I mean I think it depends on the suburb. If you moved your family to a place where everyone is a shut-in boomer (vs the grandfatherly types that I somehow meet in my area) then... why would you move there to have kids?
To me that's like going to a badly reviewed restaurant and then complaining about the food. If you knew you were moving to a place hostile to kids, why move there?
With the housing market competitive as it is you don't really get to much of a choice and it's not like there's yelp reviews for neighbors.
