Prevalence of dementia varies by jurisdiction

The age-standardized prevalence rate of dementia in Canada is 6.8%. There is provincial and territorial variation in the prevalence of the diagnosed disorder. While the data captures differences in population health status, geographical variations may also reflect differences in data availability and collection methods. Note that due to coding differences in physician-level billing data, Saskatchewan data is excluded from publicly reported CCDSS dementia prevalence for all years.
