This chapter defines risk and reviews the concepts of causation from Aristotle, Hume, Mill, Koch, and Bradford Hill to Rothman; the use of ratio and difference measures in quantifying association; and attributable risk and its variants in assessing causal effect. It also explains the concept of competing risks and how they affect overall pattern of mortality. It discusses risk perception and communication as critical functions of public health practice.

Keywords: risk; necessary cause; sufficient cause; temporality; dose-response; relative risk; attributable risk; Koch's postulates; Bradford Hill's criteria; Pascal's wager
