Araruama, Brazil

With a population of just 59,024, Araruama may seem like a sleepy seaside town, but the reality is anything but. This municipality in Rio de Janeiro state is growing rapidly, driven by a booming real estate industry and tourism. However, the bureaucracy can be a persistent headache, and the city's geography - marked by lagoons and a large bay - means the climate can be quite humid.

Araruama's economy is diverse, with industries ranging from salt production to construction. Tourism is a major driver, with the city's beaches and lagoons attracting visitors, especially during peak seasons like Christmas, New Year's, and Carnival. But the population growth has been uneven, with some districts developing faster than others.

Overall, Araruama could be an appealing option for those seeking a laidback coastal lifestyle, but the administrative challenges and subtropical climate won't be for everyone. This city is best suited for those who prioritize proximity to nature and a lower cost of living over urban amenities.
