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.
