This dataset by the Electoral Integrity Project evaluates the quality of elections held around the world. Based on a rolling survey collecting the views of election experts, this research provides independent and reliable evidence to compare whether countries meet international standards of electoral integrity.
PEI-10.0 cumulative release covers 586 national parliamentary and presidential contests held worldwide in 170 countries from 1 July 2012 to 20 December 2023. For each contest, approximately 40 election experts receive an electronic invitation to fill the survey. The survey includes assessments from 5,230 election experts, with a 2023 response rate of 13%. The study presents two additive indices, collecting 47 indicators to compare elections for 2012-2022 and 62 indicators for 2023. The 2012-2022 indicators are clustered to evaluate eleven stages in the electoral cycle as well as generating an overall summary Perception of Electoral Integrity (PEI) 100-point index and comparative ranking. Starting in 2023, electoral integrity is measured through the aggregation of four concept indices (Contestation, Participation, Deliberation, and Adjudication).
Please note that for the QoG Data compilations, only three indicators are included: "Perception of Electoral Integrity Index", "Perception of Electoral Integrity Index Type" and "Electoral Integrity Rating".
