目的:揭示队列期望寿命同现时期望寿命差值的分布特征及变化规律。方法:通过对5个欧洲国家(地区)51年的两种期望寿命差值的比较,运用Stata软件对其分布和变化进行描述分析。结果:按国别计算的队列期望寿命和现时期望寿命的差值在1864~1900年和1901~1914年,分别集中在3.48~6.14年和6.23~6.97年范围内。结论:两种期望寿命的差值在不同的时间段内集中趋势不同,主要与死亡率变化速度有关。在长期变化中,变动的方向和程度取决于未来年龄别死亡率和现实死亡率的差别情况。
OBJECTIVE: To reveal the distribution characteristics and variation of the life expectancy of the cohort with the expected life expectancy at the same time. Methods: Based on the comparison of two life expectancy differences of 51 years in five European countries (regions), Stata software was used to describe the distribution and changes. RESULTS: The difference between the expected life expectancy and the current life expectancy calculated by country was concentrated between 3.48 and 6.14 years and between 6.23 and 6.67 years from 1864 to 1900 and from 1901 to 1914, respectively. CONCLUSION: The differences in the two life expectancies have different concentration trends in different periods of time, mainly related to the rate of change of mortality. In the long run, the direction and degree of change depends on the difference between the future age-specific mortality and the actual mortality rate.
