 The year of 2017 was one special year in K-Pop history because there were numerous debuts, more debuts than ever before.

A lot of boy groups and girl groups were born and among them, some were able to draw attention and gained huge fandom in a brief period. As K-Pop is loved all around the world, even the groups just debuted are appealing to fans abroad if they've got great music and energy. It's amazing to see how fast each group is growing each day, not only inside Korea but outside as well.

Another amazing fact about their debuts is the average age of the idols. It just gets younger every day! Though we were aware of the fact that idols debut at early ages, it's quite surprising to see such young people performing so perfectly.

Here is an average age chart. As you go through it, recall their performance. You'd probably realize their great work at such young age!
