Lubavitch Russian dropouts?

Estulin, Mishulovin, Okunov, etc. Are Russian Lubavitcher families more prone to attrition? From physiological prospective this would be logical as the gap between parents and children who were born here must be above the average. Is there a pattern? Also as this seems to be a wide spread phenomena affecting many families, is there an attempt at community response? Or perhaps the only response is to tell a curious bocher to see a shrink and then to expel him/her from a Yeshiva?
