yes but aside from that i truly believe its higher than estimated. especially SzA. ive read many places that certain populations within programs or services people are SzA over Sz in some city programs in certain places ETC. that alone i think is a factor. i believe most people with Sz are far from being a textbook case besides even being close to one. with the criteria changed in the new DSM many people who are SzA will goto bipolar 1 or so on and some with SzA will goto Sz. that changes it too.

with that said - how one persons social life for example affects them will affects someone else differently and if a doctor isnt able to see that - that someone can fall off the Sz radar and seem more "mild". weve all had expereinces with doctors not understanding how much things affects us right? so thats prevalent as well. also can be seen the same for acadamecs/work and other diagnosable criteria.
