DAE notice that the new generation are not having kids??

I was born in 1999, I’m not against having kids in fact I would love to be a mom

But yet I have none and actually none of the people I grew up with have any either except maybe a couple

When my mom was in her 20s nearly all of her friends had kids. Early 30s latest

None of my friends are against having kids, they just aren’t having any for some reason. Actually I notice most people from my generation are more worldly and are travelling all over the world

The #1 reason I don’t have kids yet is because of how expensive everything is and how much financial stress I would have …

People from my mom’s generation probably had the same worries, but yet they were popping so many kids out. Were people back then just really careless with self control? Was birth control failing? Did guys have no pull out game??
