Spatial mobility emerges as a key driver of urban evolution, characterized by situation-specific combinations of opportunities, restrictions, and fears.

One revolves around problems of definition, both in terms of demarcating cities from their surroundings and of distinguishing migration in a narrower sense from other forms of short- and long-distance mobility. Further shared concerns include the integration of multiple analytical scales, contextual factors, and diachronic variables (such as urbanization, industrialization, and the digital revolution). weiterlesen
