Provides files to download data as it existed for this dataset on previous dates.
Statistics are most often revised for 1 of 2 reasons:
- For certain statistics initial estimates are released with the expectation that these may be revised and updated as further data becomes available.
- 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
A correction has been made to the ‘New psychoactive substances (including “legal highs”)’ section of this statistical bulletin. In addition, statistics showing deaths involving New Psychoactive Substances (NPS) in Table 1 and Figures 4 and 5 have also been corrected. This was due to an error when a number of substances that should have been included in the NPS category were accidentally missed out (see below for more details). You can see the original data here. We apologise for any inconvenience.
