The services for the mentally retarded follow the principle of normalization, with integration as the most important means towards achieving this goal. A total of 0.44% of the population are mentally retarded. This number is decreasing. Only 23% of these are midly mentally retarded. The number living in different forms of institutions, is given by age and grade of retardation as well as the number of integrated school classes, and the changes in these respects since 1970 are described.
为智障人士提供的服务遵循正常化原则，融合是实现这一目标的最重要手段。共有0.44%的人口为智障人士。这一数字正在下降。其中只有23%为轻度智障。按年龄、智障程度以及融合学校班级数量列出了生活在不同形式机构中的人数，并描述了自1970年以来这些方面的变化。
