Demographics dataset#

Last modified: 09 Sep 2025

Basic information about all NHS patients in England, Wales and the Isle of Man.

1. Summary#

The Demographics dataset is derived from the Personal Demographics Service (PDS) database, which is the national database of all NHS patients in England, Wales and the Isle of Man in or after 2004. People born in these areas are registered and issued an NHS number at birth; people moving into these areas are registered when they first interact with an NHS care setting. Data collected include NHS numbers and date of birth, name, sex and address. A sub-set of this dataset (DEMOGRAPHICS_SUB) containing Study ID, data of birth and sex is provisioned with all NHS England data requests.

4. Documentation#

We are currently building a documentation storage system which will host useful documents related to datasets and data owners. We will surface these documents on Guidebook.

5. Useful Syntax#

Below we will include syntax that may be helpful to other researchers in the UK LLC TRE. For longer scripts, we will include a snippet of the code plus a link to the UK LLC GitHub repository where you can find the full scripts.
