Estimates of the number of people with autism vary. A May 2005 publication of the National Institutes of Health said the best conservative estimates at that time were that 1 in 1,000 children had an autism spectrum disorder.
A May 2006 fact sheet from the Centers for Disease Control and Prevention reported that two surveys of parents estimated that 5.5 to 5.7 per 1,000 school-aged children had been diagnosed with autism.
Both of those surveys indicated that boys were nearly four times more likely to have been diagnosed with autism than girls.
Washtenaw Community Support and Treatment Services has about 648 adults with developmental disabilities enrolled in its programs, which is approximately one-third of all adults in the county with developmental disabilities.
