The number of migrating migrants between 2010 and 2015 (36.5 million) is more than 8 million fewer than in the previous five-year period (45 million). The global migration rate reached an historic peak between 1990 and 1995, a time when the Iron Curtain had fallen, Afghanistan had descended into civil war and there was genocide in Rwanda. The 0.5 percent figure for the last five years is the smallest value since 1960. . . . What distinguishes a refugee from a migrant? One of them migrates voluntarily, while the other is forced to do so. However, the UN migration figures toss both categories into the same pot.
