NPR: People Are Living Longer in Places You Wouldn't Expect
By Emily Sohn
Where can people expect to live the longest?
The answer to that question is usually pretty predictable and often dependent on wealth: People generally live longer in richer countries. Like Japan and Switzerland, where average life expectancies exceed 83 years.
In lower income countries, expected years of life are often far shorter — hovering below 55 in a number of sub-Saharan countries, including Chad, Mozambique and Sierra Leone.
