| According to the source, this list is based on the following criteria: air pollution, access to drinking water, sanitation, infant mortality rates, prevalence of tuberculosis, density of physicians par 1000 people, undernourishment rates, and healthy life expectancy.
The source also states that only 138 countries were included in the analysis due to incomplete data.
I was somewhat surprised by this list-- I expected to see Japan on it, and I most definitely didn't expect to see the USA. |
