incidences, plural;
  1. The occurrence, rate, or frequency of a disease, crime, or something else undesirable
    • - an increased incidence of cancer
  2. The way in which the burden of a tax falls upon the population
    • - the entire incidence falls on the workers
  3. The intersection of a line, or something moving in a straight line, such as a beam of light, with a surface


  1. the relative frequency of occurrence of something
  2. the striking of a light beam on a surface; "he measured the angle of incidence of the reflected light"
  3. Incidence is a measure of the risk of developing some new condition within a specified period of time. Although sometimes loosely expressed simply as the number of new cases during some time period, it is better expressed as a proportion or a rate with a denominator.
  4. In geometry, the relations of incidence are those such as 'lies on' between points and lines (as in 'point P lies on line L'), and 'intersects' (as in 'line L1 intersects line L2', in three-dimensional space). That is, they are the binary relations describing how subsets meet. ...
  5. In mathematics, a graph is an abstract representation of a set of objects where some pairs of the objects are connected by links. The interconnected objects are represented by mathematical abstractions called vertices, and the links that connect some pairs of vertices are called edges. ...
  6. the frequency with which epilepsy occurs over time; about 200,000 epilepsy cases develop in the United States each year.
  7. the extent or frequency of an occurrence; the number of specific new events in a given period of time.
  8. In epidemiology, the number of cases of disease, infection, or some other event having their onset during a prescribed period of time in relation to the unit of population in which they occur. Incidence measures morbidity or other events as they happen over a period of time. ...
  9. the number of new cases of a disease occurring in a given population over a certain period of time.
  10. The frequency of new infections during a designated time period expressed.
  11. A contrasting term to prevalence. Incidence tells us the frequency of occurrence of some event during a particular time period. For example there were 581 criminal homicides in 1997, or the rate of crime for one year is higher than for the previous year.
  12. is a measurement of the number of new individuals who develop a condition during a particular period of time. Incidence conveys information about the risk of developing the condition. For example, approximately 200,000 people develop neovascular age-related macular degeneration each year in the U.S.
  13. the rate of occurrence of some event, such as the number of individuals who get a disease divided by a total given population per unit of time.
  14. n.  ~ of sth extent to which sth happens or has an effect
  15. The rate at which an event occurs in a defined population over time. To be distinguished from prevalence.
  16. A measure of new claim incurral activity usually tracked as a percentage of new claims submitted and payable within a specific reference period.
  17. The frequency of something occurring in the population. It usually refers to persons and is stated as a percentage (i.e., the percentage of people in the Canada, who eat visited a fast food restaurant in the past month). ...
  18. the number of newly identified cases of a condition or event in a given time period, usually in a year. Often expressed as a figure per 100,000 population.
  19. The number of new cases of a condition detected annually, per unit of the population. For genetic conditions, the incidence is quoted as the number of affected individuals per 1,000 births whether detected at birth or not.
  20. There are two central aspects of psychotropic drug response, (1) the proportion of patients in whom a therapeutic response is induced ("incidence") and (2) the time to onset of improvement ("latency"). These two aspects are analyzed by means of 1-dimensional or 2-dimensional cure models.
  21. Rate of new cases of disease occurrence.
  22. The rate of new cases of a disorder over a specified period of time. See also prevalence.
  23. The number of people newly diagnosed with a specific disease or disorder during a single year.
  24. The rate at which an event occurs, such as the number of new breast cancer cases per year.
  25. Concerns the frequency of new cases. Can be expressed as number of new disease cases accumulated over time (cumulated incidence proportion), or as the >velocity< at which new cases arise (incidence rate).
