This used to happen around the age of 14 but improved diets and overall health in much of the developed world has seen puberty start to begin as young as ten.
In most industrialized countries, the average age for a girl's first menstruation has fallen by four years in the past 150 years - half of girls now get their period by 12 or 13 years old. For example, the brain continues to mature past the age of 20, working more efficiently. Some information systems define people ages 15-19 as "adults", which will "effective render adolescence invisible".
The average age for a man to enter his first marriage in 2013 was 32.5 years and 30.6 years for women across England and Wales. This is nearly an eight-year increase since 1973.
It is a redefinition, they say, that reflects an evolving society where puberty hits earlier, bodies develop into the 20s, and where young people leave home, get married, have children and gain economic independence later than ever.
She explains that these delays mean "semi-dependency" that is characteristic of adolescence.
"Adolescence encompasses elements of biological growth and major social role transitions, both of which have changed in the past century", they write in the article, published Wednesday.
Prof. Viner supports extending the definition to cover adolescence up until the age of 24 and says a number of United Kingdom services have already taken this into account.
