Request received
Request received for dementia prevalence data by age band and sex at LTLA level.
Our response
This file contains the number of patients with a recorded diagnosis of dementia on their GP patient record at GP practices in England as at 31 January 2023, and the number of patients registered at those GP practices as at 1 February 2023. These counts are broken down into age/sex bands, and are aggregated to lower tier local authority (LTLA) level.
These figures are based on data collected as part of the Core GP Contract service, which is routinely published in the Primary Care Dementia Diagnosis data publication series, but not at LTLA level. The following should be borne in mind when interpreting these data:
- Data is only drawn from those practices from which data was extracted for the reporting month; this requires practices to have received and accepted an invitation to participate in the Core GP Contract 22/23 service.
- Figures will not exactly match corresponding figures in the Primary Care Dementia Data release. This is because:
- The PCDD publication uses historic data up to six months old where data are not available for a practice in the current reporting month. This imputation has not been applied to this dataset.
- Disclosure control has been applied to this dataset
- Values have been replaced with a * where either of the following criteria are met within an age/sex band for a given LTLA:
- The number of patients on the dementia register is equal to the number of registered patients.
- The number of patients on the dementia register is in the range 1-4 inclusive.
