DaMoshe: I’m not. I’m relying on one of the most eminent MO rabbi with one of the largest congregations in one of the most prominent MO towns.
You may wish to nitpick what he said but regardless of the particulars of any survey or scientific poll, or lack thereof, the fact that he with his intimate knowledge of the community could publicly make the case that 50% of MO post-high school students go OTD, and lament that terrible situation, means the figure or general situation is minimally plausible, and more likely, given he being in a better position than most to comment about the subject, fairly close to reality.
