NEW YORK — GivingTuesday raised a record $3.1 billion in 24 hours for charitable causes in the U.S. earlier this week, as the event that started as a hashtag in 2012 celebrated its 10th anniversary and its status as a staple of fundraising for nonprofits, the group’s leader said Wednesday.

Despite the difficult economic year that many households have experienced, with inflation in the costs of basic goods, gas and housing, people were still willing to give, said GivingTuesday CEO Asha Curran.

“That’s really what we saw yesterday,” she told The Associated Press. “That whatever it is that people are experiencing, they were as generous as they had the capacity to be.”

GivingTuesday estimated that giving increased about 15% from 2021’s $2.7 billion, outpacing inflation. Donations were tallied using an array of data sources that includes major community foundations, companies that offer fundraising software, the payment processor PayPal and large grantmakers like Fidelity Charitable and Vanguard Charitable. Their methodology for compiling the estimate seeks to eliminate duplicate data points, Curran said.

In another measure of the resilience of donations, Fidelity Charitable said Tuesday that for the first time since 2018, the value of grants from its donor advised funds exceeds the value of investments going into the funds.

The organization said this year’s totals marked the largest amount donated on the Tuesday after Thanksgiving since the group started tracking it.

The hashtag to promote fundraising on the Tuesday after Thanksgiving started in 2012 as a project of the 92nd Street Y and the organization GivingTuesday became an independent nonprofit in 2020.
