Sources and method
- Outlines
- Natural Earth, 1:10m Admin 0 - Countries, public domain
- Boundary
- De facto, as drawn by Natural Earth. Main territory: the largest landmass and every part within 1,000 km of it.
- Area
- Measured on the WGS84 ellipsoid from the full-detail outlines, shown rounded. Comparisons use main-territory area.
- Drawing
- Each outline is projected with an equal-area projection centred on its own centroid, so areas stay true and the two can be laid over each other.
