Life Expectancy
Life expectancy for all the different countries in the world ranges from a low of only 52.2 years (in Sierra Leone) to a high of 84.7 years
(in Hong Kong). Life expectancies are clustered at the high end, with about half of all the countries having a life expectancy between
about 74 and the maximum of 84.7. A few countries, such as Sierra Leone, have a very low life expectancy. The full dataset is in
AllCountries.
