Added anecdata: A lot of my direct colleagues are getting married and having kids at the moment, often a bit later in life (in their and their partners 30's) than the preceding generation, but still.
Me and my siblings, none of us seem to have any inclination; combination of just not wanting them, having neurodiverse conditions that seem more debilitating than my parents' generation, and finances like only becoming homeowners in our mid 30's (and my younger sibling cannot afford a home)
There is never a good time to have kids, and so any time is a good time to have kids.
Maybe I'm a lucky one, but we took the plunge right at the end of biological possibility since we're old, and I only wish I had done this 20 years ago. It's such a wonderful experience and believe me I never would have guessed that.
There's nothing I was doing back then that mattered at all. And now I'll be lucky to see my kids graduate college because I waited so long.
In hindsight, the high school years would have been the perfect time to have children. No responsibilities, doing nothing of value, biology in its optimal state, and the greatest support network you're going to have. But at the same time I feel for those who did because I know they felt the terrible social scorn.
You spend all those years being told that having children is the worst mistake of your life, until you're in your 30s, and then all of sudden the same people are "What's your problem? Why haven't you had children already?" It's bizarre.
