I am looking for Statistics. Any stats on Avoidants. For example. Is there an area of the world that seems to produce more Avoidants than others?

I have found that they are not just here in the US, but everywhere. I wonder how well other countries are at diagnosing Avoidants. In many cases, its not even a given here that Avoidants will receive a proper diagnoses.

Any stats would be good.
