一、银色浪潮冲击世界人口老龄化是世界性变化趋势,这是人口发展规律中必然出现的现象。在发达国家,65岁及以上的人口数超过该地区或国家总人口的7％,就称为老年型地区或老年型国家;在发展中国家60岁及以上人口数超过该地区或国家总人口的10％,就称为老年型地区或老年型国家。世界人口老化开始于欧洲。法国在1866年65岁及以上的老年人口系数即达7.2％,成为世界上第一个老年型国家。但在1895年以后趋于平衡。到十九世纪末,挪威、瑞典也陆续进入老年型行列。1950年
First, the impact of the silver wave on the world’s population aging is a worldwide trend, which is an inevitable phenomenon in the law of population development. In developed countries, the population aged 65 years and over exceeds 7% of the total population in the region or the country as geriatric or senile countries; in developing countries, the population aged 60 and over exceeds the total population in the region or the country Of the 10%, known as the elderly or elderly-type countries. The aging of the world’s population starts in Europe. In 1866, the coefficient of the elderly population aged 65 and above in China reached 7.2%, making it the first elderly country in the world. But tended to be balanced after 1895. By the end of the nineteenth century, Norway and Sweden were gradually entering the age-old ranks. 1950
