Both maps below show Saint Barthélemy highlighted. At 18° Mercator inflates Saint Barthélemy by only about 10%, so the two maps largely agree on it. Watch what the old map does to Bahamas beside it. That contrast is why the new world map matters.
At 18°, Saint Barthélemy sits in the band the old map drew almost honestly. It is one of the regions Mercator quietly under-represented, and that is exactly what the new Equal Earth map restores.
