A lot of K-Pop idols start their careers at young ages. Most become trainees in their early to mid-teens, and train for several years before they debut in their later teens or early twenties. These four groups, however, all have members that were born in the 2000s, meaning they’re all still 20 or less years old, and most of them debuted at least a year ago if not longer! Here are the members of those groups, their ages, and the average age of the group when they debuted.
