Youth is a socially constructed intermediary phase, but often means the time between childhood and adulthood (maturity). It is also defined as "the appearance, freshness, vigor, spirit, etc., characteristic of one who is young". Its definitions of a specific age range varies, as youth is not defined chronologically as a stage that can be tied to specific age ranges; nor can its end point be linked to specific activities, such as taking unpaid work or having sexual relations. An individual's actual maturity may not correspond to their chronological age, as immature individuals can exist at all ages.Youth research has come to define youth through personal experience, especially in terms of an individual's level dependency, which can be marked in various ways according to different cultural perspectives. Personal experience is marked by an individual's cultural norms or traditions while a youth's level of dependency refers to the extent to which they still rely on their family emotionally and economically.
