It is even worse than that as Martinique is a “territory governed by France” in much the same way that Hawai’i is a territory governed by the USA.
Martinique is a region and department of France—and administrative subdivision of the same type as those in the French mainland, differing only in that the the top two levels of subdivision (region and department) are coextensive rather than nested in Martinique and the other overseas region/departments.
