The International Organization for Migration estimates that the number of global migrants increased from 150 million people in 2000 to 214 million in 2010. The organization also reported that the number of refugees worldwide was 15.4 million in 2010, while the number of internally displaced persons increased to 27.5 million in 2010 from 21 million in 2000. Of the total migrant population, about 49 percent were women. About 72.1 million international migrants resided in Europe, while 19.3 million migrants were recorded in Africa. The figures reflect the trend of migrants moving from less developed regions to more developed regions that provide more economic opportunities.
