It has an area of 1.98 km2 (0.76 sq mi), and a population of 36,371, making Monaco the most densely populated country in the world.

After a recent expansion of Port Hercules, Monaco's total area is 2.05 km2 (0.79 sq mi), with new plans to extend the district of Fontvieille, with land reclaimed from the Mediterranean Sea. Economically the principality's mild climate, splendid scenery, and gambling facilities have made Monaco a destination for the rich and famous. However, in more recent years Monaco has become a major banking center holding over €100 billion worth of funds and has successfully sought to diversify its economy. The state has no income tax and low business taxes, and is well known for being a tax haven. Monaco boasts the world's highest GDP nominal per capita at $153,177 GDP per capita at $132,571, GNI per capita at $183,150, and over 48,000 workers who commute from France and Italy each day.
