Mop we dont!
Many don’t buy in to the “age gap theory” or at best view it as (a minor) part of the problem.
consider the following:
1) why can’t they provide real numbers it cant be that hard to ask a few schools to anonymously report how many students are in their graduating classes. We aren’t stupid we can handle numbers they claim a 4% growth rate where did this number come from? Ami magazine ran a several page “expose” on the “age gap” Not one real number was thrown out just colorful bubbles demonstrating a growth rate several magnitudes higher than any imagined by “age gap” proponents
2)Even Accepting their numbers the problem only holds true if ALL boys marry girls 3 years younger. If as little as 11% marry girls their age or older there is no “age gap” If less than that marry girls their age or older or girls a little younger than themselves the “age gap” would become an even more minor problem. Ask around this is certainly the case.
3) The shidduch process in our community works something like this: shadchan suggests girl, boy’s side looks into her, Boys side agrees, girls side looks in and agrees, they date, get engaged and married. Asking around the problem in the chain is that girls arent getting enough dates. (Generally, admitedly I dont have real data to back up this anecdotal evidence but hey neither do the :age gap” proponents).
Now going back to the numbers pushed by the “age gap” people assuming a 4% growth rate, that means 112.5 23 year olds are trying to marry 100 20 year old girls. The average guy dates 3 girls (some less some mouch more) that means 112.5 guys go on 337.5 dates. That is more than enough dates for all 100 girls. Yet the gilrs who arent getting married arent getting dates either. This cant be explained by the “age gap” at all
