Countries with the worst life expectancy
From the discovery of penicillin in 1928 to the first use of an artificial heart in 1969, the past 100 years have been filled with incredible advancements in the field of medicine and overall quality of life for billions of people all around the world. As a result, Americans (and many other nations) are living longer - the average life expectancy has more than doubled in the past 100 years, an astounding number for such a short period of time.
Unfortunately, not all modern advancements - in medicine, technology, and elsewhere - have been extended to all global citizens, and the World Health Organization's most recent 2017 report tells a harrowing story of how life expectancy changes from country to country.
In 2014, life expectancy in the U.S. hit an all time high, at 78 years and 9 ½ months. As WHO's report shows, many countries have average life expectancies more than 20 years shorter, a fact that dozens of NGO's across the globe are aiming to help with. To spread more awareness of how stark a contrast there is across the globe, Stacker analyzed the World Health Organization's 2017 report, which compiles life expectancy data and data on health-related sustainable development goals. All data used is from 2015, except for road traffic mortality rate (from 2013), pollution mortality rate (from 2012), and % of government expenditures going to global health (from 2014).
Read on to see the 50 countries with the lowest average life expectancy across the globe.
