Many people regard Hong Kong as one of the countries with the highest population density in the world. To a large extent, that is absolutely true. Based on their population of 7,182,724 (July 2013 estimate) and their land size of 1,054 square kilometres (sq. km), the population density works out to be 6,815 residents per sq. km!
However, did you know that Singapore has a much higher population density?
