Expulsion of Asian noncitizens was decreed by the Amin government in 1972; almost all the nation's 74,000 Asians, both citizens and noncitizens, emigrated during the Amin regime. In 1982, the government enacted the Expropriated Properties Bill, which provided for the restoration of property to Asians expelled under Amin. About 6,000 Asians had returned by 1983.
After the fall of the Amin regime, as many as 240,000 people from Amin's West Nile district may have fled to the former Zaire and the Sudan. Many of them returned to Uganda in 1983; government campaigns against guerrillas, however, displaced thousands more, and at the end of 1986 there were an estimated 170,000 Ugandan refugees in Sudan and 23,000 in Zaire. The refugee population in Zaire remained steady, but the number in the Sudan had dropped to 3,800 by the end of 1992.
As of 2000, Uganda had 529,000 migrants including 236,000 refugees. According to the UNHCR, these refugees are primarily from Sudan, Rwanda, the DROC, and other neighboring African nations. The net migration rate that year was -0.6 migrants per 1,000 population. The government views the migration levels as satisfactory.
