This chapter covers the topic of offender mobility, an area of research concerned with the movement and search patterns used by offenders in the commission of crime. There are two parts to this overview. The first deals with the journey-tocrime literature, which covers how far offenders travel to commit crime and the pathways that they take to get there. This is a fairly well-established and rich area of enquiry that forms the bulk of the empirical evidence regarding offender mobility. The second part of this chapter focuses on an emerging but growing body of offender location choice studies. These aim to estimate relationships that influence where offenders choose to offend. While they use quite sophisticated statistical techniques, I will explain the logic of these types of studies without getting mired in the technical details of the methodology.
