List of countries by life expectancy

This is a list of countries by life expectancy at birth, the average number of years to be lived by a group of people born in the same year, if mortality at each age remains constant in the future. The entry includes total population as well as the male and female components. Several non-sovereign entities are also included in this list. Figures are from the 2006 revision of the United Nations World Population Prospects report, for the period 2005-2010. Only countries/territories with a population of 100,000 or more in 2007 are included.

The life expectancy (both sexes, at birth) ranges from 82.6 years in Japan to 39.2 years in Swaziland. Many of the countries with the lowest life expectancies, namely Swaziland, Botswana, Lesotho, Zimbabwe, Zambia, Mozambique, Malawi, South Africa, Central African Republic, Namibia, and Guinea-Bissau, are suffering from very high rates of HIV/AIDS infection, with adult prevalence rates ranging from 10 to 38 percent. Also note that in countries with high infant mortality rates, the life expectancy at birth will be lower and may not reflect the life expectancy a person that has survived his/her first year of life would have.
