How this survey placed the parties
Things to keep in mind
- These are estimates. Experts placed the parties: the parties did not place themselves, and no votes are counted.
- Each survey shows one moment. The Global Party Survey asked in 2019 and CHES at the end of 2024. Parties have changed since: Reform UK was called the Brexit Party until January 2021, and Labour was led by Jeremy Corbyn in 2019 and by Keir Starmer in 2024.
- The surveys do not always agree. They asked different experts different questions, five years apart. Switch the survey to see how far a party moves: Labour, for one, sits nearer the centre on the economy in CHES than in the Global Party Survey.
- Small parties are missing. CHES places only parties from Great Britain; the Global Party Survey also places the DUP and Sinn Féin from Northern Ireland, and UKIP. Neither places the SDLP, Alliance, the UUP, TUV, Your Party or Restore Britain. The Greens here are the Green Party of England and Wales: the Scottish Greens and the Green Party in Northern Ireland are separate parties.
- Two axes leave a lot out. A party can be left on one issue and right on another, and parties can be divided inside or change course with their leaders.
- The views come from Wikipedia, not the surveys. In the tooltip, the position and ideologies are how Wikipedia describes the party today.

Seats in Parliament
One dot is one seat. The parties sit from left to right by where 21 political scientists placed them on one left-right scale in 2024; parties without a place sit last.
Today's count is the house as it is: a member who changed party counts for the new one, and a substitute in office for the member they stand in for.
The blocs join the seven bands that Bolognesi, Ribeiro and Codato drew on a left-right scale from 0, the far left, to 10, the far right. Left: up to 3, the far left and the left. Centre: 3.01 to 7, from the centre-left to the centre-right. Right: above 7, the right and the far right. CHES scores only the parties of Great Britain, so the seats of the Northern Irish parties, of parties too new for the survey and of the Speakers, and in the Lords those of the crossbenchers, the bishops, the non-affiliated peers and a Conservative Independent, are not classified. Independents count as no party.

The series cover England and Wales: Scotland and Northern Ireland count crime under their own rules, so the United Kingdom has no single figure. They are the offences the police recorded, which the Home Office collects and the ONS publishes. They count only what is recorded: many crimes are never reported, and how fully the police record changed over the years.
A year counts for whoever was in office on 1 July. A term's change runs from the year before it began to its last year with data. The years above, or a name in the timeline, set the years of the chart and of every list below. The dashed line and the small change under each term are the comparison group, over the same years. BRICS, the G7 and the G20 are the average of their member countries, and count only in years when every member has data.
Ranked by the average change per year: the best first, or the highest where neither direction is better. Only years with data count. For growth that multiplies, like GDP, the average compounds; other changes are divided by the years.
