New research from the Women’s Philanthropy Institute (WPI) at the Center on Philanthropy at Indiana University finds that women from virtually every income level are more likely to give to charity and to give more money on average than men, after controlling for education, income and other factors that influence giving.
“Looking at giving across five different income groups, which range roughly from $23,000 to $100,000 a year, it is clear that it is not only wealthy women who give,” said Debra J. Mesch, Ph.D., director of the Women’s Philanthropy Institute. “Women across nearly every income category give significantly more than their male counterparts – in many cases, nearly twice as much.”
The Women Give 2010 report finds that "In every income bracket except for one, women give more than men. The most dramatic differences are in the lowest, middle, and highest brackets where women give almost double the amount of men. The exception is women in the second lowest income bracket ($23,509 to $43,500), who give 32 percent less than men."
Notably this research was done in households of single people to isolate the gender differences in giving. Giving in married or partnered households was not examined.
However in an attempt to make the data applicable to the partnered/married households the researchers compared never married women to never married men and found that women are almost 10% more likely to give than men. Then comparing divorced females to divorced men, women are 21%
more likely to give than men; comparing widowers to widows, women are 6% less likely to give than men.
