As of 2009, almost one-third of seniors were in the 65 to 69 age group, and more than half were less than 75 years of age.
The number of seniors in older age categories has grown more rapidly than those in younger categories. In 2009, seniors aged 80 years and over made up more than one-quarter of all Alberta seniors, up from approximately 21% in 1974 (see Chart 2). This group is expected to more than double in the next 20 years.
