Narail, Bangladesh

With over 788,000 residents packed into just under 1,000 square kilometers, life in Narail is a crowded affair. The district boasts a privatized app-based system for reporting corruption and social ills, a necessity in a region beset by bureaucratic headaches. Narail's subtropical climate, with temperatures ranging from 11 to 37 degrees Celsius and over 1,400mm of annual rainfall, can also be a persistent challenge. Overall, this dense, historically significant district may appeal to those drawn to its rural charms and cultural legacy, but the practical realities of living there are not for the faint of heart.
