Almost all diseases or health outcomes occur at different rates in different age groups. Many chronic diseases, including most cancers, occur more often among older populations. Other outcomes, such as many types of injuries, may occur more often among younger people. Therefore, the age distribution of a given population often determines what the most common health problems in a community will be. Age-adjusted rates are essential for evaluating public health events that vary with age (for example, cancer deaths), or when comparing populations with different age distributions such as in Ocean County with a diverse age distribution.
