Life Expectancy Improvements by Age, Class, and Mortality Chapter in France, Czechia, and the United States

Abstract

Using the decomposition method, this article examines the dynamics of life expectancy. Three developed countries with relevant differences, Czechia, France, and the United States, were chosen for analysis in order to highlight similarities and differences. The analysis covers more than 40 years, 12 age groups, and 20 mortality chapters. The results reveal a pattern: first, mortality at birth improves; then the survival of lives under 65 increases; finally, improvements come from extending the life of seniors.
