Administrative Population Edits and Notes:
Kingmen County and Lienkiang County sum to form Kingman-Matsu Area.
Administrative Spatial Edits and Notes:
1990 and 1995 population estimates were added to GPW3 units from GPW2 as follows: 1) GPW2 polygons projected to match GPW3 coordinate system with slight adjustment in false northing to compensate for misalignment 2) Converted projected GPW2 polygons to centroids 3) Visually inspected centroids to ensure placement within appropriate GPW3 polygon (verified by comparing to administrative unit names) and moved when necessary 4) Where disaggregation occurred, centroids were copied and pasted to corresponding empty polygons. 5) Performed spatial join in ArcMap to assign GPW2 attributes to the new polygons and assigned the sum of each population attribute if there were multiple centroids within each polygon 6) Inspected data to ensure no data loss 7) Data were converted to lat/long coordinates
