What is an “age-specific” incidence rate?
An age-specific incidence rate is the number of newly diagnosed cases of a disease in a specific age group in a particular population over a specified time period per “x” number of people in that age group. Typically, five-year age groups (0-4, 5-9, 10-14, etc.) are used. The time period is usually one year and the “x” number of people in the specific age group is usually 100,000.
