  1. Proportions (%) of the currently registered acceptable populations of England, Northern Ireland, Scotland, and Wales assigned to each higher-level ethnic category by the algorithm in CPRD GOLD-HES, CPRD Aurum-HES, and CPRD-HES for patients with at least one ethnicity record compared to the proportions of each general population in each higher-level ethnic category in the UK Census 2011, the experimental ethnicity distributions for England and Wales from ONS in 2019, and the ethnicity distribution for England from the NHS Digital General Practice Extraction Service (GPES) Data for Pandemic Planning and Research (GDPPR) with Hospital Episode Statistics (HES) in May 2021. Scotland and Wales are not currently represented in the CPRD Aurum database
