Asia is the continent with the highest population density. It is home to over half of the world's population, with major countries like China and India contributing significantly to the numbers. Urban areas within Asia, such as Tokyo, Mumbai, and Shanghai, experience extremely high population densities due to rapid urbanization and migration. Dense populations arise from a combination of factors, including economic opportunities, cultural significance, and historical development. While some regions in Asia are densely populated, others remain sparsely populated, highlighting the continent's vast geographical and demographic diversity.
