Thank you for your request.

Unfortunately, we do not hold the information requested.

Although mental health is captured in the question 'do you have any physical or mental health conditions or illnesses lasting or expected to last 12 months or more', we did not collect data pertaining to specific conditions in England and Wales.

NHS digital may be better placed to assist you with accurate figures for those with Autism Spectrum Disorder. Their FOI team can be contacted at enquiries@nhsdigital.nhs.uk. You may also find this publication interesting Autism Statistics, April 2021 to March 2022 - GOV.UK (www.gov.uk).
