Food and drink on the high street

Counts are registered food premises in the South Mimms built-up area (710 residents at the 2021 census), from the FSA food hygiene register, extracted 17 August 2026. The boundary is drawn from where the buildings are, so these figures cover the town itself rather than the wider council area, and no total is shown because the register also lists premises nobody would call a venue: school kitchens, care homes, warehouses.

Shops and services

Shops, cafés, salons, banks, post offices and arcades are rateable premises by use on the VOA 2023 rating list — the shops figure is all general retail, charity shops included. Gambling premises come from the Gambling Commission's licensing register, which lists 6,251 betting shops nationally against the rating list's 3,838: many betting shops are rated as ordinary shops, so the licensing register is the truer count and the one used here. Categories the rating list counts badly are deliberately absent rather than wrong: petrol stations disappear into supermarket ratings, vets and museums run far under their professional registers, and pools and nurseries mostly rate inside other premises.

Crime, per 1,000 residents

The all-offences line is a count of records, not a safety score: it weighs every category equally, which is exactly why we publish the categories. We deliberately do not combine them into a single index.

Figures are police-recorded crime (August 2025 to July 2026) located to this built-up area, per 1,000 residents at the 2021 census. Three cautions, each of which changes how a rate should be read: recorded crime is not crime experienced, because reporting rates differ by category and by place; the denominator counts residents, so town centres and visitor towns run high per resident precisely because many people there are not residents; and a high figure can reflect more reporting as easily as more crime. Percentiles compare towns of 10,000+ residents. Greater Manchester and Gloucestershire constabularies do not publish, so their towns show a note instead of a partial figure. Compare towns →

Schools

The 2021 census counted 34 children aged 5 to 9 in the town: one state primary school for every 34 of them.

Open schools registered in the South Mimms built-up area, from the Department for Education's Get Information about Schools register, extracted 24 August 2026. Each school counts once: an independent special school appears under special schools, and the phase rows are state schools. Places are reported capacity and pupils each school's latest census return, summed only over schools reporting both, and shown only where at least 9 in 10 of a phase's schools do; state primaries across measured towns run at 89.2% of capacity, secondaries 91.3%. The children-per-school figure pairs a 2021 census count with today's register, so growth or decline since the census is not in it. No inspection grades are shown because Ofsted stopped issuing single-word overall judgements in 2024 and the register no longer carries them; current inspection reports are on Ofsted's own site. England only: the register lists Welsh schools without phase detail.

Broadband

Share of the 373 residential premises in this built-up area that the fixed network can serve at each speed, from Ofcom's Connected Nations coverage data (network state July 2025). Availability is what the line to a home can deliver if ordered, not what households actually subscribe to, and a full-fibre street where everyone bought the cheapest package shows 100% here.
