NEGex is the first and largest comparative dataset on the use of negative campaigning in elections worldwide based on expert judgments.

Data gathering is currently under way. As of February 2020, data for 139 national elections has been collected, based on judgments provided by more than 1700 country experts. The first comparative dataset was released in late 2019. After that, a new dataset will be released every 6 months, adding information for all national elections that happened in the interim period.
