The Occurrence of Autism

Autism afflicts approximately 5 children per 10,000. Ritvo et al. (1989) has indicated a genetic basis in autism, but it is not considered a causal factor in the etiology since none has yet to surface. Ritvo et al. (1989) cited 20 families out of 207 having more than one autistic child. They also noted that there is no correlation between autism and racial makeup, religious affiliation, parental employment and education (Ritvo et al., 1989).
