Administrative Population Source Data:
(1) Central Bureau of Statistics (1993), Population census of Sudan 1993, Census Office, Khartoum. Incomplete due to partial enumeration in Southern Sudan. Boundaries seemed to have changed somewhat between ''83 and ''93, but no map was available. (2) Population Studies Center (1983), Population of Sudan and its regions, Project Document 1, 1983 census: Total populations by region, province and district, University of Gezira jointly with Department of Statistics, Census Office.

UNEP/GRID-WRI-NCGIA Africa Population Database:
Settlement Point Population Source Data:
AFCities, Data provided by Uwe Deichman at the World Bank; City Population,; Fourth Population Census of Sudan 1993, UN Statistical Library; World Gazetteer,
Settlement Point Coordinate Source Data:
AFCities, NIMA, UNSD, World Gazetteer
Urban Criteria for Settlements (UN):
Localities of administrative or com-mercial importance or with a population of 5,000 inhabitants or more.
Administrative Population Edits and Notes:
(1) Population figures for Kapoeta were reallocated to the remainder of Kapoeta, without proportional reduction in population, because it was considered unlikely that either Northern or Southern Sudan conducted a census in this region, due to lack of access and presumed cession to Kenya, respectively. (2) The population values for 1990 are based on the intercensal 1983-1993 growth rate for the districts (administrative level 3), where available. For the units where district population was not enumerated, a region level growth rate was used to extrapolate the population to 1990. (3) In order to further extrapolate the population to target years, growth rates derived from United Nations national level estimates and projections were employed.
Administrative Spatial Edits and Notes:
Boundaries changed significantly between the three censuses, so data had to be aggregated or split to match the available boundary data set. The boundaries match the 1983 census although some of the unit names are different in the coverage and the census publications. The Ilemi Triangle , in Kapoeta [admin3 unit] belongs to Sudan by treaty but is administered by Kenya. According to a recent paper by Collins, SPLM/SPLA, the rebel group that controls Southern Sudan, probably quietly ceded the territory to Kenya.
