Women also are significantly more likely than men to give to charities (whether to medical research, disaster relief, homeless, disabled, environment, or
religion), with sex difference not being due to background factors such as age and income. The same pattern holds when we look separately at single people and married/cohabiting people. For single people, 90% of women give more than the average man (Piper & Schnepf, 2008).
On the altruistic component of prosociality, the National Altruism Study (a nationally-representative sample of Americans in the 2002 General Social Survey) found sex is strongly associated with altruistic values, altruistic behaviors, and empathy, women best men's prosociality in almost every way.
