apushatayid: I don’t see how you can argue on basic mathematics. It is a poshut mathematical fact that if the average frum husband is older than the average frum wife, then there will be more unmarried girls than unmarried boys (and, by mathematical definition, some girls will never be able to get married — even though, mathematically, every single boy will be able to get married).
Now, you might argue that the average age of frum husbands is not higher than the average age of frum wives. If you make that argument, you can plausibly say there is no excess of unmarried frum girls compared to unmarried frum boys. But unless THAT is your argument — some husbands are older and equally some wives are older, but on average it is about equal both ways — (and I don’t think anyone will argue that on average age of husbands are not older than the average age of wives), you are essentially positing that 1+1=3.
