Continuum of Intellectual Disability: Demographic Evidence for the “Forgotten Generation”

Abstract

Demographic features of Americans with mild intellectual disabilities were estimated in an analysis of the National Health Interview Survey. The cohort was compared to the population of the United States, persons with specific learning disabilities, and persons with mental retardation. Comparison on basic indices of adaptive functioning and SES suggest a large cohort of Americans who share many support needs and social and economic vulnerabilities with those labeled "mentally retarded." The combined prevalence of intellectual disability/mental retardation was estimated to be 1.27%. Implications are discussed in terms of the "forgotten generation" report of the 1999 President's Committee on Mental Retardation and evolving conceptions of mental retardation.
