South East evidence profile
Caterham digital planning profile
Caterham is a medium, non-coastal built-up area in South East. ONS records show a 2021 population of 22,757; the population expanded quickly between 2001 and 2021, while the 2015 to 2024 employment series shows a material employment contraction. This profile turns those public observations into a reviewable website-planning brief without claiming that the figures measure searches, leads or Mosalio's physical presence.

05 / Evidence synthesis
Caterham evidence synthesis: 2023 median house price, Employment change, 2015 to 2024, Economic inactivity
Caterham is recorded as a medium, non-coastal, residential built-up area, nearer to a major town or city. This classification sets a transparent frame for the three observations below; it is not a persona, a service-area promise or proof of local search demand. Each finding pairs one distinctive percentile measure with one independently selected peer and one explicit validation route.
Eight-metric evidence matrix
The matrix shows every measure used by the peer-distance method, not only the three most distinctive values. Direction describes the published value relative to the middle percentile position; it is not a positive or negative judgement.
Highest-to-lowest percentile order: 2023 median house price → Population aged under 25 → Population change, 2001 to 2021 → 2021 population → House-price growth, 2001 to 2023 → Population aged 65 or over → Economic inactivity → Employment change, 2015 to 2024.
Furthest-to-nearest distance from the middle percentile: 2023 median house price → Employment change, 2015 to 2024 → Economic inactivity → Population aged under 25 → Population change, 2001 to 2021 → Population aged 65 or over → House-price growth, 2001 to 2023 → 2021 population.
Regional peer
2023 median house price: £447,698 · Chesham delta +£21,698
Caterham's 2023 median house price is £447,698, a highest decile result at percentile 91 among 936 complete England records. Chesham, the named regional peer from South East, differs by +£21,698 when the calculation is Caterham minus peer. Nearest complete record in South East. Use the contrast to prioritise research into pricing clarity, qualification steps and expectation setting. A decision should wait for comprehension tests using the organisation's real offer and fees. The responsible interpretation stops short of intent: a median house price is not a household affordability measure.
Classification peer
Employment change, 2015 to 2024: -12.5% · Rawdon delta -12.5 pp
Among the eight reviewed measures, employment change, 2015 to 2024 stands out for Caterham at -12.5%; its percentile position is 12.6 and its band is lower quartile. The same-source classification check uses Rawdon, classified as Nearer - Lower deprivation - Residential. The Caterham-minus-Rawdon delta on this metric is -12.5 pp. For planning, document the observation beside the separation of employer, worker and customer journeys and require journey interviews plus measured form and contact outcomes before treating the idea as an accepted requirement. It must not be over-read, because employment change does not prove commercial search intent.
National peer
Economic inactivity: 34.5% · Ashford (Spelthorne) delta +0.4 pp
The reviewed record positions Caterham at percentile 15.2 for economic inactivity; its published value is 34.5% and its band is lower quartile. For a bounded comparison rather than a national average, Ashford (Spelthorne) supplies the national reference; Caterham is +0.4 pp from it on the displayed scale. This evidence can narrow a discovery question around assisted, accessible and non-digital completion routes, while accessibility testing across real tasks and support-channel evidence supplies the user-level check the aggregate data cannot provide. Keep the inference narrow: an aggregate inactivity rate cannot describe an individual visitor.
The distinctive metrics are not interchangeable: 2023 median house price, employment change, 2015 to 2024, economic inactivity each raise a different planning question when read beside Chesham, Rawdon, Ashford (Spelthorne). For Caterham, the safe next step is therefore three small verification tasks rather than one demographic persona, locality claim or generic area-page conclusion.
06 / Evidence interpretation
Planning signals before design decisions
Population context: 22,757 people in 2021
Caterham's recorded population changed from 19,169 in 2001 to 22,757 in 2021 (+18.7%). This historical direction can inform content governance and capacity planning, but it is not a forecast and does not establish demand for a particular service.
Audience context: 17.6% aged 65 or over
The 2021 age-group series records 4,710 people aged 0 to 15, 2,019 aged 16 to 24, 12,027 aged 25 to 64 and 4,001 aged 65 or over. Small differences from the headline population reflect the published source series; percentages here use the age-group total and should guide testing questions, not stereotypes.
Activity context: 34.5% economically inactive
ONS records economic inactivity at 34.5%. The published composition includes 20.4% retired, 3.3% long-term sick or disabled, 4.2% students and 4% looking after home or family. These categories support inclusive task design; they do not identify individual users or purchasing intent.
Economic context: £447,698 median house price in 2023
The median house-price series moved from £146,750 in 2001 to £425,500 in 2021 and £447,698 in 2023, a published change of +205.1%. It is contextual evidence only—not a current affordability, revenue or customer-value estimate.
07 / Independent question set
Questions this evidence cannot answer on its own
These questions convert the profile-specific observations into falsifiable discovery work. They are not recommendations to create a service, location or page, and each needs direct user or behavioural evidence before it changes a website brief.
- 01
Where should the team record uncertainty when using Caterham's 2023 median house price value and the Chesham comparison to discuss pricing clarity, qualification steps and expectation setting?
Evidence basis: £447,698, highest decile, with Caterham minus the regional peer equal to +£21,698. Validation route: comprehension tests using the organisation's real offer and fees.
- 02
How should a prototype test the separation of employer, worker and customer journeys without assuming that Caterham's percentile 12.6 position predicts an individual user's needs?
This question is traceable to employment change, 2015 to 2024 at percentile 12.6 and a -12.5 pp profile-minus-peer difference, not to inferred local behaviour.
- 03
Where should the team record uncertainty when using Caterham's economic inactivity value and the Ashford (Spelthorne) comparison to discuss assisted, accessible and non-digital completion routes?
The prompt combines one distinctive metric with the named national comparator selected by the eight-metric method. It does not treat either record as search, lead or customer evidence.
- 04
For Caterham's medium, non-coastal, residential built-up area, nearer to a major town or city classification, how should 2023 median house price, employment change, 2015 to 2024, economic inactivity be tested as separate website hypotheses without turning the combined pattern into a claim about local demand?
Cross-check all three named comparisons—Chesham, Rawdon, Ashford (Spelthorne)—and define a user-research or behavioural measure for each question before changing navigation, page scope or conversion paths. The observations share one source but do not demonstrate causation.
08 / Practical brief
Website-planning recommendations for this evidence pattern
- 01
Make service boundaries explicit
Caterham is classified as residential. Explain delivery areas, remote or on-site conditions, response times and exclusions in visible copy. This reduces ambiguity for residents without inventing a local office or multiplying near-identical neighbourhood pages.
- 02
Differentiate from the nearby major centre
Caterham is nearer to a major town or city. Use specific offer boundaries, proof and response expectations to explain why the organisation is relevant; do not rely on a place-name heading or create a doorway that simply redirects users to a national service page.
- 03
Build a broad, task-led accessibility baseline
52.8% of the recorded 2021 age-group total is aged 25 to 64, with meaningful younger and older groups also present. Organise content by task, test keyboard and mobile use, and avoid designing around one assumed demographic persona.
- 04
Prepare the content model for change
Caterham recorded +18.7% population change from 2001 to 2021 and -12.5% employment change from 2015 to 2024. Use owned templates, update dates, accountable content roles and measurable conversion events so the site can evolve without publishing unreviewed route permutations.
09 / Method and limits
What this profile can—and cannot—support
This is a Mosalio editorial interpretation of the ONS May 2026 dataset for BUA24 code E63012578. The source periods differ by metric; values are historical, not live. The profile deliberately excludes ONS experimental visitor-to-resident fields and makes no claim about search volume, rankings, customers, a Mosalio office or physical delivery in Caterham.
Mosalio does not claim an office, staff member, customer, or physical-delivery presence in Caterham.

How this page was made: Mosalio applies one documented, deterministic transform to the validated ONS record, calculates the displayed comparisons, and renders the result from source-controlled data. It is an automated public-data resource, not individually commissioned local market research. A portfolio-level editorial-value review checks every profile's source identity, distinctive metrics, peer evidence, synthesis and planning questions before index eligibility can be enabled.
Analysis basis: Midrank percentile across all accepted England records; a higher percentile means a higher published value, not a better outcome. Root-mean-square Euclidean distance across eight clipped robust z-scores; population and 2023 house price are log-transformed before median/MAD scaling.
