Hope GB is proud to work in partnership with the Torfaen Autism Stakeholder Group, to host a further conference in South Wales, Autism – The Journey. Autism is much more common than many people think. There are around 700,000 people on the autism spectrum in the UK – that’s more than 1 in 100. If you include their families, autism is a part of daily life for 2.8 million people. Autism doesn’t just affect children. Autistic children grow up to be autistic adults.
