Although I have long followed developmental theories which make these kinds of proclamations (data summaries) about % of people at various levels of development on the spectrum, my experience shows these are highly inflated numbers used typically. It may be valid that research testing shows cognitive grasp of say some new stage of development (e.g., "self actualization") --but reality is, with all the cultural barriers and the pathological and dissociative aspects in most individuals, there is a big difference to actually be able to center one's self-sense and operational values and behaviors at the new level in a deep coherent consistent integrative way--so, my estimate would be more like 0.5 % actually are living fully as "self-actualized."
