Ernst Ravenstein

Ernst Ravenstein was a German geographer and demographer best known for his migration theories in the late 19th century. He proposed that migration is influenced by economic factors, suggesting that people move from areas of low opportunity to regions with more job prospects. Ravenstein formulated several "laws of migration," highlighting patterns such as the tendency for migrants to move short distances and for most to settle in urban rather than rural areas. His work laid the groundwork for understanding human migration patterns and influenced later studies in geography and social sciences.
