Erwachsenenalter vs Jugend
youth
'die Jugend' and 'das Erwachsenenalter' are opposite stages of life. 'die Jugend' is the time between childhood and being an adult. 'das Erwachsenenalter' begins after that, when a person is considered an adult. So the contrast is: not yet adult on one side, adult on the other. You use 'Jugend' when talking about this earlier period of development, and 'Erwachsenenalter' when referring to life as an adult.
Erwachsenenalter

Jugend
In der Jugend probieren viele Menschen verschiedene Hobbys aus.
In their youth, many people try out different hobbies.
