(41,453 posts)In the past few people were diagnosed as autistic, because there was little awareness of the disorder. So high-functioning autistic/Aspergers individuals were 'maladjusted', 'emotionally disturbed' or just 'odd'; and lower-functioning autistic people were just 'mentally handicapped' without qualification, or were 'childhood schizophrenics/ psychotics' (a diagnosis almost never used now).
In 2009, Simon Baron-Cohen and colleagues did a large-scale study in the UK where children, younger adults and older adults were assessed according the current criteria used for diagnosing autism. The rate was identical in the different age-groups: about 1%. The only age difference was that many of the children were already diagnosed on the autistic spectrum, while most of the adults had other diagnoses or none. Thus, there is no evidence for an actual increase in the number of people with autism.
But indeed, with regard to your last sentence, pollutants in the air and water are probably causing a lot more health problems in both children and adults than any vaccines ever did!
