Yearly statistics are provided to show the increase in services, programs, or personnel for the mentally retarded in the areas of training programs, special education classes, vocational rehabilitation, the foster grandparent program, and diagnostic clinics. The status of 18 programs and their financial need, the decrease in retardation due to measles, and states with phenylketonuria screening and child abuse reporting laws are listed. A map of the United States shows the location of mental retardation facilities constructed under Public Law 88-164; etiological and classification percentages are given. Ten areas needing attention are described: availability of services; manpower recruitment and training programs; use of existing resources at the community level; public-private partnerships in program development, services, and research; establishment of a national information and resource center; research and research utilization; early identification and treatment; social and institutional planning; classification of legal status of the retarded; and imaginative thinking to make new advances possible.
