Schizophrenia affects around 0.3–0.7% of the general population at some point in life (i.e. lifetime prevalence),[1] or 21 million people worldwide as of 2020 (about one of every 285).[2] By using precise methods in its diagnosis and a large, representative population, schizophrenia seems to occur with relative consistency over time during the last half-century.[3]

While it is claimed that schizophrenia occurs at similar rates worldwide, its prevalence and incidence varies across the world,[4] within countries,[5] and at the local and neighborhood level.[6] It causes approximately 1% of worldwide disability-adjusted life years (DALYs).[7] The rate of schizophrenia varies up to threefold depending on how it is defined.[1]
