Two indices we can refer to as we calculate State Legitimacy are the Foreign Policy Failed State Index, and the Interbrand Global Brand Index. I’ve referred already to the Foreign Policy Index here, and I thought I’d mentioned the Interbrand Index here, but I can’t quite put my finger on the link.
The failed state index can be inverted, as we said, to indicate the extent to which states have succeeded, which is interesting. The categories too are interesting – demographic pressures, refugees / IDPs, group grievances, human flight, uneven development, economic decline, delegitimization of the state, public services, human rights, security apparatus, factionalized elites, and external intervention. In truth it sounds like the table of contents for a rather interesting book! The methodology for the index, which is run in conjunction with the Fund for Peace, outlines how each metric is calculated, though it is most certainly an inexact science.
