A systematic review of the prevalence of schizophrenia was conducted, identifying 1,721 prevalence estimates from 188 studies across 46 countries. The median point prevalence was 4.6 per 1,000, period prevalence 3.3 per 1,000, lifetime prevalence 4.0 per 1,000, and lifetime morbid risk (LMR) 7.2 per 1,000. No significant differences were found between males and females, or between urban, rural, and mixed sites. Migrant prevalence was higher than native-born, with a median ratio of 1.8. Prevalence in "least developed" countries was significantly lower than in "emerging" and "developed" countries. Studies with higher quality scores had significantly higher prevalence estimates. The review found no significant difference in prevalence estimates between urban and rural sites. Migrant prevalence was higher than native-born. Prevalence varied significantly across economic status, with lower rates in "least developed" countries. Prevalence estimates from studies with higher quality scores were significantly higher. The review found no significant difference in prevalence estimates between males and females. The median LMR was 7.2 per 1,000, consistent with previous reviews.
