- The United Kingdom
Also ranking at 2.72, the United Kingdom has a good Global Peace Index on the basis of low violent crime, high political stability, and low political violence. The United Kingdom is a developed country and has the world’s fifth-largest economy by nominal GDP and ninth-largest economy by purchasing power parity. UK was the world’s first industrialised country and the world’s foremost power during the 19th and early 20th centuries. It gets dinged a bit because of a high level of militarization and threats of terrorism. That’s also why the State Department assigns it to level two.
