The United Nations has compiled some infographics based on official data sources on migrants and refugees worldwide.
According to the data, the number of refugees and migrants has significantly increased in the past 15 years, along with the number of people losing their lives along migratory routes (10,400 in 2014 and 2015 only). Most refugees live in Sub-Saharian Africa and Middle Eastern countries, with Turkey alone hosting more than 2 million beneficiaries of international protection.
Migrants make a significant contribution to economic growth both in their country of origin and in their country of residence; it is estimated that in 2015 alone, migrants produced about 432$ billion in remittances.
