Plains tend to be more fertile and have better access to water sources, making them suitable for agriculture which can support larger populations. Additionally, the flat terrain of plains makes it easier to build infrastructure and transportation networks, attracting more people to settle in these areas. This increased population density on plains can also create economic advantages and opportunities that further contribute to their high population.
