I agree with Popa, there is very shaky data behind the “crisis”. To see NASI explain the “crisis” in their own words see here http://www.theyeshivaworld.com/coffeeroom/topic/there-is-no-shidduch-crisis
I am picking out one choice quote (sorry I don’t know how to italicize)
The shidduch crisis and age gap concept, were NOT discovered by a statistical analysis of how many girls are still single post 28 years old or whatever arbitrary age we would like to use, and contrasting that with the number of older boys who are single. It is almost impossible to accurately count the total number of singles at any given time.
Papa there we have it: the crisis is based on “overwhelming anecdotal evidence”.
forget about all those silly numbers
