4. Who Assists Refugees? The primary caretaker of refugees worldwide is the United Nations High Commissioner for Refugees (UNHCR), which operates in 120 countries and assists 25 million people. There is no formal assistance for internally displaced persons. The UN Special Representative for IDPs, Francis Deng, lobbies governments worldwide to raise awareness of the plight of IDPs. Dozens of relief organizations, non-governmental organizations, and religious groups provide assistance to refugees.
