The linked consumer registers contain the names and addresses for adults in the UK as annual snapshots from 1997 onwards. They are compiled from reported outputs from linking public versions of the electoral roll and consumer registers (supplied by value-added resellers). The data represent a near-complete coverage of the adult population at an individual level.

The Consumer Registers empower researchers to undertake individual level research on the adult UK population. As a set of geographic datasets available for several years, they can provide detailed estimates of local population change. They are also an invaluable tool for sample design. Research at the CDRC has used this data base to create ethnicity estimations (using the CDRC ethnicity estimator names software) and also applied novel linkage analysis to produce estimations of origin- destination internal migration flows.

Our updated data licence agreements mean that these data, which are used extensively to build other service data products, are only available for access by internal users (staff or students) at UCL. Interested potential external users can contact the us via the email address listed below - access may be arranged as part of a formal academic collaboration with this data service.

It is anticipated that data will continue to be updated on an annual basis. Due to the imputation process, and with the aim towards continual improvement in the register across all years, each version of the register may be slightly different for older years as well as newer.

Quality, Representation and Bias
As the data are inputted from several different organisations, it is possible that some names and addresses are inconsistently formatted between datasets. Despite applying bespoke rigorous address matching and name matching methodologies, it is still possible that same cases may not have matched. Thus the number of unique addresses is slightly overestimated.

Addresses are recorded as address lines (in a separate table). This might make address matching to other data quite difficult as the number and composition of address lines varies by addresses, and between different versions of the data too.

In addition, it is very difficult to determine the completeness of the data. The register has near complete coverage of the adult population for every year. However, for some addresses anonymised residents are imputed where a house sale is known to have occurred but no new households were detected (roughly 6% of addresses in 2016). In addition, the occupancy of households are brought forwards by a few years where no new data are obtained for an address. Data lags occur because individuals do not volunteer data every year.
It is also possible that adults who reside in multiple addresses may have duplicate entries within the data.

Whilst the data providers have attempted to compile registers which are both as complete and accurate as possible, there are data biases that should be considered. Firstly, the electoral register is known to sufficiently under-represent the following groups: the younger age groups, the non-white British population & those in rented accommodation.

Further to this, research by the CDRC using implied ethnic groups from names identified that there was a slight over-representation of White British names. Roughly 84% of individuals were classed as White British, compared to 81% from the 2011 Census for the UK. We have also identified that areas with higher proportion of adults in rented accommodation had the greatest underrepresentation within cities.
