Mangaratiba, Brazil

With a population of just 17,925, Mangaratiba is a sleepy coastal town that offers little for most expats. The port sees heavy traffic from bulk carriers ferrying iron ore, but the local economy revolves around little more than basic services.

A "strong political crisis" has plagued the town in recent years, with multiple mayors arrested during their terms. This persistent bureaucratic headache is a major deterrent for anyone seeking stability or efficient local government.

Mangaratiba may appeal to those seeking a remote, laidback lifestyle on Brazil's coast, but the lack of economic opportunity and chronic political dysfunction make it a poor choice for most would-be expats.
