Torsten Hägerstrand (Swedish geographer)

He developed theories and models to understand how people travel, where they go, and how their routines influence the spread of ideas, culture, and even diseases. His research helps explain how individuals’ daily activities and social interactions shape the geographic distribution of populations over time. Hägerstrand's work laid the foundation for studying spatial behavior, emphasizing that human movement is structured by social, economic, and personal factors, and plays a critical role in understanding societal and environmental change.
