How odd.
Just looked at the chart linked to, and I assume, as I see no key, that the grey section is all the other causes of lesser percentages.
I don't know enough about the ONS, but of late I've been questioning their stance anyway, due to the recently published data regarding wage rises against inflation, and employment levels. Seems to me that they are aiming to muddy the waters with purposefully vague terminology, or at least published in the media with that interpretation.
The part I questioned previously could be questioned as to whether the vague description does include accidental injury (i.e. including motoring and industrial 'accidents'*, but almost disguised by bracketing it in with suicide and poisoning, and put in that sequence. I really cannot believe that suicide is the biggest killer of my own subgroup.
My issue with the other stats I refer to above, is the use of 'average' taking the data out of context and misleading the reader. "The average wage is rising faster than inflation": how to define that? Average shows no interest in allowing for disparity, let alone income- wages seemingly only being counted, which presumably discounts the unwaged. Bankers bonuses removed, the stats showed that the rise was less, but more awards for the upper echelons are based on crazy wages and other benefits now, so we can see that the stats are incredibly skewed.
Does this follow with all ONS data? Are they just a flunky wing of the incumbent government?
BTW, I am not questioning you, Joe, just the system! Try not to let the little gits and Gove get you down...
* 'Accidents' of course being a poor word to describe what is usually being referred to; generally with bias or intention.
