Participation in the 2005 general election by adults with intellectual disabilities

International and UK legislation confirms and supports the right of adults with intellectual disabilities (ID) to vote. It is widely accepted, although not previously empirically confirmed, that citizens with ID are under-represented at the polls.

To document the extent of their under-representation at the polls, the names and addresses of adults using services for people with ID in one county in the UK, were compared with the marked electoral register following the 2005 general election. Adults using services for people with ID were identified either as un-registered, as registered to vote but not having voted, or as having voted.

Adults with ID living in the county at the time of 2005 general election were substantially under-represented at the polls. Compared with the general population, proportionally fewer of them were registered to vote, and proportionally fewer of them voted. Compared with adults living in private homes, those in supported accommodation were more likely to be registered to vote, but less likely to use their vote. The most significant predictor of participation was living in a household with at least one other active voter.

The importance of the close proximity of an active voter is likely to be different for adults in supported accommodation compared with those living in private households. Further research is required to understand what features of these two very different types of residences are affecting voting opportunities.
