At some point the geekier types either alleviate all their concerns and/or realize that a lot of great things can't be framed into a logical decision, and they make the jump. :)
How is it logical then to wait until you're older (define older!)?
Part of my decision - first child c. 30 - was not to wait any longer lest I be unable to keep up with them physically.
You want to be able to afford the increasingly higher costs of having children. You want your marriage to not be stressed from added financial responsibility. People tend to make more as they get older so many wait. That played a role in my decision to wait for sure.
The physical component you suggested is certainly a logical argument for having them younger. That pressure is higher for women too because they consider the risks of pregnancy (as you noted) and the possibility they may not be able to conceive if they wait too long.
I understand your decision but to me - having a kid at 30 over the physical concern is not logical. Sure I'd be 48 when they're 18 but even at that point, I don't have physical concerns. In fact, that would provide additional motivation to remain healthy. If I was considering physical capability for grandkids then that might enter my decision. My wife just talks about how we'd be the older parents in our kid's class which doesn't concern me.
Everyone's situation is different though. I just think finances is a big driver for those that wait and honestly I think it's a good one. If you're married and don't have your finances in order, there's a good chance your marriage won't last and you'll rack up more stress which isn't good for you or your kids.
There is more than one variable at work. My parents had me at 19. I remember the family always struggling so I decided never to have kids until I was 30 (and later just turned into never).
This finding strikes me as epiphenomenal.
Plenty of my non-geek friends with good income careers are just now trying to settle down at 30.
In parts of Italy it's very uncommon to have children before 40!
