Question

How many people worldwide are afflicted with schizophrenia?

Answer 1

WHO statistics reveal that more than `21` million people worldwide are affected by schizophrenia.

Explanation:

While statistics vary, the WHO says that more than `21` million people are affected by schizophrenia worldwide. Refer http://www.who.int/mental_health/management/schizophrenia/en/

However, at http://www.schizophrenia.com/szfacts.htm approximating the rates of prevalence across the world, it is said that around `1.1%` of the population (around `51` million people) are affected by schizophrenia. This is an approximation as prevalence and measuring standards vary from country to country.
