Overview

Summary of dataset and variables

This shows the number of patients registered to practices in Wales by their country of residence (Wales or England) and the number of patients registered to practices in England who live in Wales. The data excludes English residents registered to English practices.

Data collection or calculation

This StatsWales cube is based on data extracted quarterly by NHS Shared Services Partnership (NWSSP) from the Welsh Demographic Service system. Data prior to October 2024 was extracted from National Health Application and Infrastructure Services (NHAIS).

The quarterly data from January 2020 are extracted around the middle of the month, usually between the 10th and 16th. Note the exact date of extraction is not known for the four quarters of 2020.

The data excludes English residents registered to English practices.

Data for English practices are not at practice level and are aggregated.

Note this StatsWales cube includes some Welsh practices that are not subject to the General Medical Services (GMS) contract.

Statistical quality

The LSOA of residence is sometimes not known for some patients and varies between around 100 and 600 patients each quarter.

No data is available for April 2022.

For July 2024, the data for English residents registered to Welsh practices have been imputed using September 2024 data, due to data quality issues with the July 2024 data.
