Systems and methods for generating a social topography map based on user affinity concentrations are disclosed. In general, locations and aggregate profiles are obtained for a number of crowds of users that are relevant to a geographic bounding region for a desired social topography map. Each aggregate profile includes information regarding an affinity between a corresponding crowd and a defined user profile. The defined user profile may be a user profile of a requesting user, or a select subset thereof, or a target user profile. Social topography data for the desired geographic bounding region is then generated based on the locations and aggregate profiles of the relevant crowds. The social topography data defines user affinity concentrations across the desired geographic bounding region. A social topography map may then be generated and presented to a requesting user based on the social topography data generated for the desired geographic bounding region.
