America’s slowly crawling out of the great recession.
On average, we’re earning more.
Researchers wondered how the increased income affected charitable giving.
So they dove into IRS data from 2006 to 2012.
They broke the data down by state, county, metropolitan area, and zip code.
The results—180 billion philanthropic dollars in 2012—covered about 80 percent of individual donations to charity.
The investigators found that even though wealthier Americans, defined as those making more than 200,000 a year, were making more in 2012 than they did in 2006, they actually decreased their donations by an average of almost 5 percent.
Middle-and lower-income Americans, defined as people making less than 100,000 a year, increased their charitable giving by almost the same nearly 5 percent.
This increase came despite the fact that that group was earning less, on average, than they had in 2006.
The findings are in the Chronicle of Philanthropy.
Even though the wealthiest Americans have decreased their donations by percentage, they still gave more than four a half billion dollars more in 2012 than they did in 2006.
That’s because the wealthiest Americans captured nearly all of the recession recovery.
They’re doing more than a trillion dollars better than they did six years earlier, in a rare case of a rising tide lifting only some boats.
