A statistic is either a fact or a falsehood it can’t be an opinion.
Time Trends in Schizophrenia: Changes in Obstetric Risk Factors with Industrialization

Abstract
The frequency of schizophrenia may have increased during the early stages of industrialization and may now be declining. Early in the process of development, the illness appeared to be more common among the upper classes and later, more common in the lower classes. As with certain other diseases, the occurrence of schizophrenia may be influenced by the transition from poverty to affluence.
There is a meta analysis of 18 different journal articles that all disagree with the author’s opinion about the rate of schizophrenia over the years.
The author’s statement is his opinion. It is not fact.
Further, I have studied this subject from the period when Jung’s boss at the Burgholzli Hospital in Zurich first coined the term schizophrenia in 1911.
Bleuler had coined the term schizophrenia to replace “dementia-praecox.”
My point is that differing diagnosis resulted in much confusion over the years.
For example Bleuler had coined the term schizophrenia in 1911 to replace the diagnosis “dementia-praecox” which translates as early dementia. That’s what schizophrenia was originally considered.
