Figure 1-4 shows that prevalence increased in every age group over time. Although the actual number of Canadians with diagnosed diabetes has increased most rapidly in the older age groups, the proportion of individuals with diagnosed diabetes has increased more in younger age groups. Between 1998/99 and 2008/09, the greatest relative increases in prevalence was seen in the 35 to 39 and 40 to 44 year age groups, where the proportions doubled.
