Who shares a language with Trinidad & Tobago
Shared-language index of every country with Trinidad & Tobago; the legend is the key.
Small territories are not drawn at this scale.
Nearest
The countries whose people can talk most easily with Trinidad & Tobago's.
How this is measured
Shared language is the common spoken language index from the USITC DICL: the sum over languages of the share of people in Trinidad & Tobago who speak it times the share in the other country, native or acquired. It is not a probability and can exceed 1, because the shares overlap. Proximity measures how close different native languages sit on the language tree, so it is low for same-language pairs and highest for related-but-different languages. Countries under 1 million residents are left out of both boards.
