AZ, unsure but it is irrelevant.
If I had to guess I’d say there are more girls (though I and my family know of more boys so I cant be sure) simply because Men tend to marry women younger than they.
Though as explained at length this has little to nothing to do with the “crises” in its current form which stems from the fact that women aren’t getting dates in spite of the fact that there are plenty available.
Now your turn to answer a question or 2, why would chassidim not have this “crises” Is it because they marry the the same age or their numbers arent increasing?
Similarily why the sudden talk of “Crises” which of the above variables changed?
