.”  

Mississippi once again was among the most charitable states in the nation, ranking second behind Utah, the only non-Southern state in the top five.

In Utah, residents gave 10.6 percent of their discretionary income to charity. Mississippi was next, followed by Alabama, Tennessee and South Carolina. The least generous was New Hampshire, at 2.5 percent, followed by Maine, Vermont, Massachusetts and Rhode Island.

So what’s the secret to Mississippi’s giving ways? It could be the high percentage of religious residents.

A new study on the generosity of Americans suggests that states with the least religious residents are also the stingiest about giving money to charity.

The study released Monday by the Chronicle of Philanthropy found that residents in states where religious participation is higher than the rest of the nation, particularly in the South, gave the greatest percentage of their discretionary income to charity.

The Northeast, with lower religious participation, was the least generous to charities, with the six New England states filling the last six slots among the 50 states. Churches are among the organizations counted as charities by the study, and some states in the Northeast rank in the top 10 when religious giving is not counted.

The study also found that patterns of charitable giving are colored in political reds and blues.

Of the 10 least generous states, nine voted for Democrat Barack Obama for president in the last election. By contrast, of the 10 most generous states, eight voted for Republican John McCain.

But Peter Panepento, the Chronicle’s assistant managing editor, said that political breakdown likely speaks to a state’s religious makeup, not its prevailing political views. He noted the lowest-ranked Democrat states were also among the least religious, while the top-ranked Republican states were among the more religious.

“I don’t know if I could go out and say it’s a complete Republican-Democrat difference as much as it is different religious attitudes and culture in these states,” he said.
