This information is based on the analysis of data collected from the health and special education records of children who were 8 years old in 2014. In addition to the race/ethnicity categories routinely studied by CDC, in MN we are interested in understanding prevalence for Hmong and Somali immigrant populations.

Key Terms

Prevalence

Prevalence is a scientific term that describes the number of people with a disease or condition among a defined group at a specific period in time. Prevalence is usually expressed as a percentage or proportion of the defined group. For this project, we counted the number of 8-year-olds in 2014 who were identified with ASD and then divided that number by the total number of 8-year-olds in our surveillance area during 2014.
