International Organization on Migration (IOM)
IOM works to help ensure the orderly and humane management of migration, to promote international cooperation on migration issues, to assist in the search for practical solutions to migration problems and to provide humanitarian assistance to migrants in need, including refugees and internally displaced people. 

UN High Commission for Refugees (UNHCR)
The UNHCR is mandated to lead and co-ordinate international action to protect refugees and resolve refugee problems worldwide. Its primary purpose is to safeguard the rights and well-being of refugees.

• Publications - UNHCR publishes a wide range of materials ranging from basic documents to refugee and international law reports and research and evaluation papers. The agency's worldwide operations are covered in the two flagship annual publications - The Global Appeal and Global Report.

• Refugee Data Finder - This page provides data, trends, an interactive data visualization platform and statistical reports on the people of concern to UNHCR: refugees, asylum seekers, returned refugees, internally displaced and stateless people around the world.  Toward the bottom of the Data & Resources page you will find links to several reports/data resources including Global Trends, Global Report, Operational Data Portal, Global Focus Portal, Resettlement Data Finder, and Refugee Statistics.

  • "The UNHCR mandate covers all refugees, except some 4.9 million Palestinian refugees residing in areas of operation of the United Nations Relief and Works Agency for Palestinian Refugees in the Near East (UNRWA). These Palestinian refugees are not included in UNHCR's statistics. However, the Palestinian refugees living outside the UNRWA areas of operation fall under the responsibility of UNHCR and are thus included in UNHCR statistics."  [2013, General Notes on UNHCR Statistics]
