Definition of "youth"
ACYS defines youth as people aged 10 to 24. This age range is also used by the Australian Medical Association and the World Health Organisation. 10 to 24 is also the age definition used by the Australian Medical Association.
However, "the definition used by other organisations and other countries varies a great deal. The by-laws of the Youth Development Association in the Federated States of Micronesia, for example, define youth as between the ages of six and 35 (or more than 70% of their population). The Southern African Zonal Youth Forum recently extended their 18?26 youth age range to 18?30 years, reasoning that all their existing youth organisations had an upper age limit of 30 or 35 and the school-leaving age was 20. Concepts of age in regard to legal rights and responsibilities is another area open to anomaly. The various states of the United States exemplify this, such as Oklahoma where the law allows a 16-year-od to be sentenced to death but not to buy alcohol until the age of 21".(Sheila Allison, Editor of Youth Studies Australia, September 1999.)
