Key findings

  • The local government registers in Great Britain were 83% complete, and the parliamentary registers were 85% complete
  • The study found that the main drivers of lower completeness are being younger, recent home movement and whether someone rents their home from a private landlord. These drivers of lower registration are in line with our findings in previous accuracy and completeness studies
  • Other factors associated with lower rates of registration include ethnicity, nationality and attitudes towards registration and voting


The parliamentary registers for Great Britain were found to be 85% complete, and the local government registers 83% complete overall.

Except where stated, the figures outlined relate to the local government registers as these include the larger proportion of the electorate. Where comparisons made in the text are not statistically significant this is acknowledged.
