Electoral register data

The Commission undertakes the collection and analysis of data relating to electoral registration to allow us to support Electoral Registration Officers (EROs) in delivering high-quality services. This data and analysis also informs our understanding of the effectiveness of the system of registration, and ensures we are able to make evidence based recommendations for future changes to the system.

To see the latest findings see our Analysis of the December 2016 electoral registers in the United Kingdom (PDF) and the 2016 electoral registration data (XLS).

To access historic reports and data, see our Research report library.
