Methodology

Area Score (0–100)

Scores are derived from the official English Indices of Deprivation 2025 (MHCLG), published under the Open Government Licence v3.0. We take the LSOA-level domain scores (never ranks or deciles, which cannot be averaged) and aggregate them to neighbourhood (MSOA) level using population weighting (ONS mid-2022 denominators):

MSOA score = Σ(LSOA score × LSOA population) ÷ Σ(LSOA population)

Each aggregated score is then converted to a 0–100 scale by national percentile, inverted so that 100 = least deprived in England and 0 = most deprived. The same transform produces seven themed sub-scores.

Compare My Postcode relabels the official deprivation domains with neutral theme names. Provenance is unchanged:

This is relative, not absolute. Per MHCLG, there is no threshold above which an area "is deprived". An area scoring 80 is not "twice as good" as one scoring 40.

House prices

House-price figures come from HM Land Registry Price Paid Data. We keep standard full-market-value sales (PPD category A) of residential property (detached, semi-detached, terraced, flat) and place each sale into a neighbourhood by postcode. For each neighbourhood we compute the median price over the trailing 12 months to the latest complete month, sale volumes, and 1/5/10-year changes against like-for-like 12-month windows, plus a 20-year annual median series.

Because Land Registry registers sales with a lag of several months, the most recent months are incomplete, so we end every window three months before the latest data to avoid a biased median. Where a neighbourhood has fewer than 10 sales overall (or 5 for a property type) in the window, the figure is suppressed and we show the wider local-authority figure instead — we never interpolate or invent a value. Every figure is shown with its sample size.

We cross-check our local-authority medians against the official UK House Price Index each month and review any large divergences (these usually reflect a shift in the mix of properties sold, which the mix-adjusted UK HPI controls for and a raw median does not).

Affordability-adjusted Score

This is a derived measure that deliberately brings the two datasets together — the one place on the site where we do. For each neighbourhood we take its Area Score as a national percentile (how un-deprived it is, 0–100) and an affordability percentile built from its median house price (the cheapest neighbourhood in England scores 100, the most expensive 0). We combine them with a geometric mean and then re-rank the result into a national 0–100 percentile:

Affordability-adjusted Score = national percentile of √(Area Score × Affordability)

The geometric mean is deliberate: it rewards areas that score well on both dimensions and penalises being weak on either, so the top of the ranking is genuinely "less-deprived and cheaper than average", not just one or the other. The best value areas page ranks England by this score.

Two honest limits. "Affordable" here means cheap in national terms — it does not account for local earnings, so it is not a true affordability (price-to-income) measure; that needs income data we don't yet include. And because it uses a raw median, an area can look cheap simply because more of its sales are flats or smaller homes. Neighbourhoods with too few recent sales to price are excluded. This is orientation, not investment or financial advice. We never fold this score back into the Area Score itself, which remains a pure deprivation measure.
