The government required IDPs to register their place of residence in an attempt to better target the limited and largely inadequate national and international assistance due to the Armenian advocated and US imposed restrictions on humanitarian aid to Azerbaijan. Many IDPs were from rural areas and found it difficult to integrate into the urban labor market. Many international humanitarian agencies reduced or ceased assistance for IDPs citing increasing oil revenues of the country. The infant mortality among displaced Azerbaijani children is 3–4 times higher than in the rest of the population. The rate of stillbirth was 88.2 per 1,000 births among the internally displaced people. The majority of the displaced have lived in difficult conditions for more than 13 years.
