Dy You are right my point 2 is not the best since it applies ot the girls I misspoke. If 11% of Girls marry their age or younger their is no age gap, but admittedly that is probably the case and is impractical. Although it does mitigate the “age gap” somewhat
as to the the fertility rate I dont want to google anything, those numbers are irrelevant since they have little bearing on frum society. The numbers that matter are frum high school graduates (These are not the actual numbers we care about but are the closest that can be accurately obtained)
At any rate my point #3 still stands. The problem is girl aren’t getting dates. This has nothing to do with the “age gap”
