An urban refugee is a refugee who decided or was obliged to settle in an urban area rather than in a refugee camp in the country or territory where the person fled to. More than 60% of the world's refugee population and 80% of internally displaced persons (IDP) under UNHCR mandate live in urban environments. In 2009, their number was around 5.5 million people. "Urban refugee" is not a recognized legal term in the 1951 Convention relating to the Status of Refugees. However, the UNHCR has adopted a 'Policy on Refugee Protection and Solutions in Urban Areas' in 2009.
