Sources and method

Outlines: Natural Earth, 1:10m Admin 1 - States, Provinces, public domain. The outline of Brittany is the departments Natural Earth draws there, joined along their shared borders. The outline of Sicily (Italy) is the provinces Natural Earth draws there, joined along their shared borders.
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.
