Title: Weighting Sub-Populations in Longevity Inequality Research: A Practical Approach
Author-Name: Adam Szulc 
Abstract: The weights allowing calculation of life expectancy for a whole population as a weightedaverage of group-specific life expectancies are proposed. They are characterized by aminimum distance from the actual population shares that are different from those assumed inlife tables. It is demonstrated how they may be obtained by means of constrained regression,using popular statistical/econometric software. The problem of negative solutions is alsoaddressed. The empirical examples include longevity inequality calculations under variousweighting systems. The data come from the Human Mortality Database and from Russia'sregional statistics.
