I grew up in a suburb like yours. I'm raising my kids in a suburb that's by and large the same.

The biggest difference, imo, is the number of families.

I lived on a small street with a cul-de-sac. Maybe 35 houses or so. At least half had kids aged 0-15.

I now live on a street about the same size with my kids. There is one house with ~7-10 year olds, two houses with 3-5, one house with a couple of teens, one house with a baby.

Nothing else really matters, you can't expect kid communities to self generate at these densities.
