Method: Mid-year population estimates

ONS mid-year estimates are modelled from the 2021 Census, births, deaths and migration. Mid-2022 is the revised series. Ages are grouped: 0-15 means ages 0 to 15 inclusive, working age 16-64, 65 and over. Change 2022-2024 compares the revised mid-2022 with mid-2024 estimates for the same boundaries. Scotland and Northern Ireland: mid-year estimates for council areas published by ONS from National Records of Scotland and NISRA (via Nomis), for 2022 to 2024, to match the England and Wales years. No small-area (ward or neighbourhood) estimates are held for them.

Method: Price paid medians

Sales are mapped from postcode to each geography exactly. The headline is the median sale price over the latest 12 COMPLETE months (a month is complete when national standard sales are at least 85% of the average of the 24 months before it; currently November 2024 to October 2025) and the 12 months before that. Months after that (Nov 2025 onward in the April 2026 extract) are still being registered and are excluded. Yearly medians use complete calendar years 2016-2024. Medians need at least 10 sales; sales counts are published for any area. Medians describe homes that sold, not all homes, and are not adjusted for the mix of property types, so a change in the median can reflect what was sold. Registration lags completion, so recent months can be revised up. Only standard price paid sales (category A) are included.

Method: Census 2021 housing, health and qualifications for Wales

Wales held its census on the same day as England (21 March 2021) with the same questions, so the figures are directly comparable. For Wales we use the published local authority tables. Tenure counts shared ownership with owners; "private rented" includes people who live rent free, as in the England figures. Overcrowding is an occupancy rating of -1 or less for bedrooms. Qualifications are for people aged 16 and over; "no qualifications" and "Level 4 or above" (degree level and above) are shares of all those people. Counts are rounded by random adjustment, so tiny differences from other tables are expected. Wales households per local authority are not split to small areas here.

Method: Registered companies by area

Companies are placed by the postcode of their REGISTERED OFFICE, which is not a trading or operating location: accountants, formation agents and virtual offices register thousands of companies at one address, and many small companies use a director's home. Counts are of companies with status Active (including those with a proposal to strike off), by the section of their first listed SIC 2007 code. Incorporation counts cover companies incorporated in the window that are still on the register at 2 Oct 2026, so dissolved companies are missing and older windows are understated relative to newer ones. Companies per 1,000 residents divides by the mid-2024 resident population (England and Wales only) and is not a measure of business density where registration hubs exist. SIC section Z groups dormant, non-trading and unclassified companies.

Method: Recorded street crime per 1,000 residents

Counts of crimes in police.uk street-level data for May 2025 to April 2026, matched to 2021 LSOAs by the LSOA code on each record, then split to output areas by population and rolled up (see the area apportioning method). Rates are crimes per 1,000 residents (mid-2024 population) and describe where crimes were recorded, not who committed them or where victims live. High rates occur where many non-residents pass through (town centres, transport hubs, nightlife), so they are not a measure of risk to residents. Crimes with no location (blank LSOA) are excluded; the excluded share by force is in the notes. Greater Manchester Police data are absent from the extract, so those areas have no value. Categories follow police.uk. Anti-social behaviour is incident data, not crime proper, and is included only in the "all categories" rate. 12 months only: no trend is possible and seasonal effects are included.

Method: Charities in an area

A charity is placed by the postcode of its registered/contact address (or the nearest postcode to its geocoded address; some are placed by the nearest postcode to a geocoded address), so counts show where charities are based, not where they work: a national charity with a London address is counted in London. Income is the latest annual income on the register, summed; it is dominated by a few very large charities. "Declaring the area" counts charities that name the local authority (or its county) as an area of operation on the register; it does not mean services are delivered everywhere in that area. Registered charities only; unregistered community groups, small charities below the registration threshold and removed charities are not counted.

Geography

Constituency, compared with Wales

Method

Company dissolutions and net formation. Dissolutions are companies Companies House records as dissolved, counted on the dissolution date and located by the postcode of the registered office held at dissolution. That address is often an accountant, formation agent or liquidator, not where the company traded, so it says where a company was registered, not where a business closed. Every dissolution day since 1 January 2010 was fetched one day at a time and checked: the number of companies stored equals the number the register reports for that day. The latest window is the 365 days ending the latest complete day; the prior window is the 365 days before it; annual figures are complete calendar years. The route to dissolution (strike-off, end of liquidation, merger) is not recorded, so dissolutions are not split. Net formation = companies incorporated in the period (all that were ever registered in it, whether or not they have since been dissolved) minus companies dissolved in the period. The two groups are different companies and are located by different addresses, current for companies still on the register and last held for dissolved ones. Net formation compares registered offices, not jobs, trading or business closures.

Limitations

Registered offices are not operating locations; many companies are registered at an agent or accountant address.
Registered-office events are not new local employers, closures or job changes.

Office for National Statistics: Price Index of Private Rents, UK: monthly price statistics (Open Government Licence v3.0)

Period

Aug 2026

Geography

Council area, compared with Wales

Method

Private rents (PIPR). The ONS Price Index of Private Rents measures the change in rents paid by private tenants, and publishes an average (mean) monthly rent per local authority from the same data. The figure is a mean, not a median, so a few very high rents pull it up, especially in London and where there are few lettings. It covers rents paid for homes let on the private market (not social rents) and reflects all tenancies in the stock, not only new lets, except in Scotland where the underlying data are mainly advertised new lets, which makes Scotland not directly comparable with England and Wales. Annual change is the change in the rental price index, not in the cash average. Rents are in cash terms, not adjusted for inflation. Averages by number of bedrooms are held for the latest month only.

Limitations

Change in the rental price index.

Period

Geography

Council area, compared with same place, 2022

Method

Earnings from the Annual Survey of Hours and Earnings. ASHE is a 1% sample of employee jobs from HMRC PAYE records, with a reference week in April. We hold the median gross pay of full-time employees, by place of residence (where the employee lives) and by place of work (where the job is), for the latest survey year and the years back to 2015. Median weekly pay is gross pay before tax for the pay period that includes the reference date; annual pay is gross annual pay for the year to April. Pay is in cash terms: it is not adjusted for inflation, so changes over time include price rises. Survey estimates have a margin of error that grows as areas get smaller; each value carries its coefficient of variation and values with a CV above 10% are marked low quality. Estimates ONS judges too unreliable (CV above about 40%) are not published and appear here as absent. Self-employed people are not covered. Residence-based figures describe people who live in the area wherever they work; workplace-based figures describe jobs located in the area wherever the employee lives. The two can differ a lot in commuter areas and city centres.

Limitations

Coefficient of variation 4.1%. Coefficient of variation 4.8%.
