The life stories of elderly activists shows that this activism has to be linked to types of explanations. On the one hand, this activism has to be read as the product of the exclusion from other organizations that these members have experienced due to their age. On the other hand, this activism has to be read as the product of their will to be committed with people from the same generation. Therefore elderly organizations are less a place where elderly interests are defended than a place where elderly people can continue some kind of activism. Finally, this paper demonstrates that the comprehension of where elderly people get involved as activists has to be linked with the structure of inequality (i.e. age segregation) that exists in social movements as in the whole of society.
