The Nagorno-Karabakh conflict has resulted in the displacement of 597,000 Azerbaijanis (this figure includes 230,000 children born to internally displaced persons (IDPs) and 54,000 who have returned) including Artsakh, and 220,000 Azeris, 18,000 Kurds and 3,500 Russians fled from Armenia to Azerbaijan from 1988 to 1989. The Azerbaijani government has estimated that 63% of IDPs lived below the poverty line as compared to 49% of the total population. About 154,000 lived in the capital, Baku. According to the International Organization for Migration, 40,000 IDPs lived in camps, 60,000 in dugout shelters, and 20,000 in railway cars. Forty-thousand IDPs lived in EU-funded settlements and UNHCR provided housing for another 40,000. Another 5,000 IDPs lived in abandoned or rapidly deteriorating schools. Others lived in trains, on roadsides in half-constructed buildings, or in public buildings such as tourist and health facilities. Tens of thousands lived in seven tent camps where poor water supply and sanitation caused gastrointestinal infections, tuberculosis, and malaria.
