Incidence
...That is a measure of the risk of developing some new condition within a certain period of time. The incidence rate is the # of new cases per population that develop a disease over a period of time. So, in a population of 100, if 5 people develop the disease within 5 years, the incidence rate is 5% over 5 years. Compare to 'prevalence', which measures the total # of cases per population.
