Resumen: The main goal of this research is to identify the reasons for gender differences in European volunteer rates in different types of voluntary organisations. To that end, we focus in volunteer rates at individual and national levels. We have drawn our data from the European Values Survey (EVS, 1999 and 2008). We have employed Logit models carrying out independent estimations for the individual likelihood of working as a volunteer for four categories: social awareness, professional, education and social justice. We have carried out independent estimations and we have also repeated estimations by gender subsamples. Our main result is that social factors might be even more relevant for decisions to volunteer than individual socio-economic factors. Specifying the peer group as much as possible allows better control of social variables. For example, studying the female volunteer rate is more relevant to control for the female national NGO membership rate than the total national rate. We also highlight important gender differences. For example, education is positively correlated with decisions to volunteer for both genders in all categories, but the educational effect is stronger for men in relation to professional activities and stronger for women in relation to social awareness and social justice activities.
