This is an infographic with four main pieces of information that outline the key findings of the 2014 MN-ADDM data collection. In Minnesota, 1 in 42 8 year-olds were identified with ASD. The average age at first clinical diagnosis of ASD was 4 years, 9 months. Of those children identified with ASD who also had IQ information available, 28% also had an intellectual disability. Finally, boys 4.6 times more likely to be identified with ASD than girls.
