Administrative Population Edits and Notes:
Population data were extrapolated to target years of 1990, 1995 and 2000 using national level growth rates between 1994 and 2004 censuses.
Administrative Spatial Edits and Notes:
The boundaries were rubber-sheeted in the Northwestern part of the country in order to better match the DCW coastlines.
