The Human Development Index for Sierra Leone published by the United Nations is a composite measure including life expectancy, educational attainment, and income level. It aims to measure not only incomes but life quality as well.

Four indicators are used to calculate the index: life expectancy at birth, mean years of schooling, expected years of schooling, and gross national income per capita.
