As defined by the Autistic Self Advocacy Network, Autism is: a neurological variation that occurs in about one percent of the population and is classified as a developmental disability. 

While all Autistics are as unique as any other human beings, they share some characteristics typical of autism in common, such as different sensory experiences, non-standard ways of learning and approaching problem solving, deeply focused thinking and passionate interests in specific subjects, atypical, sometimes repetitive, movement, need for consistency, routine, and order, difficulties in understanding and expressing language as used in typical communication, both verbal and non-verbal, and difficulties in understanding and expressing typical social interaction.
