A PubMed search was conducted to identify studies published at any time through September 2020 using the search terms: autism [title/abstract] OR autistic [title/abstract] AND prevalence [title/abstract]. Data were abstracted and included if the study fulfilled the following criteria: • The study was published in English; • The study produced at least one autism prevalence estimate; and • The study was population-based [any age range] within a defined geographic area.
