Period and cohort life expectancy correspond to mortality information from a given year or from one specific cohort. Although widely used, they have limitations, and their time-trends show disparities. If the interest is to know the mortality experience of a population, these two measures will hide the historical mortality path experienced by all cohorts present at a given time. The Truncated Cross-average Length of Life, or TCAL, is a period measure including all available cohort mortality information, irrespective of whether or not cohorts have complete data. This demographic tool is particularly useful for comparing cohort mortality between populations, and in this project we extend it to comparisons by causes of death. The strength of the approach is that it allows us to identify mortality differences in cohorts which are currently alive, as well as to identify which ages and which causes of death contribute to the mortality differentials between populations.
