An internally displaced person (IDP) is someone who is forced to flee his or her home but who remains within his or her country's borders. They are often referred to as refugees, although they do not fall within the current legal definition 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 Syria (7.6 million), Colombia (6 million), Iraq (3.6 million), the Democratic Republic of the Congo (2.8 million), Sudan (2.2 million), South Sudan (1.6 million), Pakistan (1.4 million), Nigeria (1.2 million) and Somalia (1.1 million).
