Overview
An internally displaced person (IDP) is someone who is forced to leave their home but who remains within their country's borders. They are often referred to as refugees, although they do not fall within the legal definitions of a refugee.
At the end of 2014, it was estimated there were 38.2 million IDPs worldwide, the highest level since 1989, the first year for which global statistics on IDPs are available. the countries with the largest IDP populations were Ukraine (8 million), Syria (7.6 million), Ethiopia (5.5 million), the Democratic Republic of the Congo (5.2 million), Colombia (4.9 million), Yemen (4.3 million), Afghanistan (3.8 million), Iraq (3.6 million), Sudan (2.2 million), South Sudan (1.9 million), Pakistan (1.4 million), Nigeria (1.2 million) and Somalia (1.1 million).
The United Nations and the UNHCR support monitoring and analysis of worldwide IDPs through the Geneva-based Internal Displacement Monitoring Centre.
Definition
Whereas 'refugee' has an authoritative definition under the 1951 Refugee Convention, there is no universal legal definition of internally displaced persons (IDP); only a regional treaty for African countries (see Kampala Convention). However, a United Nations report, Guiding Principles on Internal Displacement uses the definition of:
persons or groups of persons who have been forced or obliged to flee or to leave their homes or places of habitual residence, in particular as a result of or in order to avoid the effects of armed conflict, situations of generalized violence, violations of human rights or natural or human-made disasters, and who have not crossed an internationally recognized State border.
