Georg von Ravenstein was a notable German geographer and cartographer, born in 1816. He is best known for his work in the field of population geography and for developing the concept of migration laws. His research focused on understanding the patterns and trends of human movement, which laid the groundwork for future studies in this area. Ravenstein's most significant contributions include the formulation of several principles that describe why and how people migrate. His work emphasized factors such as economic opportunities and social connections, influencing later theories in human geography and demography. He passed away in 1884, leaving a lasting impact on the study of population dynamics.
