Spatial Diffusion of the Crime Mapping Innovation in the United States

Sharon E. Chamard, Rutgers University

ABSTRACT
This paper concerns the nature of the spatial diffusion of crime mapping in American police departments. Did this innovation diffuse in accordance with the "neighborhood effect," which suggests innovations spread most quickly among those who are close to each other (e.g., Hagerstrand)? Or was propinquity less important than the reputations and connections of early adopters?
