TL;DR
The incidence of research-identified autism increased in Olmsted County from 1976 to 1997, with the increase occurring among young children after the introduction of broader, more precise diagnostic criteria, increased availability of services, and increased awareness of autism.
Abstract
The incidence of research-identified autism increased in Olmsted County from 1976 to 1997, with the increase occurring among young children after the introduction of broader, more precise diagnostic criteria, increased availability of services, and increased awareness of autism. Although it is possible that unidentified environmental factors have contributed to an increase in autism, the timing of the increase suggests that it may be due to improved awareness, changes in diagnostic criteria, and availability of services, leading to identification of previously unrecognized young children with autism.

There is evidence that the broadening of the concept, the expansion of diagnostic criteria, the development of services, and improved awareness of the condition have played a major role in explaining this increase, although it cannot be ruled out that other factors might have also contributed to that trend.

622 Citations2002Lorna Wing, David Potter
The evidence suggests that the majority, if not all, of the reported rise in incidence and prevalence of autism in pre-school children is due to changes in diagnostic criteria and increasing awareness and recognition of autistic spectrum disorders.

The findings of a survey that found a rate of 34 per 10000 for autism spectrum disorders (ASDs) among 3to 10-year-old children in metropolitan Atlanta suggest that these differences might reflect new diagnostic criteria for autism and increased availability of developmental disability services for children with autism in the 1990s.
