I noticed that most women have their first child at 22-24 years old, is that intentional?

I know it is anecdotal evidence, I have heard online that the average age of women having their first child is 26 (at least in the UK). Yet I have noticed that the majority of women seem to start having their children at 22-24 years old. I’m not sure how accurate this is, but from my observations and from all of the women I have met, their age seems to be the prime age for having kids. I know I am biased, but I am intentional in not having kids, I don’t think it’s a coincidence that most women have children at 22-24 years old.
