Baby boom generation women and older donate significantly more to charity than men of the same generation, according to research recently undertaken in the US.

The Women's Philanthropy Institute at the Center on Philanthropy at Indiana University has produced a report entitled "Women Give 2012". It has found that those born in the post-WW2 baby boom (born between 1946 and 1964) give more to charity than men of the same age. The study found this was the case even when levels of education and income and other factors which might affect giving were the same between the women and men.

At all income levels, and regardless of the share of their permanent income that they give, the research found that women of baby boom age and older gave 89% more to charity than their male counterparts. Further, in the top 25% income bracket, baby boomer and older women gave 156% more than men of the same age and in the same position.

The report also found that women are more likely to give: 19% of women gave more than 3% of their permanent income to charity, compared to only 11% of their male counterparts.

The research uses data from 2003 to 2007. It has studied only households headed by single females and single males to explain gender differences in giving. The Institute explains in its research report that married couples tend to pool income and make joint decisions about giving to charity and so studying married couples does not allow for testing of gender differences in giving.
