Taking a closer look at Giving USA's report on 2014, the Los Angeles Times notes arts philanthropy saw the biggest percentage increase, up over 9%.
"Americans’ donations to arts and culture rose 9.2% in 2014, the highest increase in nine categories tracked by Giving USA, an annual report on charitable contributions. Overall, however, arts and culture commanded a modest share of the philanthropic pie. Estimated gifts to arts and culture totaled $17.2 billion, according to the report compiled by Indiana University’s Lilly Family School of Philanthropy. Although that was a record high, it represented only 4.8% of the $358.4-billion total." -- Mike Boehm, the Los Angeles Times
