Earlier today we took a look at the youngest to oldest average member ages of several different fourth generation K-Pop boy groups, so it’s only right that we compare girl groups of the same generation too! Even though these groups have all debuted within the same time frame — between around 2018 and now — the average ages of the members of some groups vary quite a bit. Here are the youngest to oldest average ages of 17 fourth generation K-Pop girl groups!
