Campos dos Goytacazes, Brazil

With a population of just 389,109, Campos dos Goytacazes is hardly a bustling metropolis. This sleepy city on Brazil's northern coast lacks the excitement of Rio, but its economy is propped up by oil extraction - for better or worse. The per capita income is a respectable R$35,475, but the city also has the dubious honor of being the most violent in southern Brazil, with 46 homicides per 100,000 residents in 2018. And while the tropical climate may seem idyllic, the region is prone to heavy rainfall, with records of over 150mm in a single day. Overall, Campos is a quiet backwater better suited for those seeking a slower pace of life than big-city thrills.
