The number of people usually resident in this neighbourhood. Census day was 21 March 2021, during coronavirus restrictions: students were largely counted at a parental address rather than a term-time one, and workplace populations were displaced. The census is taken once a decade, so this is now several years old. It describes the LSOA around this postcode — a neighbourhood of roughly 1,500 people — and not this address. Small counts are deliberately adjusted to protect confidentiality, so categories need not sum exactly to their totals and a difference of a person or two is noise.

Equivalised means adjusted for household size and composition on the modified-OECD scale, so a couple and a family of five can be compared. Do not read it as the cash a household receives. A modelled estimate for the financial year ending March 2023, not a measurement: ONS combine the Family Resources Survey with census and administrative data, and the method tends to pull estimates towards the average. Every figure carries a wide confidence interval — the true value could plausibly sit anywhere in it, so a difference between neighbouring areas may not be real. It is a mean, and income is skewed, so it sits above the typical household. The area is an MSOA of 2,000 to 6,000 households, several neighbourhoods rather than one street.

Counts companies whose REGISTERED OFFICE is this postcode. A registered office is not a place of business: accountants and company-formation agents register thousands of companies at a single address, so a large number here usually means one agent rather than a business district. Sole traders and ordinary partnerships are not on the register at all, so this undercounts businesses as most people use the word. Only companies with an active status on the monthly snapshot are counted; dissolved and liquidating companies are excluded. No address, company name or officer detail is stored or shown.

A modelled count, not a list of households. A neighbourhood with more homes will show a bigger number without being worse off, which is why the proportion beside it is the figure to read. A MODELLED estimate for the neighbourhood (LSOA) around this postcode for 2024, not a measurement and not a statement about any household here. England measures fuel poverty with the Low Income Low Energy Efficiency (LILEE) definition: a home rated D or worse for energy efficiency whose residual income after modelled energy costs falls below the poverty line. It is not a count of households unable to afford heating, and it is not a bill. The publisher states that small-area estimates "should only be used to look at general trends and identify areas of particularly high or low fuel poverty. They should not be used to identify trends over time within an LSOA, or to compare LSOAs with similar fuel poverty levels due to very small sample sizes and consequent instability". Scotland and Wales define fuel poverty differently and their figures are not on this scale.

Modelled annual average for the 1 km grid square containing this postcode — an estimate from Defra's national air-quality model, not a measurement taken here. It is a BACKGROUND concentration: the roadside increment is deliberately excluded, so streets beside busy roads inside this square are worse than this figure. Model methodology changes between years, so year-on-year comparisons are indicative.

Defra's published ozone metric: the modelled number of days on which the daily maximum running 8-hour concentration exceeds 120 µg/m³. It is not an annual average concentration, and Defra publish no such figure for ozone. Modelled for the 1 km square containing this postcode, not measured here, and a background estimate that excludes the roadside increment.

This is the estimated chance that a home in this 1 km square exceeds the 200 Bq/m³ radon Action Level. It is NOT a measurement of radon at this address, and no map can tell you what any individual property contains — only a test in the property itself can, over three to six months. The mapping is also deliberately precautionary: BGS class each square by the HIGHEST radon potential found anywhere within it, so most homes in a square have a lower potential than the band shown. It does not apply to basements, cellars or underground rooms at all, which should be treated as higher risk wherever they are. For a definitive assessment of a specific address, UKHSA's UKradon service sells an address report.

Whether UKHSA classify this square as radon affected

No — this square is below the Affected Area threshold

Suppressed

Yes — this square is within a radon Affected Area

Small category cells and a complementary cell are suppressed to prevent differencing.

UKHSA define a radon Affected Area as one where at least one home in a hundred is expected to exceed the Action Level. This applies that definition to the indicative 1 km band, so it inherits the same precaution: the square is classed by its worst point, and most homes inside an Affected Area are not above the Action Level. Being inside one is a reason to test, not a finding about this property.
