What the numbers reveal.
One dataset, many angles — who sits where, how much the Parliament votes, what it votes on, how unified members are, and who actually turns up. Every chart is built from the figures on this site.
Who sits in the Parliament?
The European Parliament is split across political groups — no single one holds a majority, so almost everything is built through coalitions.
How much does it vote?
Roll-call votes recorded each calendar year. The bar is every recorded vote; the small number below is the final adoptions.
What does it vote on?
The most active policy areas by number of roll-call votes. Tap any bar to explore the votes and how each country lined up.
How often do MEPs break ranks?
For most members, almost never. 534 vote with their political group at least 90% of the time; only 5 do so less than half the time. Group discipline is the rule, not the exception.
Each column groups MEPs by how often they voted with their political group's majority.
And how often do they turn up?
The same MEPs, grouped by the share of roll-call votes where they recorded a position. Most cluster high — but the tail of low attendance is longer than for loyalty.
Each column groups MEPs by their attendance — the share of roll-call votes where they cast a position.
Which countries show up most?
Average share of roll-call votes where a country's MEPs recorded a position. Tap any bar for the full national delegation.
Do national delegations stick together?
How often a country's MEPs vote the same way as their own national delegation's majority — a different question from loyalty to the European group.
Showing up vs. falling in line.
Attendance and group loyalty are different things — a delegation can be present at almost every vote yet still diverge from its European groups, or the reverse.
Each bubble is a national delegation; size reflects how many MEPs it sends. The dashed lines are the medians — hover any bubble to meet the delegation behind it.
