Dementia affects around 944,000 people across the UK with some areas having a greater number of people living with dementia than others.
To help show this distribution, the maps linked below provide a visual and interactive representation of dementia prevalence by four different geographic entities; Westminster constituencies for the UK, Integrated Health Boards for England (replacing Clinical Commissioning Groups as of July 2022), and Local Health Boards for Scotland and Wales.
These tools are developed by using published population data and prevalence rates of the condition to estimate the total numbers of people in each area with dementia, for 2015. Each five-year age band from 30-34 up until 95+ has an associated dementia prevalence rate (an estimated percentage of that age group with dementia) from the Dementia UK: Update 2014 report and these rates are then multiplied by the population data.
In areas with larger populations and older populations, there will be a higher number of people living with dementia, as age is the greatest risk factor.
