Sam I AM: The chassidim have a slight reverse problem. Meaning the boys are the ones having the difficulty with shidduchim. It is based on the same age gap concept in reverse.
By chassidim boys date at 18/19 the same age as the girls. (this causes the boys to have a problem because there are actually slighlty more male births each year than female births. This is actually a slight mitigating factor in the shiddcuch situation by the non chassidishe but not nearly enough to alleviate the population growth x dating age problem.
Which non chasidishe communities? ALL. YU connects is quite active in their community. NASI activites and ideas would help all segments of the community.
