A report by the Indiana University–Purdue University Indianapolis’ Women’s Philanthropy Institute discovered that men and women differ in their charitable giving and volunteering habits. Based on the three groups studied (i.e., single men, single women, married couples), single women are more consistent in giving than single men and married couples. Single women are also more likely to volunteer than single men, as are married couples. The trend also extends to the retirement years. After retirement, single women increase their volunteering habits, Single men, however, are less likely to volunteer their time.
