For the record, I disagree with "delusional disorders being quite rare"; I believe D is somewhere between 0.5 and 0.8. Certainly, only 3% of these are "serious", but I could fill a book with all of the ways people believe something that isn't true.

What sort of beliefs are you talking about here? Are you classifying simply being wrong about something as a "delusional disorder"?

Exhibiting symptoms often considered as signs of mental illness. For example, this says 38.6% of general people have hallucinations. This says 40% of general people had paranoid thoughts. Presumably these groups aren't exactly the same, so there you go: between 0.5 and 0.8 of the general population. You can probably pull together some more studies with similar results for other symptoms.
