It has been established that under certain mortality assumptions, the current value of the Cross-sectional Average length of Life (CAL) is equal to the life expectancy for the cohort currently reaching its life expectancy. This correspondence is important, because the life expectancy for the cohort currently reaching its life expectancy, or lagged cohort life expectancy (LCLE), has been discussed in the tempo literature as a summary mortality measure of substantive interest. In this paper, we build on previous work by evaluating the extent to which the correspondence holds in actual populations. We also discuss the implications of the CAL-LCLE correspondence (or lack thereof) for using CAL as a measure of cohort life expectancy, and for understanding the connection between CAL, LCLE, and underlying period mortality conditions.
已经确定，在某些死亡率假设下，横截面平均寿命（CAL）的当前值等于目前达到其预期寿命的队列的预期寿命。这种对应关系很重要，因为目前达到其预期寿命的队列的预期寿命，即滞后队列预期寿命（LCLE），在节奏文献中已作为具有实质意义的汇总死亡率指标进行了讨论。在本文中，我们在先前工作的基础上，评估这种对应关系在实际人群中的成立程度。我们还讨论了CAL-LCLE对应关系（或缺乏这种对应关系）对于将CAL用作队列预期寿命指标以及理解CAL、LCLE和潜在时期死亡率状况之间联系的影响。
