The fundamental premise of this book, Epidemiological Criminology, is that it is important to adapt to the ever-changing scientific, theoretical, conceptual, and methodological landscape of different disciplines by learning how to gain new insight into issues and problems from various perspectives. The science and practice of epidemiology and public health, and of criminology and criminal justice, are our focus. Their individual disciplines are evolving to reflect the changing demographics, structures, and environments in which they thrive, which have compelled all of them to adjust to various points of view while not sacrificing their fundamental precepts. Epidemiology, for example, and its disciplinary counterpart, public health, share a common bond of a focus on disease.
