Sources and method
- Outlines
- Natural Earth, 1:10m Admin 1 - States, Provinces, public domain for the region; Natural Earth, 1:10m Admin 0 - Countries, public domain
- Boundary
- De facto, as drawn by Natural Earth. A region is drawn whole, every island included; a country is its main territory.
- Area
- Measured on the WGS84 ellipsoid from the full-detail outlines, shown rounded.
- 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.
