- Settlement Point Coordinate Source Data:
- AFCities, Getty, NIMA, Times Atlas of the World, 1, World Gazetteer
- Urban Criteria for Settlements (UN):
- Agglomerations of 5,000 inhabitants or more where 75 per cent of the economic activity is non-agricultural.
- Administrative Population Edits and Notes:
- ? To match the 1991 population with the boundary data, the following adjancement were made. First the populations listed separately for urban areas were added to the corresponding districts. Next it was determined which district populations needed to be split into which units in the GIS coverage:
? Central Serowe/Palapye into Serowe and Palapye;
? Tuli population was estimated as a share of the Palapye;
? Machaneng and Bobonong populations;
? Kweneng into Kweneng South and North;
? Ngwaketse into Ngwaketse North Central and South;
The shares were determined as follows: First the population of urban places in the districts were assigned to the correct districts (usually the coordinates were obtained from the Times Atlas and the district into which the place falls was determined using the GIS coverage). Next the residual population was split weighted by area; where this would make little sense due to the nature of the districts'' terrain, uniform shares were used.
? 2000 population for Serowe and Palapye districts were created by splitting the 2000 Serowe/Palapye figure and distributing it according to the 1991proportions.
? For the 2000 population, Ngwaketse South and Ngwaketse Central polygons . The 2000 data for Southern district was then split in proportion to the 1991 population distribution, with South and Central assumed to be one data entry, and assigned to Ngwaketse North and South. Then, 2000 data for Ngwaketse West was added to Ngwaketse North.
? 1991 and 2000 population of data for Delta district was added to Ngamiland East district.
? 1991 and 2000 population for Francistown and North East was added and assigned to Masungu district.
? 1991 and 2000 data for Central Boteti was assigned to Machaneng
? 1991 and 2000 population for Orapa was added to Lethlakane
? 1991 and 2000 population for Central Bobonong and Selibe Phikwe was added and assigned to Bobonong district.
? 2000 data for Sowa district added to Tutuma and CKGR district added to Ghanzi.
? 2000 data for Kgalagadi South was split and distributed to two districts -- Tshabong and Gemsbok -- in proportion to their 1991 estimates.
? 2000 data for Kgalagadi North was assigned to Hukunsti district.
? 1991 and 2000 population of Lobatse added to South East district population.
A 5% growth rate was applied to select units.
- Administrative Spatial Edits and Notes:
- (1) Tuli district was merged with 3 districts: Palapye, Machaneng, and Bobonong. The population 1990 data for Tuli was split equally 3 ways and added to each district''s population 1990 total. P00 data for Tuli region is assumed to be part of those three districts.
(2) 2000 data for Kgalagadi South was split and distributed to 2 districts, Tshabong and Gemsbok, in proportion to their population 1990 estimates. 2000 data for Kgalagadi North was assigned to Hukunsti district.
(3) The population 2000 figure for South East district was created by adding 2000 data for South East and Lobatse
(4) The population 2000 data for Serowe and Palapye districts were created by splitting the 2000 Serowe/Palapye figure and distributing it according to the population 1990 proportions.
(5) Ngwaketse South and Ngwaketse Central were merged, and the population 1990 figures for each one (exact same number) were assumed to be a repeat, so only one set of data was assigned to the merged polygon (Ngwaketse South). 2000 data for Southern district was then split in proportion to the population 1990 data, with South and Central assumed to be one data entry, and assigned to Ngwaketse North and South. Then, 2000 data for Ngwaketse West was added to Ngwaketse North.
(6) 2000 data for Delta district was added to Ngamiland East district.
(7) 2000 data for Francistown and North East was added and assigned to Masungu district.
(8) 2000 data for Central Boteti was assigned to Machaneng
(9) 2000 data for Orapa was assigned to Lethlakane
(10) Kweneng South district was renamed Kweneng West, and the population 2000 total was found by adding Kweneng West and Jwaneng
(11) Kweneng North district was renamed Kweneng East.
(12) 2000 data for Central Bobonong and Selibe Phikwe was added and assigned to Bobonong district.
(13) "Central" was deleted from any related district names
(14) 2000 data for Sowa district and CKGR district was not assigned to any districts due to lack of information on location (about 3,500 people).
