Goody 613: Please explain how arranged marriages will alleviate the problem of their being more girls in the dating pool than boys. As the Letter form over 70 Roshei Yeshiva states, the problem is a result of having more girls in the available pool than boys, which is directly is caused by AGE GAP.
Ronrsr: See what was just written. Having more than 10% of girls never getting married is at the very least a crisis. If you have time do some research on HS and their alumni. The data of alumni still single at 30 and above should make anyone shriek. (The boys have less than 2% single after 5 yrs of dating).
Mybat: This problem is not limited to the yeshvish community in the slightest. One difference in the Yeshiva community is that they typically larger families and thus age gap creates a higher discrepancy of numbers.
