Ernst Georg Ravenstein was a German geographer and cartographer, best known for his work in the field of migration studies. Born in 1834, he developed several principles of migration that are still referenced today, often referred to as the Ravenstein's Laws of Migration. His research emphasized the patterns and trends of human movement, contributing significantly to the understanding of demographic changes. Ravenstein's work laid the foundation for modern migration theory, influencing later scholars and researchers. He published numerous articles and studies, which highlighted the socio-economic factors driving migration. His insights remain relevant in discussions about urbanization and population dynamics in contemporary society.
