List of countries by life expectancy – Wikipedia

This is a collection of lists of countries by average life expectancy at birth.

Life expectancy equals the average number of years a person born in a given country is expected to live if mortality rates at each age were to remain steady in the future. The life expectancy is shown separately for males and females, as well as a combined figure. Several non-sovereign entities are also included in this list too.

The figures reflect the quality of healthcare in the countries listed as well as other factors including ongoing wars, obesity, and HIV infections.[citation needed]

Worldwide, the average life expectancy at birth was 71.0 years (68 years and 6 months for males and 73 years and 6 months for females) over the period 20102013 according to United Nations World Population Prospects 2012 Revision,[3] or 70.7 years (68.2 years for males and 73.2 years for females) for 2009 according to The World Factbook.[4] According to the World Health Organization (WHO), women on average live longer than men in all countries, with the exception of Tonga.

The countries with the lowest overall life expectancies per the WHO are Sierra Leone, the Central African Republic, the Democratic Republic of the Congo, Guinea-Bissau, Lesotho, Somalia, Swaziland, Angola, Chad, Mali, Burundi, Cameroon, and Mozambique. Of those countries, only Lesotho, Swaziland, and Mozambique in 2011 were suffering from an HIV prevalence rate of greater than 10 percent in the 1549 age group.[5]

Comparing life expectancies from birth across countries can be problematic. There are differing definitions of live birth vs stillbirth even among more developed countries and less developed countries often have poor reporting.[6]

On July 2015, the Population Division of the United Nations Department of Economic and Social Affairs (UN DESA), released World Population Prospects, The 2015 Revision.[3] The following table shows the life expectancy at birth for the period 2010 to 2015.

The Global Burden of Disease 2010 study published updated figures in 2012,[10] including recalculations of life expectancies[11] which differ substantially in places from the UN estimates for 2010 (reasons for this are discussed in the freely available appendix to the paper, pages 2527, currently not available). Although no estimate is given for the sexes combined, for the first time life expectancy estimates have included uncertainty intervals.

The US CIA published the following life expectancy data in its annual world factbook 2012.[1]

Figures are from the CIA World Factbook 2009[1] and from the 2010 revision of the United Nations World Population Prospects report, for 20052010,[3] (data viewable at http://esa.un.org/wpp/Sorting-Tables/tab-sorting_mortality.htm, with equivalent spreadsheets here, here, and here).

Only countries/territories with a population of 100,000 or more in 2010 are included in the United Nations list. WHO database 2013 http://www.who.int/gho/publications/world_health_statistics/EN_WHS2013_Full.pdf
