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.
