This report contains 1922 statistics of schools and classes for feeble-minded and subnormal children. With regard to administration, three types of schools for mentally defective children are represented in this report: (1) State institutions; (2) private institutions; and (3) city day schools. This year (1922) the statistics show a total of 214 schools or classes for the mentally defective. About one-half of these, or 133, are classes in city day schools, 51 are State institutions, and 30 are private institutions. Since 1900 the number of State institutions reporting has increased from 19 to 51, and the number of private schools from 10 to 30. No data, on special classes in city day schools for retarded or subnormal children were collected prior to 1913. Since that date the number of cities making special provisions for these subnormal children has increased from 52 to 133. The increase in the total number of schools for mental defectives since 1900 does not show that a greater percentage of children are becoming mentally defective from year to year, but rather indicates a growing interest on the part of cities, States, and private organizations in making provision for this unfortunate club of mentally retarded or defective children.
