This study investigated the macroeconomic determinants of life expectancy in Nigeria. Variables such as income per capita, unemployment, inflation, income inequality, health investment; health system measured by physician per 1,000 population and the environment measured by the carbon dioxide emission index were assessed. Time series data on these variables from 1980-2015 were estimated using the Ordinary Least Squares technique. Of the macroeconomic variables included in the model, income inequality was the largest predictor of life expectancy. The other macroeconomic variables significant in explaining life expectancy are income per capita and government capital expenditure on health. Also, carbon dioxide emission and physician per 1,000 population were found to be significant in explaining life expectancy in Nigeria. The study underscores the need for income redistribution, higher income levels in Nigeria and the employment of skilled health personnel to man the health system a top priority in order to improve life expectancy.
