Abstract

Educational expansion has contributed considerably to increasing life expectancy, but its contribution to lifespan variation trends is unclear. We assessed the contributions of educational expansion and mortality changes by educational group to trends in life expectancy (⁠⁠e₃₀) and lifespan variation (⁠⁠ed₃₀) at age 30 in England and Wales, Finland, and Italy (Turin) in 1975–2015. We applied decomposition analysis to education-specific mortality rates by age and sex derived from individually linked administrative mortality data by country, educational attainment (low, middle, and high), sex, age, and calendar year. Educational expansion contributed simultaneously to increasing e₃₀ and decreasing ed₃₀ for all age groups studied. The contribution of educational expansion to the trends in e₃₀ and ed₃₀ was higher in Finland, particularly for ed₃₀⁠; it was higher among males than among females in England and Wales and in Italy. Over time, the contribution of the educational expansion to trends in e₃₀ and ed₃₀ increased. Mortality changes among the low-educated contributed the most to increases in e₃₀ but counterbalanced selected declines in ed₃₀. Educational expansion thus proved to be an important driver of both longer and more equal lifespans. Our finding suggests that educational expansion will also likely influence future mortality progress.
