Boundary: De facto, as drawn by Natural Earth.
Area: Measured on the WGS84 ellipsoid from the full-detail outline, shown rounded. The region’s whole area is counted, every island included.
Official figures: Area, population and capital from Wikidata (CC0), fetched 2026-11-12
Population: Wikidata, 2022. France’s units share the 2022 figures where Wikidata has them; the year is shown wherever the figure is.
Matching: Countries come from Natural Earth’s country file. Places whose status is contested and dependencies are never used as automatic matches. A region under 2,500 km² is matched against the small countries and island nations.
