TL;DR
The incidence and prevalence of schizophrenia have been assumed to be fixed in time but fixed in space geographically uniform since the closing years of the nineteenth century, but these assumptions are at risk of being washed away by emerging studies.

The results provide strong support for the notion that schizophrenic illnesses occur with comparable frequency in different populations and support earlier findings that the prognosis is better in less industrialized societies.

There may be significant differences in prevalence among different populations and that prevalence may change over time, and the following are suggested as areas for additional enquiry: a possible north-south gradient, special populations, and ongoing case registers in areas of suspected high and low prevalence.

83 Citations1987Erik Strömgren
Under modern treatment and care of schizophrenics the natural history of the disease is becoming increasingly different between the two sexes, and this fact, in combination with one of the hardest facts in schizophrenia research, may be useful starting points for hypotheses on aetiology, or at least necessary components of such hypotheses.

76 Citations1988John Eagles, David Hunter +1 more

Although a variety of factors influence readmission rates, the marked rise in manic readmissions suggests broadening diagnostic criteria for mania, and suggests an actual decline in the incidence of schizophrenia.

The questionable validity of the CAThGOS+ category for diagnosis of schizophrenia, the exclusion of all but one country in the incidence study, and the inclusion of brief (including culturally-related,drug, and alcohol) psychoses in their study suggest that schizophrenia has a better prognosis in developing countries are questionable.
