Port freight and airport passengers: 2 figures changed between vintages
Comparing our archived vintage of 2026-09-09 with 2026-09-12, the Department for Transport and the Civil Aviation Authority has restated 2 figures for periods it had already published. 17,098 values were unchanged.
Periods affected: January to March 2026.
| Place | Period | Figure | Was | Now | Change |
|---|---|---|---|---|---|
| Cairnryan (port) | January to March 2026 | freight tonnage (thousand tonnes) | 563.504 | 560.184 | -3.32 |
| Southampton (port) | January to March 2026 | freight tonnage (thousand tonnes) | 8058.89029 | 8077.74629 | +18.856 |
How this was found
Both vintages were parsed with the same code that produced the published series, and compared value by value. Only periods present in both vintages are counted: a period the newer file adds is new data, not a revision. Values whose digits were reformatted without changing were set aside — there were 0 of those.
New periods in 2026-09-12: April to June 2026.
