This chapter discusses rates and probabilities in epidemiological analysis. A rate is defined as an instantaneous measure of change per unit time. A rate calculated from epidemiologic data reflects risk. A probability is another widely used measure of risk, distinct from a rate, but plays a similar role in epidemiologic analysis. Survival probabilities and hazard rates, statistical properties of probabilities calculated from mortality or disease data, and analysis of rates are discussed.
