Reminds me of this [1] post yesterday that because sedans can only fit 2 car seats parents don’t have a third child because they can’t afford a bigger car.
Maybe, parents are having less kids because they can’t afford to move to a place with an extra bedroom.

What makes you say that housing costs are the cause? I've not heard of that argument before.
