Decomposing dimensions of mortality inequality

Abstract

This paper demonstrates how an existing mathematical decomposition technique can be used to understand mortality inequalities across populations. The use of Singular Value Decomposition to extract key mortality patterns by age and respective relative weights across populations is discussed. This method is demonstrated through decomposing mortality by US state to highlight the main dimensions of mortality inequalities, and finds: 1) that majority of differences in mortality age schedules across states in recent years is due to differences in young-adult mortality; and 2) that relatively high-mortality states have evolved in a fundamentally different way to low-mortality states over time. This decomposition approach is complementary to existing methods to describe and summarize mortality patterns, focusing on key dimensions of mortality differences.
