Over time, people change whom they interact with and where they are. Understanding how changes in social and geospatial relations interact is critical to a number of areas--from general social change to counternarcotics and counterterrorism. For instance, as terrorists attempt different tasks, they move to new locations and interact with different groups. This article introduces a simple theoretical multiagent model for reasoning about the criticality of agents and locations as agent interactions coevolve in geographical and social spaces. The model simulates social changes in whom agents interact with and spatial changes in where they relocate to as a function of learning and social-network evolutions. The analysis suggests that terrorists will disperse around the world rather than gather at a specific location. However, terrorists who have been the center of social networks will stay the same. This model helps us gain insights into the complexities of organizations evolving in the social and the geospatial dimensions simultaneously. This article is part of a special issue on social computing.
