Migrants

What is prevalence?

Prevalence measures the proportion of individuals who have a disorder at a particular point in time (point prevalence) or during a specified period (annual prevalence, lifetime prevalence) and this may vary across regions. It is distinct from incidence, which refers to how many new cases there are per population in a specified time period. Lifetime prevalence is the number of individuals in a population that at some point in their life have experienced schizophrenia compared to the total number of individuals.

What is the evidence for prevalence rates in migrant populations?

Moderate quality evidence found increased prevalence of schizophrenia in migrant populations  compared to native-born populations.
