There are more girls entering shidduchim than boys.
Maybe. We have no idea which girls do not get to the point of shidduchim within the yeshivish community or which ones go back to Israel for shana bet, put off dating for a year allowing their older sister to date, decide to finish a degree first, as well as boys coming from sources we didn’t count. We have no idea how many people consider themselves to be in shidduchim at any time or that there’s even a mismatch of numbers. That’s a whole lot of don’t know for promoting such a drastic change with no proof.
You said I misrepresented the age they were promoting. Earlier you had mentioned that NASI promotes shadchanim focusing on girls older than 19 or 20, and I mistakenly used those numbers about the age they promote for boys to get married.
