Definition 2

In connection with vital events, age data refer to the age on the day the event took place. Average age is obtained by adding up the ages of all persons involved in the same event at the time of the event, after which the sum is divided by the number of these persons. As the used age of a person is given in full years at the time of the event, it is not the exact age of that person. For this reason, it is assumed when computing average age that the persons were aged x+0.5, on average, at the time of the event.
