It's both. People are delaying the decision to have kids until later in life, then if they decide they want them they often can't have them because of fertility issues. It's more on the side of "don't want to have kids" than it is infertility, but the contribution of infertility isn't insignificant.

A couple of confounding factors would be that parents rated executive functioning skills of the preschoolers vs a test (if possible researcher blind) to look at various executive functioning skills. Another would be that parents who advocate impulse control have normal weight kids and those who don’t have overweight and obese kids since brains grow based on how our parents and environments shape us. An example of this would be parents who make kids wait until dinner to eat and don’t allow endless snacks, maybe the child has to choose between candy or a soda. This would help children develop executive functioning skills. Parents with obese kids may not have limits around food, causing the skills not to develop (ie are you hungry or bored when you want a snack).

Was just saying to my friends the other day “ You know what we don’t have enough of? “, “People, not enough people on this planet, let’s put our heads together and bring all sorts of science disciplines to bear on the problem of their not being enough people “.

In the hypothetical scenario where we were able to drastically slow down aging, having technology to also extend the length of human fertility would be fantastic.

Without it, someone living until 500 would still feel pressure to have kids when they're 20-40. However, with it they could easily space out any kids they have over their longer lifespan, likely leading to a healthier population.
