Perceptions of Electoral Integrity-UK, (PEI-UK 2.0)

This codebook describes an expert survey on Perceptions of Electoral Integrity (PEI). The original PEI survey asks experts to evaluate electoral integrity after national-level elections around the world. However, the Project has also occasionally provided data on sub-national elections. This codebook describes all variables included in the dataset release of October 2024 of the most recent subnational elections in the UK (release PEI_UK_2.0). This study is conducted by Toby S. James, Holly Ann Garnett, and Sofia Caal-Lam for the Electoral Integrity Project based at the Royal Military College of Canada, Queen’s University, and the University of East Anglia. This survey was originally designed and conducted by Pippa Norris and the Electoral Integrity Project team at the University of Sydney and Harvard University (2012-2018). The dataset is drawn from a survey of 120 expert assessments of electoral integrity across sub-national units in the United Kingdom. The elections were the elections to the Scottish Parliament on 6 May 2021, the Senedd Cymru/Welsh Parliament on 6 May 2021 and the Northern Ireland Assembly on 5 May 2022. To operationalize the concept of electoral integrity, the PEI asks experts to evaluate elections using 62 indicators, grouped into eleven categories reflecting the whole electoral cycle. Two files are released in PEI_UK 2.0: an EXPERT-level file (38 observations) and an ELECTION-level file (3 observations). Each dataset can be downloaded in the EXCEL formats.
