With the data from the SAHWA Youth Survey 2016 (2017), this chapter presents a study of the degree and types of political and religious participation—as well as the links between one and the other—of young people from five Mediterranean Arab countries (Morocco, Algeria, Tunisia, Egypt and Lebanon). In politics, four types of participation are distinguished: official, everyday, community and protest. Between 5% and 17% of respondents could be considered hyperactivists, by participating in three or four of these types, while for around a third there was no participation whatsoever. On the other hand, the majority of young people considered themselves very religious and, in three of the countries, a third would attend the mosque at least three times a week. But levels of religiosity did not influence political participation, since even the most religious were in favour of separating politics and religion.
