Youth is the time of life when one is young, and 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 without consent.
Youth is an experience that may shape an individual's level of 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 means the extent to which he still relies on his family emotionally and economically
Around the world, the English terms youth, adolescent, teenager, kid, and young person are interchanged, often meaning the same thing, but they are occasionally differentiated. Youth can be referred to as the time of life when one is young. This involves childhood, and the time of life which is neither childhood nor adulthood, but rather somewhere in between.Youth also identifies a particular mindset of attitude, as in "He is very youthful". For certain uses, such as employment statistics, the term also sometimes refers to individuals from the ages of 14 to 21.However, the term adolescence refers to a specific age range during a specific developmental period in a person's life, unlike youth which is a socially constructed category.
The United Nations defines youth as persons between the ages of 15 and 24 with all UN statistics based on this range, the UN states education as a source for these statistics. The UN also recognizes that this varies without prejudice to other age groups listed by member states such as 18–30. A useful distinction within the UN itself can be made between teenagers (i.e. those between the ages of 13 and 19) and young adults (those between the ages of 18 and 32). While seeking to impose some uniformity on statistical approaches, the UN itself is aware of contradictions between approaches in its own statutes. Hence under the 15–24 definition (introduced in 1981) children are defined as those under the age of 14 while under the 1979 Convention on the Rights of the Child, those under the age of 18 are regarded as children. The UN also states they are aware that several definitions exist for youth within UN entities such as Youth Habitat 15–32 and African Youth Charter 15–35.
