Abstract

We provide a systematic review of epidemiological surveys of autistic disorder and pervasive developmental disorders ( PDDs ) worldwide. A secondary aim was to consider the possible impact of geographic, cultural/ethnic, and socioeconomic factors on prevalence estimates and on clinical presentation of PDD . Based on the evidence reviewed, the median of prevalence estimates of autism spectrum disorders was 62/10 000. While existing estimates are variable, the evidence reviewed does not support differences in PDD prevalence by geographic region nor of a strong impact of ethnic/cultural or socioeconomic factors. However, power to detect such effects is seriously limited in existing data sets, particularly in low‐income countries. While it is clear that prevalence estimates have increased over time and these vary in different neighboring and distant regions, these findings most likely represent broadening of the diagnostic concets, diagnostic switching from other developmental disabilities to PDD , service availability, and awareness of autistic spectrum disorders in both the lay and professional public. The lack of evidence from the majority of the world's population suggests a critical need for further research and capacity building in low‐ and middle‐income countries.

  • The prevalence of autism spectrum disorder (ASD) has surged, with an estimated 1 in 36 eight-year-olds in the United States meeting criteria for ASD in 2020.

    “The prevalence of autism spectrum disorder (ASD) has surged, with an estimated 1 in 36 eight-year-olds in the United States meeting criteria for ASD in 2020.”

    From Pharmacological treatment in autism: a proposal for guidelines on common co-occurring psychiatric symptoms (2025) · cites this paper as [2]

    The ‘Phenotypic presentation of PDD’ section (page unavailable) reports a rise in measured prevalence over time, while cautioning that changing diagnostic and case-identification practices can affect the trend. The paper does not support the specific estimate of 1 in 36 U.S. eight-year-olds in 2020; its ‘America Prevalence Estimates’ section reports earlier, different estimates. (LLM, conf=0.90)

  • The 2012 systematic review found that estimates were mainly available for children, with very few studies including populations older than 18 years of age.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
