Dementia Maps
The interactive maps below show the number of people living with dementia in different parts of the UK based on published population and prevalence data. In areas with larger and older populations, there will be a higher number of people living with dementia, as age is the greatest risk factor.
The Integrated Care Board (ICB) map for England includes the number of people with a diagnosis of dementia and the diagnosis rate for each ICB area, based on NHS England data. ICBs are statutory bodies that are responsible for planning and funding NHS services in the area. You can find statistics on diagnosis rates here.
