Changes in the Population of Persons with Autism and Pervasive Developmental Disorders in California's Developmental Services System: 1987 through 1998. A Report to the Legislature, March 1, 1999.
California State Dept. of Developmental Services, Sacramento.
This report discusses the results of an analysis of demographic and Client Development Evaluation Record data compiled at each of the 21 regional centers in California serving individuals with autism and pervasive developmental disorders. Data covering a period of 11 years, beginning in January 1987 and continuing through December 1998, show that the number of persons with autism grew markedly faster than the number of persons with other developmental disabilities. Significantly greater numbers of persons with autism are entering the regional center system. In the past year alone, 1,685 persons with autism were taken into the system. The number of persons entering the system far exceeds the expected number determined by traditional incidence rates. Estimates suggest that, compared to other disabilities, net growth in the number of persons with autism is on average about 3 percent greater each year. Compared to characteristics of 11 years ago, the present population of persons with autism is younger, has a greater chance of exhibiting no forms or milder forms of mental retardation, is more likely to live at home, and is more likely to receive an earlier diagnosis. Appendices include the diagnostic criteria for autistic disorder, Rett's disorder, childhood disintegrative disorder, Asperger's disorder, and pervasive developmental disorder not otherwise specified.
