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

The Perceptions of Electoral Integrity-Mexico (PEI-Mexico) is based on an expert survey comparing the quality of elections in the June 2016 gubernatorial contests and the 2015 provincial contests. Data was collected in 31 states of the Mexican Republic which held gubernatorial elections and state legislative elections. About 1320 experts on Mexican elections were contacted, generating 502 responses, reflecting a response rate of around 36%. The study was conducted by the Electoral Integrity Project. The Principle Investigators are Pippa Norris, Ferran Martinez i Coma, Alessandro Nai and Max Gromping, based at the University of Harvard and Sydney, with the assistance of Irma Mendez de Hoyos and Nicolas Loza Otero from FLACSO-Mexico.
