Life Expectancy Growth 2015-2050

Map No.


The highest increase in life expectancy between 1950 and 2015 was recorded in Central African Republic (∽24 years), followed by Lesotho (∽23 years),  Equatorial Guinea (∽22 years), Nigeria (∽21 years) and Swaziland (∽20 years). Cameroon, Mozambique, Guinea, Chad and the Democratic Republic of Congo complete the all African top 10. Countries with an already large life expectancy therefore become smaller while those countries with large populations and major improvements are the largest in these images. In absolute years (life expectancy growth x population) India is leading the table with more than 10 billion extra life years, followed by China, Nigeria, Democratic Republic of Congo and the USA.
Overall the 2018 Human Development Report (HDR) reported 11 countries with a life expectancy of less than 60 years. All of them are in Africa. The Central African Republic, Sierra Leone and Chad are among those with a life expectancy of below 55 years.

Technical Notes

Territory size shows the proportion of the extra years of life lived by their population through increases in life expectancy between 2015 and 2050.

Data sources

This map uses data by the United Nations, Department of Economic and Social Affairs, Population Division (2017). World Population Prospects: The 2017 Revision, DVD Edition (last accessed January 2019).

We aim to map as complete data as possible and therefore estimate data for missing values. In some cases, missing data for very small territories is not used in the cartogram and that area is therefore omitted in the map. Further notes on the data, as well as all modifications to the original data source are noted in our data sheets.
