Abstract

In this technical report, we present an application of the stepwise replacement algorithm for the decomposition of a change in an aggregated index by age with an additional split by mortality and population composition effects, and for the decomposition by age and country group. The method is detailed in Timonin et al. (2016). As the index to be decomposed, we use the variance in life expectancy at birth across countries. However, the scripts can be easily modified for the decomposition of other aggregate demographic measures calculated for a set of countries. In addition to the variance across the whole set of countries, we also calculate and decompose variances between and within groups of countries.
