Administrative Population Edits and Notes:
The population figures of several administrative units were aggregated in order to match boundaries of the shapefile (population units: 55 and shapefile units: 25). The maps on the Web site were used as a guide for this process. A 5% growth rate cap was applied to select units.
Administrative Spatial Edits and Notes:
The following spatial edits were made: (1) New spatial data clipped to DCW (2) In the ''Mwanza'' region, all level 2 units were dissolved/amalgamated to level 1 because it was not possible to identify how the new units were created in this area (3) The most recent boundaries contained 95 units, but six of these were merged into a single unit in order to make the population data for two time periods compatible.
