Benjamin Constant, Brazil

With a population of just 40,509, this remote Amazon outpost is hardly the cosmopolitan paradise some expats dream of. Despite its namesake's role in founding the Brazilian republic, the bureaucracy here is a persistent headache, and you'll feel underpaid and unhappy as a soldier, much like Benjamin Constant himself. The climate is tropical, the border with Peru is nearby, and the town's namesake was an intellectual at heart - so if you're a positivist-leaning, Comte-reading intellectual, this might be your kind of place. Otherwise, look elsewhere.
