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 errors in the Smoking habits in the UK and its constituent countries dataset in Table 4a and Table 4b. The previous version contained upper confidence limits (UCL) in Table 4a that were more than 100 for 13 Local Authorities, in the data from 2020 to 2024. In Table 4b, a negative lower confidence limit (LCL) for 2019 to 2023 for the City of London has been corrected. This should have been 0.
