Norfolk population
Dementia
Applying the dementia UK report estimates of population prevalence of late on set dementia and applying these to the 2021 population derived from the 2021 census, the number of people aged 60 years and above living in Norfolk with dementia was estimated to be 16,691 during 2021.
Diagnosis rate
In January 2022 NHS digital recorded 9,509 people in Norfolk diagnosed with dementia against an estimated prevalence of 17,104 people which is a diagnosis rate of 55.6%.
Stages of dementia
Research by the Alzheimer's Society (2020) and by Wittenberg (2019) estimate that the proportion of people with mild, moderate, and severe dementia is:
- Mild dementia: 14%
- Moderate dementia: 28%
- Severe dementia: 58%
This would mean that for Norfolk, of the 17,104 people estimated to have dementia in 2022:
- 9,920 people will have severe dementia
- 4,789 people will have moderate dementia
- 2,395 people will have mild dementia
This would suggest that the people diagnosed with dementia in Norfolk are those with severe symptoms.

- 2030: 20, 579 people with dementia

The impact on adult social care in Norfolk
It is estimated that one in 20 people nationally with dementia are aged under 65 years of age.
This will be a key driver of social care demand, primarily in the older people's care market, but also impacts learning disabilities, autism, and mental health services catering for older care users.
