Why is Assam thinly populated where as Bihar is densely populated?

Answer 1

Assam is thinly populated due to its geographical challenges, including hilly terrains and frequent flooding from the Brahmaputra River, which limit agricultural expansion and settlement. In contrast, Bihar has a flatter landscape with fertile soil that supports extensive agriculture, leading to higher population density. Additionally, socio-economic factors, such as better job opportunities and infrastructure in Bihar, attract more people to settle there. Historical population growth patterns and migration also contribute to the differences in population density between the two states.
