Garden variety.. typical ….nondescript. The typical bais yaakov with another name added like Tifferes BY or Chedvas BY or Bnos BY
The age girls return is 19 or 20 ish. Puts them about 2 years post bais yaakov and they are on the market. The boys start at 20 after 2 or 3 yrs away learning in Eretz Yisrol or elsewhere and up. Late bloomers.
My point was currently there are more girls being produced by the system than the number of boys coming out of the same system. You can them add the boys taking a little longer to get in the parsha.
The real problem is unrealistic expectations and more than enough responsibility ( not blame ) to go around.
