Many countries also draw a line on youth at the age at which a person is given equal treatment under the law – often referred to as the "age of majority’. This age is often 18 in many countries, and once a person passes this age, they are considered to be an adult. However, the operational definition and nuances of the term ‘youth’ often vary from country to country, depending on the specific socio-cultural, institutional, economic and political factors.
