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).

A small error occurred in Tables 1, 2, 5, 8, 10 and 11 (labelled Tables 1 to 6 in the previous version of this data) due to the patient population being incorrect and updates to the survival estimates used to produce the 2007 to 2011 reference tables. We have corrected this error. You can see all previous versions of this data on the previous versions page. We apologise for any inconvenience.
