Three-Year Averages
The statistics in this report, including the number of cases, number of deaths, age-standardized
incidence rates (ASIR), and age-standardized mortality rates (ASMR) are presented as threeyear averages. Averages are used to smooth out year-to-year fluctuations so that the underlying
trend may be more easily observed. This smoothing of trends is especially important when the
number of cancer cases per year is relatively small. Three-year averages also more accurately
reflect the situation in RHAs, especially the smaller ones, where year-to-year variability can be
quite large. To calculate a three-year average for the number of events, the annual numbers are
summed for three years and divided by three.
The three-year averages for age-specific rates are calculated using the number of events
occurring in three years and dividing by the total population in the age range for the three years
of interest. ASIRs and ASMRs are then calculated from the age-specific rates.
Notes:
Three-year moving averages are age-standardized to the 1991 Canadian population. For
comparative purposes, age-standardized incidence rates for all of Canada are included. While
the most current Alberta data extends to 2003 (shown in the 2002 average), the most recent
Canadian data only extends to 2002 (shown in the 2001 average). Please note that some
graphs may not include Canadian rates as some national rates were not available from
Canadian Cancer Statistics: 2006, Canadian Cancer Society.
