Parliaments: seats and where parties stand

Seats held by each party in the three elected bodies Tally covers, and where the Chapel Hill Expert Survey, an academic survey of political scientists, places those parties. Tally does not place or rate parties itself and adds no totals by bloc.

Where parties stand, according to experts

The Chapel Hill Expert Survey (CHES) asks political scientists in each country to place every significant party on several scales from 0 to 10. Its 2024 wave (fieldwork October–November 2024) rated 14 Spanish parties, 13 of which hold seats here, with 14–16 experts each (4–5 on decentralisation). The dot is the experts' average; the line shows the spread of their answers (one standard deviation either side) on the general left–right scale. These are the experts' judgements in 2024, not the parties' own or voters' views, and parties may have moved since. One left–right line hides a lot, so the other scales are available too.

Which rating applies: in the Congress, each parliamentary group is shown with CHES's rating for the party that leads it (the Socialist group includes the PSC's deputies; the Sumar group includes Izquierda Unida, rated on its own, and the Comuns). In the Parliament of Catalonia a party is shown only if CHES rates that same party organisation: PP and Vox in Catalonia are branches of the national parties; the PSC and the Comuns are separate parties and are not rated. CHES rates national parties only, so town-council lists are not placed, even those linked to a national party.
