生活不能自理老年人口的预期寿命及其城乡差异——基于“六普”数据分析

Urban-rural Disparity in Years of Unhealthy Life Expectancy of Chinese Older Adults Based on Sixth Census

本文基于2010年"六普"汇总数据,利用生命表技术及Sullivan法,分析了城乡老年人口预期寿命、不能自理预期寿命及其差异的变化。研究发现,随着老年人口年龄的提高,在预期寿命不断缩短的过程中其生活不能自理预期寿命却呈现小幅度的扩大趋势;各个年龄组中城镇老年人口的预期寿命及不能自理预期寿命均高于农村,但是城乡差异随着年龄的提高而缩小;城镇老年人口生活不能自理预期寿命占余寿的比重低于农村地区,而且随着年龄的提高二者之间的差异呈扩大趋势。

Based on the aggregate data of the Sixth National Population Census in 2010, using life table and Sullivanmethod, this paper analyses the changes of life expectancy （LE）, years of unhealthy life expectancy （YULE）, andtheir disparity among Chinese urban and rural older adults. The results indicate that LE decreases but YULE slightlyincreases with age. The LE and YULE among urban older adults are longer than that among rural older adults in each age, but the urban-rural disparity decreases with age. Also, we find that YULE/LE of urban older adults issmaller than that among rural older adults, and the disparity of the proportion is increasing with age.
