The CDC Prevalence Rates have been updated to 1 in 44 children have autism as of Dec.3,2021. Visit this CDC webpage for more information: https://www.cdc.gov/mmwr/volumes/70/ss/ss7011a1.htm
Interpretation: In 2018, one in 44 children aged 8 years was estimated to have ASD, and prevalence and median age of identification varied widely across sites. Whereas overall ASD prevalence was similar by race and ethnicity, at certain sites Hispanic children were less likely to be identified as having ASD than White or Black children. The higher proportion of Black children compared with White and Hispanic children classified as having intellectual disability was consistent with previous findings.
