PY: It is difficult to get data on boys since HS don’t keep good updated info. The only data that I have access to so far is BMG where 5 years after starting to date (equivalent of 24 year old girls) fewer than 2% are still single. In addition Shadchanim report not having to many older boys but that’s not a scietific method.
