A small group of researchers with the Royal Children’s Hospital in Australia is suggesting that it might be time to change the span of years that define adolescence—from the current 10 to 19 to a proposed 10 to 24 years of age. In their paper published in The Lancet Child & Adolescent Health, the group offers arguments for their suggestion and the benefits they believe would come about by doing so.
Adolescence has traditionally been defined as the period between childhood and adulthood—from puberty until the attainment of an adult role in society. Though it is not normally legally tied to rights or entitlements, it has served as a guide for those who make policy. In the U.S. and Britain, for example, the age of 18 is considered the age of consent at which people are allowed to make choices about their bodies and their role in society, and are also allowed to vote and serve in the military. In their paper, the researchers suggest that due to both physical and societal changes, it might be time to consider pushing the end of adolescence forward a few years.
Adolescence has already been pushed lower, they note. Young boys and girls develop earlier than their parents and grandparents—many girls begin menstruating, the team notes, at around 10 years of age. The norm used to be age 14. New research, they also note, shows that the adolescent brain does not stop developing until a person is well into their 20s—and many do not develop wisdom teeth until age 25.
And, the team notes, society has changed, too. In the U.K., the average age of marriage has been climbing, from the early 20s to the early 30s. And young people are leaving home later, too. In the U.K, young people on average do not leave home until they are 25 years old. Expectations by parents and others in society have also changed—many parents now expect their children to live at home longer, which has led to the realization that some policies have to change. In the U.S. for example, parents have been pushing to force insurance companies to allow adults to keep their children on their policies longer.
Extending the age of adolescence, the group claims, would help in framing laws meant to protect young people and also to help them on their path to adulthood.
