For those who've been paying attention, it's clear that the upheaval we've seen in Egypt and elsewhere stems from a globally contagious shift in the social mood. Given that, most people would probably find it helpful (or even essential) to know which country or countries might be next. Thanks to The Economist, we now have a reference source, "The Shoe Thrower's Index," that attempts to answer that question.
An index of unrest in the Arab world
The chart below is the result of ascribing a weighting of 35% for the share of the population that is under 25; 15% for the number of years the government has been in power; 15% for both corruption and lack of democracy as measured by existing indices; 10% for GDP per person; 5% for an index of censorship and 5% for the absolute number of people younger than 25. Jordan comes out surprisingly low on the chart, which suggests the weighting might need to be tweaked.
