Epidemiology


In a total population study of children between ages 7-16 in Goteborg, Sweden, minimum prevalence of Asperger's Disorder was 36/10,000 (55/10,000 of all boys, and 15/10,000 of all girls), and the male/female ratio was 4:1.

The prevalence of autism had traditionally been estimated around 4-5/10,000. A study from United Kingdom found the prevalence of autism at 17/10,000, and the prevalence of all Autistic Spectrum Disorders (including autism) at 63/10,000.
