Residents of the metropolitan area that includes Vancouver and Portland donated less of their income to charity than the rest of the country in 2015, according to an analysis of itemized charitable deductions.

The Chronicle of Philanthropy’s How America Gives, an analysis of 2015 itemized tax deductions for people earning at least $50,000 released Tuesday, said residents of the Portland-Vancouver-Hillsboro, Ore., metro area donated $3.5 billion to charity in 2015.

The Chronicle of Philanthropy said that 24 percent of taxpayers reported on their tax returns that they made a charitable gift in 2015, a figure that a decade prior typically reached 30 or 31 percent. What’s more, three-quarters of all itemized deductions were from taxpayers who earned at least $100,000. Most charitable giving is done by the wealthy.

“Today’s donors really need transparency and inclusion and a clear understanding of the impact their gift is having,” Spurgeon said.
