I think that St. Pierre et Miquelon are not a Departement Outre Mer (DOM) (an overseas department, like Hawaii or Alaska) but a Territoire Outre Mer (TOM)(an overseas territory, like Guam or Puerto Rico).
There are 4 DOM: Guiane Francaise (French Guiana) in South America (this is where the European Space Agency rockets are launched into space), Guadeloupe, Martinique and La Reunion in the Indian Ocean.
There are many TOM: St. Pierre et Michelon, la Nouvelle Caldeonie, Mayotte, Wallis & Futuna, Polynesie (Tahiti).
