Methodology

Vote data comes from the European Parliament's Open Data API and is licensed under CC BY 4.0. Vote titles come from the Parliament's Legislative Observatory (OEIL).

The site checks the European Parliament's Open Data API for newly published votes every 10 minutes. Titles from the Legislative Observatory and topic tags are completed about once an hour. New votes therefore appear shortly after the Parliament publishes them.

The European Parliament publishes no absences. The figure shown as “did not vote” is computed here: the MEPs with an active mandate on the day of the vote, minus those with a recorded vote (for, against or abstention). Mandate periods are taken from the Parliament; on a handover day a seat can be counted twice. Votes without any recorded individual votes show no derived figure.

A national delegation consists of all members who, in a single vote, sit in the same political group, the same country and the same national party. A delegation counts as split when it has at least two recorded votes and its strongest position is below 80% of the votes cast – its own majority is then not clear.

Absences and intended but unrecorded votes do not count. Group and national party are the members' current affiliations; a change since the vote is not traced back.

The site covers roll-call votes from 1 July 2024 (the European Parliament’s 10th term).
