Charitable giving nationwide rose by 4.1 percent last year to a record total of $373.3 billion, bolstered by an ongoing national economic recovery and stabilizing household finances, according to an annual report by the Giving USA Foundation.

“The last two years represent the highest and second-highest totals for giving in the past 10 years, adjusted for inflation,” said Amir Pasic, the dean of the Indiana University Lilly Family School of Philanthropy in Indianapolis, which provided research for the report.

While gifts to religious groups have declined as an overall share of total giving in recent decades, last year’s amount was about the same percentage as in 2014, Giving USA said.

Among the big donations last year, according to a separate report from The Chronicle of Philanthropy, were $100 million from Roberta Buffett Elliott, a sister of financier Warren Buffett, to Northwestern University to establish the Buffett Institute for Global Studies; and $75 million from Facebook co-founder Mark Zuckerberg and his wife, Priscilla Chan, to the San Francisco General Hospital Foundation to support an acute-care and trauma center.
