Alzheimer Europe estimates the number of people with dementia in Sweden in 2012 as being 173,135. This represents 1.82% of the total population of 9,495,392. The number of people with dementia as a percentage of the population is somewhat higher than the EU average of 1.55%. The following table shows the estimated number of people with dementia between 30 and 59 and for every 5-year age group thereafter.

Statistics from the Swedish Dementia Registry (Svedem) are quite similar. Svedem estimates the number of people with dementia in Sweden in 2012 as being 160,000. The risk of developing dementia increases with age. Eight percent of those aged 65 or older and almost half of those 90 years or older have dementia. Dementia rarely affects people under 65. In Sweden, the estimated number of younger people with dementia is about 8,000 to 9,000, most of whom are aged between 60 and 65. Approximately 24,000 people each year develop some form of dementia and about the same number die of a dementia-related disease as a consequence of having dementia.

Approximately two thirds of people with dementia have been assessed and received a diagnosis of dementia. The National Board of Health and Welfare estimates that the effect of its recommendations on a basal and expanded investigation is that the number of investigations is increasing by about 7,000 inquiries annually.
