The changing role of woman in society is altering philanthropic giving, says a report by the Women’s Philanthropy Institute released Tuesday.

Young single women donors today are donating more to charity than their peers in the silent generation gave when they were young, says the report “Women Give.” At the same time, young men are giving less than male members of the silent generation gave when they were young.

The report defines “young” as those in the Gen X category, born between the early 1960s and early 1980s, as well as millennials, born between the early 1980s and the early 2000s. The Women’s Philanthropy Institute is part of the Indiana University Lilly Family School of Philanthropy. The report compares inflation-adjusted giving totals.

Young women today give an average of $244 annually, while those born before World War II gave $216 in their youth. Young men on the other hand give $344 today compared to males in the silent generation who gave $492. The institute was looking for patterns in giving between generations, rather than whether men or women give the most to charity, the report notes.

Married couples give more if the woman controls the finances and the philanthropic decisions than if the man controls them, the report says.

“Women’s changing roles within society and within the family have implications for philanthropy,” according to the report. “Nonprofit leaders and fundraisers must recognize the importance of single and married women as donors. Fundraisers who don’t know how to raise money from women simply will not be successful.”
