Provides files to download data as it existed for this dataset on previous dates.

Statistics are most often revised for 1 of 2 reasons:

  1. For certain statistics initial estimates are released with the expectation that these may be revised and updated as further data becomes available.
  2. Revisions may also be made when methods or systems are changed.

These types of planned revisions should not be confused with errors in released statistics, which are genuine mistakes. Such mistakes occur rarely and, when they do happen, corrections are made in a timely manner, announced and clearly explained to users in line with the Code of Practice for Official Statistics (Principle 2, Practice 7).

Correction See correction

We have corrected two errors in the Index of Production time series dataset due to a processing error. The previous version was incorrect because it had:

  1. Incorrect Gross Value Added Weights (GVA). These were not updated to be consistent with the Blue Book 2025 GVA weights and still displayed Blue Book 2024 GVA weights. All calculations which require GVA weights are not impacted as latest weights have been used in these calculations. Therefore no estimates are impacted.

  2. Incorrect monthly IoP data from 1948 to 1968. These were not rebased to a 2023=100 basis and were still displayed a 2022=100 basis as per the previous monthly publication. Please note periods after 1968 are not impacted and the annual and quarterly data are correct.

We apologise for any inconvenience caused.
