Recent studies document that people are much more likely to donate to charity and volunteer their time when they are asked to. Using household surveys of giving and volunteering in the United States conducted from 1992 to 2001, which contain questions on whether the respondent was personally asked to give or volunteer, this paper investigates the factors associated with the probability of receiving a charitable solicitation and presents substantial evidence that race and gender differences play key roles in the selection of potential donors. In particular, males, blacks, and Hispanics are less likely to be solicited compared with females and whites. Using non-linear decomposition techniques, I find that differences in observable characteristics of individuals explain most of the racial gap in the probability of being solicited for charitable causes, but they fail to explain the gender gap in the probability of being asked to volunteer. Furthermore, these results are robust to alternative specifications. I also discuss related policy implications and argue that the economic impact of selecting potential donors based on gender and race can be considerable. Copyright Springer-Verlag 2012
