From the introduction to the GPI:
“The Global Peace Index is composed of 24 indicators, ranging from a nation’s level of military expenditure to its relations with neighbouring countries and the level of respect for human rights. The index has been tested against a range of potential “drivers” or determinants of peace—including levels of democracy and transparency, education and material wellbeing.”
