The world is becoming more violent - here are the most and least peaceful countries

According to an annual report from the Institute for Economics and Peace (IEP), Botswana, Kuwait, Morocco, Kazakstan, Vietnam, Angola, and Burkina Faso all have one surprising thing in common: they are more peaceful than the US.

The Global Peace Index from the Institute for Economics and Peace compiles yearly rankings of 'peacefulness' in 162 nations worldwide based on 23 different types of data.?

The Institute for Economics and Peace attempts to answer a simple question: Is the world getting more or less peaceful?

The report also includes an analysis of the economic impact of containing and dealing with the consequences of global violence. Last year violence containment was estimated to be $14.3 trillion which is approximately 13.4% of the world's gross domestic product.
