Abstract
This article provides a review of substantial findings and methodological issues in epidemiological surveys of autism. Studies published since 2 000 are reviewed and indicate huge heterogeneity of methods across surveys. Prevalence estimates vary widely, with a range of prevalence from 0.7 % to 1.5 % being consistent with recent, well-designed studies. Factors that explain time trends in prevalence are examined, including changes in diagnostic concepts and criteria, diagnostic substitution and improved awareness and case ascertainment. Finally, we review how factors such as social class and ethnic minority status affect prevalence in subgroups.
