Download the evidence
The downloads contain optional population and housing context for the location register. Empty cells mean the measure is unavailable or not applicable; they do not mean zero. The JSON also retains special profiles, Scottish council context and source table references. This is a compilation of different statistical series, not a new survey of cleaning customers.
England: 367 places
Population, accommodation and tenure use the individual built-up-area tables, excluding London. London uses the London regional housing bulletin, while Westminster uses its local-authority profile. Those two special profiles do not have an invented built-up-area population or accommodation table. Published table values are retained; suppressed values remain absent.

Scotland: 31 places
Population uses NRS mid-2020 localities. The 2025 dwelling, vacancy and density context is council-wide and remains separately labelled. Household tenure comes from Understanding Scottish Places Census 2022 town profiles, a Scottish Government-commissioned resource. The three series are not combined into a population trend or a common geographic denominator.

Wales: 21 places
Welsh entries use the population, accommodation and tenure tables for individual built-up areas. These statistical areas are distinct from council boundaries. Official cities are retained even when below the large-place threshold. English and Welsh name aliases are included in the directory where present in the location register.

Northern Ireland: 17 places
Population uses MS-A01, accommodation uses MS-E06 and tenure uses MS-E15. Accommodation percentages are calculated from each category count and that table’s household denominator. Tenure combines the relevant owned, social and private/rent-free categories within its own table. NISRA settlement estimates and disclosure controls mean totals should not be forced to reconcile between different tables.

Selection and boundaries
The register includes 76 official UK cities and named built-up areas or localities with at least 25,000 residents in the selected England, Scotland and Wales series. Northern Ireland includes settlements with at least 18,000 residents, following its large-town threshold, plus official cities. This is a reproducible city and large-town scope, not a list of every village or neighbourhood. Metropolitan and combined statistical areas retain their original names.

Calculations and limitations
Accommodation shares describe households, not residents. Where published, percentages are kept as supplied and displayed to one decimal place. Tenure ownership combines owned-outright and mortgage, loan or shared-ownership categories in the ONS and NISRA tables. The Scottish profile supplies its own grouped values.
Statistical boundary, reference year and table definition must match before figures are compared. A council conservation-area count cannot be described as a count for a smaller built-up area. None of these measures establishes a home’s condition, construction material, cleaner availability, prices or completed work.
Attribution and reuse
ONS, NRS, NISRA and Understanding Scottish Places are the underlying sources, as identified beside each measure. Refer to their published terms for reuse of their material. No endorsement by a source organisation is implied. When citing this compilation, include the page, source organisation, reference year, geographic definition and the date you accessed it. Please link to the original evidence as well as this explanation.
