The second-level geography for Ghana is said to be harmonized at the district-level for the period 2000-2010, i.e. the two population censuses.
However, in the respective datasets, only the variable geo2_gh2000, label “Ghana, District 2000 [Level 2, GIS]” contains the correct number of districts in the year 2000, which is 110. The variable geo2_gh, label “Ghana, District 2000 - 2010 [Level 2; consistent boundaries, GIS” only contains 102 districts. Unfortunately for my research, also the downloadable boundary map of Ghana shows only the incorrect 102 districts.
Is a correction of the map already in the works? I have recently worked on tracking the changes in Ghanaian districts from 1988 to 2012 and could potentially provide some help.
