“Youth transitions remains one of the most prominent and important concepts in the context of youth studies (…). In literature focusing on youth transitions made within Western (de)industrialised societies, the concept is used to represent a period for youths of physical and social change that falls between childhood and adulthood in the life course. But there is no consensus in regard to the age at which a youth transition from childhood begins and when it ends with the conferment of adult status.”
