Turkey has long been affected by migration both as a country of emigration and transit for irregular migrants. In recent decades, it has increasingly become a destination for economic migrants and refugees from Eastern Europe, Iran, Afghanistan and Syria. As of 2010, over 1.4 million migrants resided in Turkey, most originating from Bulgaria, Germany, Greece and other neighboring countries. Turkey also hosts over 3.6 million Syrian refugees, the largest population of refugees from Syria globally.
