In February 2007 the Alzheimer's Society published a major study on the social and economic impact of dementia in the UK.
The research, commissioned through King's College London and the London School of Economics provided a detailed and robust picture of prevalence and economic impact of dementia in the UK at that time.
The report showed that as the UK's population ages the number of people with dementia will grow substantially. It also showed that dementia cost the UK £17 billion a year.
Alzheimer's Society has now updated this research, for more information about current statistics please see Dementia UK: Update.
What did the report find?
- There were 700,000 people with dementia in the UK in 2007.
- There were 15,000 younger people with dementia in the UK in 2007. This is likely to be a major underestimate by up to three times because of the way the data relies on referrals to services.
- There were 11,500 people with dementia from black and minority ethnic groups in the UK in 2007.
- There will be over a million people with dementia by 2025.
- Two thirds of people with dementia are women.
- The proportion of people with dementia doubles for every 5 year age group. One third of people over 95 have dementia.
- 60,000 deaths a year are directly attributable to dementia. Delaying the onset of dementia by 5 years would reduce deaths directly attributable to dementia by 30,000 a year.
- The financial cost of dementia to the UK in 2007 was over £17 billion a year.
- Family carers of people with dementia save the UK over £6 billion a year.
- 64% of people living in care homes have a form of dementia.
- Two thirds of people with dementia live in the community while one third live in a care home.
