Perceptions of Electoral Integrity - US 2018 (PEI_US_2018)

This data-set by the Electoral Integrity Project evaluates the integrity of the US congressional election held on 6 November 2018. Based on a survey collecting the views of US-based political scientists, this research provides independent and reliable evidence to assess whether the 2018 congresional election met international standards of electoral integrity. The survey asks respondents to evaluate how the election was conducted in each of the 50 US states plus the District of Columbia. The study collects 49 indicators to measure electoral integrity. These 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 of US states. The datasets are available for analysis at two levels: STATE-level (51 cases); and EXPERT-level (574 cases). Each dataset can be downloaded in STATA, SPSS, CSV and R formats. PEI_US_2018 compiles the responses of 574 experts, representing an overall response rate of 14%. The study is conducted by Pippa Norris, Max Grömping, and Holly Ann Garnett for the Electoral Integrity Project based at the Universities of Sydney and Harvard.
