mox: if you assume that half of the 10% decline in “centrist orthodox” was students who became more “yeshiveshe” and transferred to “yeshiva” schools you are left with only 9% growth.
Instead of guessing that the growth was understated by missing small dynamic schools, it would be logical to propose that the growth was exaggerated by more experienced surveyors discovering schools they missed 5 years earlier.
The whole premise of AZ’s argument was based on data from this one study and I have been responding based on the same assumption, if you are questioning the accuracy of the study we must reconsider all options.
