Cajamar, Brazil

With a population of 92,689, Cajamar is no quaint backwater. The cost of living may be lower than Brazil's big cities, but bureaucratic hurdles are a persistent headache. Crime is an ever-present concern, with locals citing safety as a major issue. For those undeterred by the administrative hassles and willing to navigate the city's challenges, Cajamar could offer an affordable alternative to the country's pricier urban hubs.
