Rate A rate, also known as an incidence rate or incidence density, is a measure of how quickly the health outcome is occurring in a population.

WebIncidence can also be expressed in terms of person-time at risk. Rates are usually expressed per 100, 1,000, or 100,000 persons. In a strict application, "rate" should only be used when the denominator is an estimate of the total person-time at risk. (You will find the term "rate" used inconsistently in epidemiologic reports.
