The Government are conducting pilots to test data matching of the electoral registers against various national datasets in 22 pilot sites. The pilots are still live and will continue to run until 30 November. The Electoral Commission will conduct an independent evaluation of the pilots which will be completed and published in March 2012. The Government will also undertake their own evaluation which will consider both the process of data matching and the potential impact it may have on the completeness and accuracy of the electoral registers.
