How these figures are made
Counts are h3hex's own store-by-store record of each brand's published UK locations for the brands listed in the Mainstream supermarket sector of the h3hex data store, November 2026 release (scrape window 30 Oct - 3 Nov 2026), page built 2026-11-12. Closed, pre-opening and head-office records are left out. 9 outlets with no mappable postcode are counted in the totals but not in the local-area tables. 4 districts created in 2023 are shown by their ONS code because the postcode lookup used here carries no name for them. Net change compares this release with the 29 October 2026 edition of the same dataset and reflects openings and closures as well as improved coverage of each brand's own locator. Resident population is Census 2021 usual-resident population by output area, summed to local authority district through the ONS postcode-to-output-area lookup (May 2024). The population table does not join to the lookup for districts in Northern Ireland and Scotland, so outlets per 10,000 residents is shown as - for them.
