江苏中部长寿地区老龄及长寿人口分布的时空特征

Spatio-temporal characters of distribution of aging and longevity people in central Jiangsu province

目的本文以著名长寿地区且老龄化最严重的地区——江苏省如皋市、如东县及周边地区为例,从人口统计学的角度研究长寿人口分布的显著性、稳定性。方法由于以"百岁人口占总人口比重"这一方法界定长寿地区存在一定的问题,即区域人口长寿水平与老龄化程度密切相关,老龄化程度高的地区,老龄人口基数大,长寿人口也相应较多。因此,使用百岁指数和长寿指数作为研究指标,统计了2011—2015年研究区88个派出所范围内的百岁指数和长寿指数。结果通过数据分析,以如皋东部、如东和通州的部分地区最为突出,近几年该格局基本稳定。结论表明该区域长寿人口的分布存在地域分异规律。

Objective Taking famous longevity area Rugao,Rudong and the surrounding areas as an example, this paper studied the significance and stability of longevity population distribution. Methods Due to there exist some problems of ＂proportion of centenarians in the total population＂ because regional population longevity rate is closely related to level of aging, the higher aging level is, the higher longevity level is. Therefore, the CI （centenarians accounts for the proportion of people aged 65 or older） and LI （population over the age of 90 accounts for the proportion of people aged 65 or older） were taken as the research index to research longevity phenomenon of 88 police stations from 2011 to 2015. Results Through analysis of the data,regional differentiation regulation of longevity population distribution are obtained., the CI and LI were highest in several towns in eastern Rugao, and some part of Rudong and Tongzhou. Oonclusions The pattern is basically stable in recent years.
