What is the geographic distribution of schizophrenia?

Answer 1

The rates of psychotic disorders are about the same all around the world, at 1.1 percent. However, highly populated places such as cities have higher rates of schizophrenia than do rural areas, as do places with more viruses. Additionally, schizophrenia is diagnosed more often in higher-income countries. Schizophrenia is rarely diagnosed in Africa, for example, although there is about the same incidence of psychotic illness there as in other places.
