Tiny Monaco, located on the French coast on the Mediterranean Sea, is the second smallest and the most densely populated country in the world. With 36,000 people occupying an area of just around 2 square kilometres, the population density is around 18,000 people per square kilometre!
Any discussion of population density is incomplete without mention of Bangladesh. This small nation in South Asia has a population of 156 million (8th in the world), but an area of only 147,000 square kilometres (94th in the world). Incredibly, the population of Bangladesh is slightly more than that of Russia, while the area is less than 1% that of Russia! This huge disparity means that Bangladesh is the most densely populated large country in the world. The countries that rank above it in terms of population density are all tiny city-states such as Singapore, Monaco and Hong-Kong.
