The 19 poorest, unhappiest, unhealthiest, and most dangerous nations in the world

The Legatum Institute, a London based research institute released its 10th annual global Prosperity Index, a huge survey that ranks the most prosperous countries in the world, on Thursday.

Prosperity may mostly be used to talk about money, but the Legatum Institute thinks there is more to it than that.

The organisation compared 104 separate variables to come up with its list. These variables include traditional indicators like per-capita gross domestic product and the number of people in full-time work, but also more interesting areas such as social tolerance and how good a nation's internet is.

The variables are then split into nine subindexes: economic quality, business environment, governance, education, health, safety and security, personal freedom, social capital, and natural environment.

We've already shown you the 25 countries that the Prosperity Index rated as the most prosperous, or in other words, the happiest, wealthiest, and most crime-free places on earth. Now it's time to look at the countries at the other end of the list.

Many of the countries that feature toward the bottom end of the index have been hit hard by wars and outbreaks of disease. They are generally lacking in strong economies, governments, and education systems.

We've taken the bottom 19 countries from the Legatum Institute's index and ranked them in reverse order, where No. 1 represents the "least prosperous" country.

The index looked at the 149 countries in the world that have the most available data. As a result, it should be noted that certain prominent countries, including Syria and North Korea, do not feature because of a lack of available data.
