Select the Age Variable to be used for linking population and standard population data. The selected variable will determine which age variables are displayed on the Statistic tab.
A large number of incidence and mortality databases are provided with the software. There are multiple databases that use the same case or mortality data but differ in terms of the population data. That is, different variables are used to link the case (or death) data to the population and standard population data.
For example, in a Rate or Limited-Duration Prevalence session, you may see a set of databases with names similar to those shown below.
Incidence - SEER 9 Regs Limited-Use, Nov 2002 Sub (1973-2000)
Incidence - SEER 9 Regs Limited-Use, Nov 2002 Sub (1973-2000) <18 Age Groups>
These databases contain the same incidence data, but are linked to the population and standard population data with different age variables. In one case, an age variable with 19 age groups (< 1, 1-4, 5-9, ..., 85+) is used. In the other case, an age variable with 18 age groups (0-4, 5-9, ..., 85+) is used. Only one of these databases will be listed in sessions that do not use population or standard population data, such as Frequency sessions.
