TY - JOUR T1 - ARchives of general psychiatry Y1 - 2011/05/01 N1 - 10.1001/archgenpsychiatry.2011.30 JO - Archives of General Psychiatry SP - 441 EP - 441 VL - 68 IS - 5 N2 - Brugha et al Article report on a general population epidemiological survey of autism in adulthood using a 2-phase strategy in England (7461 screening interviews; 618 diagnostic). The weighted prevalence was 9.8 per 1000. Prevalence was higher in men, those without educational qualifications, and those living in social (government-financed) housing. Prevalence was not related to respondent's age. Recent apparent rises in autism rates must therefore reflect better case finding rather than some new environmental toxin.
