The global economic crisis and reverberations from the Arab Spring color the latest edition of Aon Risk Solutions' Terrorism & Political Violence Map. The 2012 map shows 37 countries downgraded to reflect a growing level of risk, including three countries—Maldives, Senegal and Papua New Guinea—that underwent double downgrades. Meanwhile, six countries were upgraded to reflect reduced risks.

In 2011, the map, which Aon produces in collaboration with Risk Advisory Group, showed 19 downgrades and 11 upgrades.

Neil Henderson, head of terrorism for Aon Risk Solutions' crisis management practice, pictured at right, says that while the focus of the map in the wake of 9/11 was mostly on terrorism, that has shifted over the last couple of years as more and more countries experience political unrest and riots.
