Abstract: -Life expectancy has risen substantially across Sub-Saharan African (SSA), but national trajectories have diverged. Malawi represents a striking case of transformation, moving from one of the region’s lowest ranked countries in 1950 to among its leaders in 2023 despite persistent economic stagnation. We examine how age specific mortality changes contributed to Malawi’s exceptional gains in life expectancy and compares its mortality transition with those of other SSA countries. We use age and sex specific mortality data from the 2024 United Nations World Population Prospects for 15 SSA countries between 1950 and 2023. Countries were selected to represent the highest, average, and lowest performing groups in life expectancy at birth in 1950. We analyze trends, decompose changes using the Arriaga method, and estimate potential future gains from eliminating mortality at specific ages. Results show that Malawi recorded the largest increase in life expectancy, gaining 36.2 years for females and 33.2 years for males. Its mortality decline followed a broadly similar age pattern to the region but with exceptional intensity: between 1950 and 1980, two thirds of gains came from childhood mortality reductions, while after 2000, adult survival improvements contributed nearly half. Malawi’s resilience during the HIV/AIDS crisis and rapid post 2000 recovery highlight the combined influence of expanded female education, large scale donor investment, and community-based health programs. Our findings provide the first long term age specific decomposition of Malawi’s life expectancy transformation in comparative SSA context, highlighting the changing age structure of mortality reduction in the region.
