 Mortality rates, life tables and life expectancy under a stationary population compositionMagdalena Muszynska-Spielauer and Tim Riffe No rnbf4, OSF Preprints from Center for Open Science Abstract: While the effect of unobserved heterogeneity on aggregate mortality patterns is well studied, an analogous effect of composition by observed characteristics is often ignored. In this research note, we propose a set of simple and general formulas to adjust period mortality rates and life tables to suppress heterogeneity imposed by the non-stationary composition of cohorts according to observed population characteristics. We also offer an approach to decompose differences in period life expectancy under a stationary composition into compositional differences and the disparity of life expectancy (LE) of the sub-groups. We illustrate this lagged compositional effect on the example of educational attainment in Denmark in 1991-1995 and 2011-2015, and discuss the effect of educational expansion on developments and sex-gap in LE. We demonstrate that the difference between LE and LE under a stationary educational composition (LEsec) in Denmark is non-ignorable: the gap accounts for up to 1.9 years in 2011-2015. The educational expansion in the study years contributed to the increase in LEsec, of which women benefited to a greater extent. Taking into account population stationary composition by observed population characteristics in total mortality rates improves our understanding of mortality at current conditions.
