  "methodology": "Postcode sectors (e.g. N10 3) compared on estimated \u00a3/m\u00b2 of floor space. A pair is only called a 'twin' when the two sectors share the dominant property type, build era (\u00b130y), good-school catchment provision, station access, deprivation/tenure, education, age and home size, so the price gap reflects a name premium, not a different kind of area. Estimates, not valuations; aggregated to sector, never address-level.",
