This is not the worst countries. This is like below average but not the worst.
The worst countries to live in are mostly African countries that war and famines are very common like Sierra Leone, Mozambique, Congo, Chad and Sudan.

Since when did my country Mozambique descend to the level of Sierra Leone?
In my country we live very well, we have democracy, we do not have war
As long as you do not live in the country, you can not say how good and bad it is. In every country there is at least one city completely unfit for living.
