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 2022 edition of our workbook. In Tables 9 and 10, infant mortality rates and neonatal mortality rates were incorrect. This was caused by human error and has been corrected. In Table 12, mortality rates for infants and neonates born inside a marriage or civil partnership were incorrect. This was caused by human error and has been corrected. We apologise for these errors.

Important notes and usage information

Guidance on the circumstances in which disclosure control for birth and death statistics is required is available.
