Spatia® Geodemographic Products

Spatia® geodemographic products are postcode level demographic attributes, estimated using spatial microsimulation.

The Spatia® microsimulation algorithm, developed in conjunction with leading academics, uses artificial intelligence to classify neighbourhoods from imagery, combined with ONS small area estimates and Ordnance Survey vector data to provide estimates of population and household attributes at a more granular level than the output areas provided by ONS and Statistics Scotland.

The algorithm is then validated against actual known data from surveys.

Applications of Spatia® geodemographic products include targeting marketing and advertising to specific groups, local service provision and risk analysis in financial services.


KIDS provides estimates of the proportion of the population of a postcode, at various levels of education from pre-school to university. This can help identify families with children.

KIDS also includes the distance from the postcode to the nearest educational establishment of each type. This can be used to identify student areas near university campuses.

It uses ESA satellite data, OS educational establishments, ONS data and HESA student numbers to calculate the estimates.
