Anguilla, puerto rico, and are among the few caribbean territories that are not independent countries.

That would be Martinique.
Surprisingly neither Anguilla, Puerto Rico nor Martinique are independent states even today. Martinique is a French territory located in the Caribbean Sea. Puerto Rico is of the United States even though unincorporated part and its citizens are citizens of the US and can move freely between the island and the US mainland. Anguilla is part of the United Kingdom.

Americans often speak of their country as one of several large regions.  these regions are cultural units rather than governmental units --  formed by history and geography and shaped by the economics, literature and folkways that all the parts of a region share. what makes one region different from another? a region's multicultural heritage as well as distinct demographic characteristics like age and occupation make regions different and special. within several regions, language is used differently and there are strong dialects. there are also differences in outlook and attitude based on geography.
