Catching Up on Mortality, Falling Behind on Disability: A Dynamic Decomposition of the Health‑Adjusted Life Expectancy Gap between Higher‑Income and Lower‑Income Countries
Background: Global health inequalities are conventionally assessed through the mortality gap, yet the joint contribution of mortality and disability to health‑adjusted life expectancy (HALE) gap and their dynamic evolution remain poorly understood. We aim to decompose the HALE gap between higher‑income and lower‑income countries into mortality and disability drivers, separate long‑term trends from transient fluctuations, and reveal heterogeneity within the low‑income group. Methods: Using data from the Global Burde …
