The most populated country in the world is China, with a population that exceeds 1.4 billion people. According to estimates, China has maintained this status for many years, primarily due to its extensive land area, urbanization, and significant historical growth patterns. While China’s population has been rising, it has also seen shifts due to government policies, such as the former one-child policy. In recent years, India has been closing in on China's population numbers, leading to predictions that India may surpass China as the most populous country in the near future.
