老年型人口是指一个地区(或国家)的总人口中年龄较大的人口高于一定比例时(国际上按65岁及以上人口占总人口的比重超过7％为标准)的人口年龄构成类型。人口老龄化对社会经济和医疗卫生服务等都会产生重要的影响。研究这些问题,对制订人口政策和长远规划是很必要的。目前石河子人口年龄结构已由增长型转变为成年型。1984年人口年龄中位数为22.86岁,老年系数(65岁及以上人口占总人口的比重)为3.1％:少儿系数(0～14岁人口占总人口的比重)为29.0％。由于近年少儿系数
Aged population refers to the type of age of the population when the older population of a region (or country) is higher than a certain percentage (the international population is 65 or more and the proportion of the total population exceeds 7%). . The aging of the population will have an important impact on the socio-economic and health care services. Studying these issues is necessary for the formulation of population policies and long-term planning. At present, the age structure of Shihezi population has changed from a growth type to an adult type. In 1984, the median age of the population was 22.86 years, and the ageing coefficient (the proportion of people aged 65 and over in the total population) was 3.1%.
