No — the Bermuda Triangle has zero permanent population. It is not a country, territory, or inhabited region. Rather, it’s a loosely defined area in the western North Atlantic Ocean, roughly bounded by Miami (Florida), Bermuda, and Puerto Rico.
The "Bermuda Triangle" is a popular culture term, not an official geographic or political zone. It covers a heavily trafficked maritime corridor where ships and aircraft routinely pass — including commercial vessels, cruise liners, and military craft.
Only transient mariners, aviators, and researchers — no residents, cities, or governments. The islands at its corners (Bermuda, Puerto Rico, Florida Keys) are populated, but the triangle itself is just open ocean.
So while it captures imaginations, the Bermuda Triangle is geographically ordinary — just famously storied.
