In this paper, I argue that both concepts of “youth” (arabic “šabāb”) and “generation” (arabic “ğīl”) are in different ways misleading and problematic when applied in empirical research on Tunisians of lower age. While they are not affirmatively used and partly even rejected by the latter, they also appear inadequate when employed as analytical categories. Instead, as I will suggest, (historical) “age cohort” is an adequate reference category that can be qualitatively described according to the shared perceptions and actions of its respective members. Thereby, the focus on self-concepts and self-narratives appears to be particularly helpful in understanding the contemporary condition of Tunisians of lower age and their social mobilization practices. It reveals, among other findings, that their movements are not primarily directed at political and social change, though conventionally assumed, but rather express a search for greater possibilities of mobility and autonomy beyond both state and societal boundaries.
