The number of people around the world who have been forced to flee home due to war or some other life-threatening crisis hit a 19-year high in 2012, according to a new report by the United Nations' refugee office. In all, 45.2 million people have been displaced by conflict and crisis. "This means one in each 4.1 seconds," says Antonio Guterres, the U.N. high commissioner for refugees. "So each time you blink, another person is forced to flee." Here, a look at the extent of the global refugee epidemic, by the numbers:
