Canadian Cancer Registry

Age-standardization: incidence

The Canadian Cancer Registry (CCR) uses age-standardization to enable comparisons of incidence rates over time or across geographic regions that are unaffected by changes in the age distribution of the population. Specifically, the July 1, 2011 Canadian population (final postcensal version) is used as the standard population for Table 13-10-0747-01. The age-standardized rates can be interpreted as the rates that would have been observed if the populations of interest had the same age distribution as the standard population.
