Question to the Department of Health and Social Care:

To ask the Secretary of State for Health and Social Care, what assessment he has made of the prevalence rate of autism amongst the compulsory school age population in England in the latest period for which that data is available.

The Children and Young People Mental Health Survey dataset for 2017 reports an estimated autism prevalence rate of 1.5% amongst children aged five to 10 years old and 1.2% amongst children aged 11 to 16 years old.
