Diadema, Brazil

With a population of 305,287, Diadema is a dense, urban center in the heart of industrialized São Paulo state. The city's service sector dominates its economy, though healthcare facilities account for a surprising 77 installations. However, Diadema's geographical location between the coast and plateau has led to a web of roads and bureaucracy that are a persistent headache for residents. While the city is home to attractions like a butterfly zoo and art museum, its industrial roots and suburban sprawl make it better suited for pragmatic professionals than those seeking an idyllic Brazilian lifestyle.
