Prevalence:
Estimates of the prevalence vary markedly depending on the stringency of the definition used.

  • Wing and Gould (1979)
    Prevalence rate of 0.6 per 10,000 children with a combination of Asperger's Syndrome and Mild Mental Retardation
    Aditional 1.1 per 10,000 children who had been autistic in early life but later showed features of Asperger's Syndrome

  • Swedish Epidemiologic Study (Gilberg and Gilberg 1989)
    10-26 per 10,000 children with normal intelligence rate
    Additional 0.4 per 10,000 Swedish teenager had a combination of Asperger's Syndrome and Mild Mental Retardation

Sex Ratio:
Asperger originally reported the condition only in boys but Wing reported the condition in girls as well. There does appear to be a male predominance, ratios ranging from 3.8 to 10.5 boys to every girl.

Social Class:
A trend towards greater prevalence in higher class has been noted, which according to Wing might be a result of greater awareness and hence a tendency to seek more services from special clinics compared to lower classes.
