Age Variable for Rate Sessions

On the Statistic tab in a Rate session, if you choose age-adjusted rates or trends as your statistic, you must also select an age variable. This age variable defines the age groups used for age-adjusting.

The Age Variable for age-adjusting is always an age recode variable or a user-defined version of an age recode variable.  Only the age recode variable that is linked with the population and standard population data can be used. This variable differs from one database to another based on the associated population and standard population data. For example, some have 18 age groups while others have 19. Variables used for age-adjusting cannot have overlapping or duplicate age groups. If you exclude an age group, it will be included as its own grouping in the age-adjusting calculations.

Only valid age variables will be available in the Age Variable drop-down list on the Statistic tab.
