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 August 2019, data for 119 national elections has been collected, based on judgments provided by more than 1500 country experts. The first comparative dataset was released in late 2018. After that, a new dataset will be released every 6 months, adding information for all national elections that happened in the interim period.
