“Adds up” means you can total it over areas or convert it to other areas. See Measures and periods for why some can't be combined.
Areas and years
Request each of these with its geography and code year as geography and boundaryYear.
| Areas | Code year | Periods | Covers | Records |

| Westminster constituencies | 2024 | 2024 | UK | 650 |
Things to know
- Valid ballot papers counted in each constituency. Invalid ballot papers are excluded, as in the source field.
- Turnout is a percentage of the electorate, so it does not add across areas. A combined turnout needs the summed electorate as its denominator.
- Votes for Alliance Party. An area where the party did not stand is recorded as zero votes; this is a count, not a vote share.
- Votes for Brexit Party. An area where the party did not stand is recorded as zero votes; this is a count, not a vote share.
- Votes for Conservative. An area where the party did not stand is recorded as zero votes; this is a count, not a vote share.
- Votes for Democratic Unionist Party. An area where the party did not stand is recorded as zero votes; this is a count, not a vote share.

Corrections and improvements
These reviewed changes apply to what the API serves for this data. The publisher's source files are not changed; when a code correction applies, the served record retains the publisher's code as sourceAreaCode.
| Change | What the API serves | Applies when |

| Opt-in canonical measure-unit presentation | On the explicit canonical request, each numeric value and any publisher-supplied interval bound is multiplied by the measure's declared scale; the response names the resulting unit and calculation. | GET /v1/data/{measure-id}?units=canonical |
