On September 19, 2016 the United Nations General Assembly adopted a set of commitments during its first ever summit on large movements of refugees and migrants to enhance the protection of refugees and migrants. These commitments are known as the New York Declaration for Refugees and Migrants (NY Declaration). The NY Declaration reaffirms the importance of the international protection regime and represents a commitment by Member States to strengthen and enhance mechanisms to protect people on the move. On 4 December 2000, the General Assembly, taking into account the large and increasing number of migrants in the world, proclaimed 18 December International Migrants Day (A/RES/55/93). On that day, in 1990, the Assembly adopted the International Convention on the Protection of the Rights of All Migrant Workers and Members of Their Families (A/RES/45/158).
The total number of international migrants has increased from an estimated 175 million in 2000 to 244 million persons in 2015. Nearly two thirds of all international migrants live in Europe (76 million) or Asia (75 million). Migration is now more widely distributed across more countries. Today the top 10 countries of destination receive a smaller share of all migrants than in 2000.
