In the last hundred years demographic change has altered the age composition of the overall population. In particular there was a marked rise in the number of older people (65 years and over). In Germany the proportion of the total population aged 65 years and over increased from 4.6% in 1871 to 15.1% in 1977. The current demographic-geographical situation of the proportion of the aged, homes for the aged and nursing homes in the different districts of North Rhine-Westphalia is presented. Since 1979 there has been an increase of 17,122 in the number of beds available in nursing homes. In North Rhine-Westphalia a total of 49,536 beds in nursing homes were available on 1.9.84, i.e. 2.08 beds per 100 aged (65 years and over), while the intended index is 2.3 beds per 100 aged. The number of places in homes for old people was 58,236 on 1.9.84, i.e. 2.45 places per 100 aged. The intended index (2.80 places per 100 aged) is nearly reached, although the regional differences are considerable.
在过去的一百年里，人口结构的变化改变了总人口的年龄构成。尤其是老年人（65岁及以上）的数量显著增加。在德国，65岁及以上人口在总人口中的比例从1871年的4.6%增至1977年的15.1%。本文介绍了北莱茵-威斯特法伦州不同地区老年人比例、养老院和疗养院的当前人口地理状况。自1979年以来，疗养院的床位增加了17122个。1984年9月1日，北莱茵-威斯特法伦州疗养院共有49536张床位，即每100名老年人（65岁及以上）有2.08张床位，而预期指标是每100名老年人2.3张床位。1984年9月1日，养老院的床位为58236个，即每100名老年人有2.45个床位。预期指标（每100名老年人2.80个床位）虽未完全达到，但已接近，不过地区差异相当大。
