Plain-English definitions for the terms you'll encounter in customer data enrichment, geodemographic classification, and AI-powered intelligence.
A method of grouping geographical areas (typically postcodes or output areas) by the demographic, socioeconomic, and behavioural characteristics of their residents. Used for customer segmentation, marketing targeting, and risk modelling.
A free, publicly available geodemographic classification produced by the Office for National Statistics (ONS) based on UK census data. Assigns each output area (the smallest census geography, ~300 households) to one of eight supergroups.
A government-produced measure of relative deprivation across small areas of England, covering income, employment, education, health, crime, housing, and living environment. Expressed as a decile rank from 1 (most deprived) to 10 (least deprived).
A geographic unit formed by the postcode district and the first digit of the postcode suffix (e.g. SW1A 1). Typically contains 2,500–3,000 residential addresses. Cogstrata operates at postcode sector level to enable precision without personal data exposure.
A geographic unit used for census statistics in England and Wales, containing approximately 400–1,200 households. Often used as the base geography for deprivation indices and health data.
The process of appending third-party data attributes to an existing customer or prospect record. In demographic enrichment, a postcode is used to append socioeconomic, behavioural, and life-stage variables to customer records.
A proprietary UK geodemographic classification system produced by CACI Ltd, anchoring segment definitions to census data. One of the two dominant legacy systems in UK customer intelligence, alongside Experian Mosaic.
A proprietary geodemographic segmentation system produced by Experian, updated on a multi-year cycle. Classifies UK households into segments based on a blend of census, credit, and consumer data.
The practice of deriving customer insight from postcode geography rather than individual personal data. This approach is inherently GDPR-compliant as it operates on aggregate area characteristics rather than identifiable records.
A software system that consolidates customer data from multiple sources into a unified customer profile. Demographic enrichment data from sources like Cogstrata is typically ingested via CDP connectors or API calls.
Data sourced from an external provider rather than collected directly from customers. Demographic enrichment data is a form of third-party data used to supplement first-party CRM records.
A statistical technique for predicting the likelihood of a customer taking a specific action (purchasing, churning, defaulting). Geodemographic attributes are commonly used as input variables in propensity models.
A geodemographic system whose core segment definitions are derived from or fixed to a specific census year. As time passes, the accuracy of census-anchored classifications degrades as the population changes.
Demographic or behavioural attributes derived through machine learning inference rather than direct measurement. Cogstrata uses AI inference to derive attributes like mortgage pressure delta and discretionary spend estimate that cannot be directly observed at the postcode level.
Cogstrata enriches your customer postcodes with 5,000+ continuously-refreshed demographic attributes. No census lag, no PII exposure, API-first.
