According to the National Autistic Society (https://www.autism.org.uk) "1 in 100 people are on the Autism Spectrum" and note that it is an "ever-changing definition".
An autistic person may also prefer to be known as neurodivergent. Autism is a spectrum which means everybody with autism is different and the level of support and therapy needed for an autistic person is also different.
