Reading the news, it’s easy to get the sense that the world is at war: strife in Afghanistan, chaos in Iraq, genocide in Darfur, upheaval in Lebanon, and a variety of insurgencies and border squabbles around the globe. Reading the news, it’s also easy to get the sense that the world is in the midst of a golden age of peaceful prosperity. Each year, tens of millions of Indians and Chinese join the middle class. Latin America and South America, previously dominated by authoritarian regimes and civil wars, are now generally democratic and enjoying steady growth.
So, which is it? Is the world more peaceful or more warlike? Since Americans are doing the lion’s share of the fighting and military policing, it’s difficult for us to answer the question objectively. Fortunately, there is an unbiased global economic indicator that sheds some light on the question: the Guns-to-Caviar Index.
