"Figure 11: Number of deaths from drug misuse by registration year and occurrence year, 1993 to 2014","" "Wales","" "","" "Notes","1. Cause of death was defined using the International Classification of Diseases, Ninth Revision (ICD-9) for the years 1993 to 2000 and Tenth Revision (ICD-10) from 2001 onwards. More details can be found in the Quality and Methodology Information. 2. Figures only include deaths that were registered by 31 December 2015. Due to the length of time it takes to complete a coroner’s inquest, it can take months or even years for a drug-related death to be registered, so figures for deaths occurring in 2014 will be an underestimate. 3. Deaths of persons usually resident in Wales, based on boundaries as of May 2016.
