Findings from the Minnesota Autism and Developmental Disabilities Monitoring Network (MN-ADDM) help us to understand more about the number of children with autism spectrum disorder (ASD), the characteristics of those children, and the age at which they are first evaluated and diagnosed.

1 in 44

or 2.3% of 8-year-old children in an area of Minnesota were identified with ASD by MN-ADDM in 2016

This is higher than the average percentage identified with ASD in 2016 (1.85%) in all communities in the United States where CDC tracked ASD data in 2016.

What are the key take-away messages?
  • Minnesota identified the third highest prevalence of ASD in the ADDM Network.
  • In Minnesota, there were differences between percentage of boys and girls identified, with more boys being identified than girls. This is consistent with previous estimates and other states in the ADDM Network.
  • MN-ADDM findings also reveal no differences in ASD prevalence across racial and ethnic groups in Minnesota. The small number of children in some of these groups makes it difficult to determine whether ASD prevalence is truly different across groups. MN-ADDM will continue to track ASD prevalence and use this information to address health difference between groups in Minnesota.
  • Although ASD can be diagnosed as young as 18 months of age, MN-ADDM is identifying children with ASD at much later ages. MN-ADDM will continue to work with the community to promote regular developmental screening and early identification.
How can this information be useful?

MN-ADDM’s findings can be used to:

  • Promote early identification of ASD;
  • Plan for the service needs of individuals with ASD and provide trainings related to ASD for healthcare providers and families;
  • Guide future ASD research; and
  • Inform policies promoting improved outcomes for people with ASD.
How and where was this information collected?

MN-ADDM information is based on the analysis of data collected from the health and special education records of children who were 8 years old and living in parts of two counties in 2016.

  • Tracking area
    Parts of Ramsey and Hennepin counties, including Minneapolis-St. Paul
  • 8-year-old children in tracking area: 13,728
    • 42 % white
    • 27% black
    • 15% Hispanic
    • 15% Asian or Pacific Islander
    • 1% other
