Campina Grande, Brazil

With a population of 326,307, this Brazilian city is no quaint village. While Campina Grande may have a rich cultural history and a thriving tech sector, the reality is that life here comes with some serious tradeoffs. The bureaucracy is a persistent headache, as evidenced by the city's long struggle to establish a formal government structure. And the climate, with its dry-summer tropical savanna bordering on a hot semi-arid climate, is hardly a selling point. Campina Grande may offer opportunities, but it's not for the faint of heart - this is a city best suited for those with grit, determination, and a high tolerance for red tape.
