The population density of Monaco is one of the highest in the world, with over 25,000 people per square kilometer. This small city-state, located on the French Riviera, covers an area of just 2.02 square kilometers, making its compactness even more significant. Factors contributing to its high density include its status as a luxurious tourist destination, its financial services sector, and its appeal as a residence for wealthy individuals. The high population density presents challenges, particularly in housing and urban planning, reflecting the unique dynamics of this microstate.
