in·ci·dence

 (ĭn′sĭ-dəns)
n.
1. The rate or extent of occurrence or effect: a high incidence of malaria in the tropics.
2. Usage Problem The fact or an instance of happening; occurrence: did not expect criticism and was surprised by its incidence.
3. Physics
a. The arrival of radiation or a projectile at a surface.
b. Angle of incidence.
Usage Note: The singular noun incidence and the plural noun incidents sound alike and are sometimes confused. In its main (and, many would insist, proper) use, incidence refers to the rate at which something happens, as in The city has taken measures to reduce the incidence of vandalism. An incident is a discrete event, so proper use in the plural would be There were fewer incidents of vandalism in schools last year. Confusion arises because incidence is sometimes used for the fact or an instance of occurrence, especially in the plural, as in Incidences of religious intolerance are on the rise, creating tensions within many communities. Although sentences like this one can be justified as referring to rates of occurrence, it is unlikely that readers will interpret them in this way without explicit indication of what is meant. Many people consider such usages to be infelicitous, if not wrong. In our 2002 survey, 67 percent of the Usage Panel found the sentence on religious intolerance unacceptable.
