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).

An error was identified for birthweights and how implausible birthweights were calculated. This happened because of a technical fault when processing the data. The error affected Table 11 of the 2021 edition of this dataset (Births by parents’ characteristics: 2021). The incorrect figures have been revised in the dataset.
