title: Methods of age adjustment.
abstract: Absolute numbers of cancer cases or deaths in a population depend, first, on the size and, second, on the age composition of the population. In order to present incidence and mortality statistics in a comparable fashion methods of age adjustment are indispensable. In this paper the concepts and methods available for calculating age-standardized rates, truncated rates, and cumulative rates are reviewed and examples presented.
