The aim of this work is to contribute to improving knowledge about the social, civic and political participation of older retired adults, a phenomenon with little visibility compared to other issues of ageing. An analysis of data from SHARE—Survey on Health, Ageing and Retirement in Europe (Wave 7) was carried out to understand the extent to which retired people aged 60 or over participate in four types of activity—volunteering, training, local associations, and political organizations—in 27 countries, with an emphasis on Portugal. A descriptive analysis of the results was made in order to understand the proportion of people taking part in each of the activities under study. Overall and in Portugal, local associations are the context where there is the most participation (overall: 22.6%; PT: 10.5%), followed by volunteering (overall: 13.9%–PT: 9.8%), educational contexts (overall 6%; PT: 3.5%) and political organisations (overall: 5.3%; PT: 3.2%). Gender patterns were identified when comparing the different countries and the different activities, as well as a strong tendency for participation to decrease with increasing age.
