Cohesion
All roll calls · whole term, 16 Jul 2024 – 25 Sept 2026 · topic Economy & single market (model-assigned) · political groups · per month · abstentions counted
How united do the groups vote — over time, and on the votes of each committee or topic?
Cohesion over time
Agreement Index per month, from 0 (evenly split) to 1 (all voted the same). A vote counts for a bloc when at least 10 of its members and a third of its seats voted; a gap is a period with fewer than 20 votes counted.
Oct 2024 → Sept 2026; each panel highlights one series, the others faint behind it.
Dashed: a period with fewer than 20 votes counted (no value) between two that have one.

About these figures
What was counted, what was left out, and how.
- 1 257 votes considered (all roll-call votes matching the filters; scope).
- 38 of 185 decisions in the period had no final vote recorded by name (a show of hands or a count without names) and cannot be measured.
- 5 times a bloc had too few members voting on a vote (fewer than 10, or under a third of its seats) and was left out of that vote (turnout rule).
- Cohesion is the Agreement Index: 1 when every voting member took the same position, 0 when the bloc split evenly three ways (method). A bloc counts on a vote only when at least 10 of its members and a third of its seats voted; the non-attached have no group cohesion.
- Months are offered for all roll calls only, and a month needs at least 20 votes.
- Each member is counted in the group they belonged to on the day of the vote (group at the date).
- Roll calls are not a random sample: final votes on laws are recorded by name, most other roll calls because a group asked for it. A group’s line is inferred from its members’ votes; the Parliament publishes no whip.
- Methods: Cohesion (Agreement Index) v1, Final votes and all roll calls v1, Group at the date of the vote v1.
- Data as of 25 Sept 2026, 03:36 UTC (data stamp f37e5638cded, code 6d4005c55bde; what the stamp is).
