The IUC is a bespoke geodemographic classification that describes how people living in different parts of Great Britain interact with the Internet. It provides aggregate population profiles of Internet use and engagement at the Lower Super Output Area (LSOA) and Data Zone (DZ) level (2011 Census Geography). It has been developed in order to update and expand to the previous (2014) IUC and as such includes wider and more comprehensive data, built from a range of consumer, survey and open data collected by the CDRC.

Quality, Representation and Bias

For full details and evaluation of inputs, there is an accompanying published peer reviewed journal article. Data used in the classification were sourced from consumer purchasing records, surveys, and open data (e.g., broadband speeds from Ofcom). Small Area Estimation was used to extrapolate from representative surveys to the national extent. Consumer data including in the classification have representation that reflects the overarching customer distribution. Internal and external evaluations were conducted on the created typology, including linking the IUC to Census response rates, demonstrating its utility in identifying disparities in online engagement and informing targeted interventions.
