AZ,
It has clearly been established that there are not more young women of marriageable age alive than men. So all you are left with is the growth factor and the age gap. Once you are working upon the assumption that there are an equal amount of men and women (1:1), then for every unmarried woman there is an unmarried man. The age gap not withstanding. The only affect the age gap does, is force some of the women to WAIT longer than they would otherwise have ideally liked to before getting married. It does not leave them unmarried indefinitely.
Additionally (and this point is separate from the previous one), so long as there is ANY frum normal male (in any particular age group) seeking to get married, no unmarried woman (in the equivalent age group) can claim she is unable to get married due to a lack of any candidate for marriage. And we know that (unfortunately) there ARE normal men in EVERY age group that are unmarried seeking to get married.
So to claim that the shidduch crisis is more pronounced for women than for men, is absurd. And the crisis is mainly that of couples marrying later than the ideal, not G-d forbid there being a very large number of people who remain unmarried all their lives.
