Sumario:Electoral registration in the UK is often critiqued for making it hard for voters to participate in elections. However, without a tool for a systematic, international comparison, we cannot know if the UK's system is unusually difficult. To tackle this issue, we make a methodological contribution to the comparative international study of electoral registration. Using four criteria of difficulty, we create an index of difficulty of registration by adapting an American scheme [Jansa, J. M. Motta, M. and Herrick, R. (2021) 'Finding DORI: Using Item Response Theory to Measure Difficulty of Registration in the U.S. and its Impact on Voters', American Politics Research , 50: 336–52. https://doi.org/10.1177/1532673X211055050 ] and use it to code sixty-two countries. Subsequently, we find that the UK has a difficult registration process in comparison to other democracies. We also show that even without implementing automatic registration, there are ways to improve the ease of registration.
