Accuracy and completeness of the February and March 2014 electoral registers


This is our last report that looks at the accuracy and completeness of electoral registers compiled under the household registration system, using registers from February and March 2014.

After this, the system is changing to individual electoral registration (IER). Each individual will be responsible for registering to vote, rather than one member of the household registering all those who live at a property

Our findings set out the accuracy and completeness and provide a baseline position for the overall impact on the registers as a result of the transition.


There has not been a significant change in levels of accuracy since 2010.

A separate study, published alongside this report, estimated the accuracy of the December 2010 registers to be around 89%. This study has found the February/March 2014 registers to be 86% accurate.



The local government registers were 84.7% complete.

The parliamentary registers were 85.9% complete.


These results show that the level of completeness of the registers has remained stable since our previous assessments.

The patterns of registration by socio-demographic factors are in line with previous research findings and confirm that population mobility remains the demographic variable with the strongest impact on completeness.
