E63010463 /East Midlands evidence profile
East Midlands evidence profile
Northampton digital planning profile
Northampton is a major, non-coastal built-up area in East Midlands. ONS records show a 2021 population of 243,883; the population expanded quickly between 2001 and 2021, while the 2015 to 2024 employment series shows modest employment growth. 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
Northampton evidence synthesis: 2021 population, Population aged 65 or over, Economic inactivity
Northampton is recorded as a major, non-coastal, working 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: 2021 population → Population aged under 25 → Population change, 2001 to 2021 → Employment change, 2015 to 2024 → 2023 median house price → House-price growth, 2001 to 2023 → Population aged 65 or over → Economic inactivity.
Furthest-to-nearest distance from the middle percentile: 2021 population → Population aged 65 or over → Economic inactivity → Population aged under 25 → Population change, 2001 to 2021 → House-price growth, 2001 to 2023 → Employment change, 2015 to 2024 → 2023 median house price.
Regional peer
2021 population: 243,883 · Derby delta -31,678 people
Northampton's 2021 population is 243,883, a highest decile result at percentile 98.1 among 936 complete England records. For a bounded comparison rather than a national average, Derby supplies the regional reference; Northampton is -31,678 people from it on the displayed scale. Treat this combination as a hypothesis about content hierarchy and service-capacity assumptions, and test it through task-frequency interviews and observed completion data. The responsible interpretation stops short of intent: population size does not establish addressable demand.
Classification peer
Population aged 65 or over: 14.3% · Crawley (Crawley) delta +1.2 pp
Northampton's population aged 65 or over is 14.3%, a lowest decile result at percentile 8.8 among 936 complete England records. The same-source classification check uses Crawley (Crawley), classified as Nearer - Higher deprivation - Working. The Northampton-minus-Crawley (Crawley) delta on this metric is +1.2 pp. This evidence can narrow a discovery question around readability, keyboard access and assisted alternatives, while inclusive usability sessions and accessibility conformance checks supplies the user-level check the aggregate data cannot provide. No user or market conclusion follows automatically; an age-group share does not determine digital ability.
National peer
Economic inactivity: 32.9% · Reading delta -0.6 pp
At 32.9%, economic inactivity places Northampton in the lowest decile and at percentile 8.8 of the reviewed distribution. For a bounded comparison rather than a national average, Reading supplies the national reference; Northampton is -0.6 pp from it on the displayed scale. Use the contrast to prioritise research into assisted, accessible and non-digital completion routes. A decision should wait for accessibility testing across real tasks and support-channel evidence. The boundary is important: an aggregate inactivity rate cannot describe an individual visitor.
The distinctive metrics are not interchangeable: 2021 population, population aged 65 or over, economic inactivity each raise a different planning question when read beside Derby, Crawley (Crawley), Reading. For Northampton, 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: 243,883 people in 2021
Northampton's recorded population changed from 193,392 in 2001 to 243,883 in 2021 (+26.1%). 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: 14.3% aged 65 or over
The 2021 age-group series records 49,821 people aged 0 to 15, 27,490 aged 16 to 24, 131,728 aged 25 to 64 and 34,899 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: 32.9% economically inactive
ONS records economic inactivity at 32.9%. The published composition includes 17% retired, 3.5% long-term sick or disabled, 5.1% students and 4.2% looking after home or family. These categories support inclusive task design; they do not identify individual users or purchasing intent.
Economic context: £250,000 median house price in 2023
The median house-price series moved from £81,998 in 2001 to £245,000 in 2021 and £250,000 in 2023, a published change of +204.9%. 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
What evidence would show that the 2021 population contrast between Northampton and Derby should alter content hierarchy and service-capacity assumptions, rather than remain background context?
Evidence basis: 243,883, highest decile, with Northampton minus the regional peer equal to -31,678 people. Validation route: task-frequency interviews and observed completion data.
- 02
What evidence would show that the population aged 65 or over contrast between Northampton and Crawley (Crawley) should alter readability, keyboard access and assisted alternatives, rather than remain background context?
This question is traceable to population aged 65 or over at percentile 8.8 and a +1.2 pp profile-minus-peer difference, not to inferred local behaviour.
- 03
Which real user task would justify changing assisted, accessible and non-digital completion routes after seeing Northampton's economic inactivity position and its -0.6 pp difference from Reading?
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 Northampton's major, non-coastal, working built-up area, nearer to a major town or city classification, how should 2021 population, population aged 65 or over, 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—Derby, Crawley (Crawley), Reading—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
Separate employer and customer journeys
Northampton is classified as a working town. A useful website brief should separate recruitment, procurement and customer tasks, then give each journey its own proof, contact route and success measure instead of forcing every visitor through one generic enquiry page.
- 02
Differentiate from the nearby major centre
Northampton 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
Support quick comparison without hiding detail
31.7% of the recorded 2021 age-group total is under 25. Lead with concise task summaries and responsive performance, while keeping fees, eligibility, privacy and next steps available in the same journey rather than behind a social-only channel.
- 04
Prepare the content model for change
Northampton recorded +26.1% population change from 2001 to 2021 and +9.4% 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 E63010463. 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 Northampton.
Mosalio does not claim an office, staff member, customer, or physical-delivery presence in Northampton.

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.
