Planaltina, Brazil

With a population of 189,412, Planaltina is a sprawling, under-developed administrative region within Brazil's Federal District. While the traditional city center maintains quaint 19th-century architecture, the newer neighborhoods are plagued by shoddy infrastructure - over 80% of residents lack proper drainage and nearly 30% have no public lighting. The bureaucratic headache is persistent, as Planaltina's territory was divided between the Federal District and the state of Goiás when Brasília became the capital. For those seeking an authentic small-town vibe, Planaltina may have a certain charm, but the lack of basic services makes it a tough sell for most.
