Irati, Brazil

47,854 residents may sound quaint, but the reality is this small Brazilian town has more bureaucracy than charm. Irati sprang up in the 1890s as a railroad hub, with a population today that's predominantly Polish and Ukrainian. While they maintain customs of their ancestors, the climate is decidedly less hospitable - warm summers and abundant rainfall punctuate the mild winters. A municipal anthem may seem a whimsical touch, but it's a persistent headache navigating local red tape. Unless you're drawn to the niche appeal of small-town southern Brazil, Irati likely has little to offer the average expat.
