Country
Technically, Monaco has the world’s highest population density (about 43,000 people per square mile), yet Monaco itself has an area of less than 1 square mile (3/4 square mile) and a population of only 32,000. For this reason, people exclude the microstates of Monaco, Singapore, Malta, and Bahrain in discussions of population density and skip directly to Bangladesh which has 2,637 people per square mile.
