Re: that first link about the people on disability dying in 2011. Statistically, that doesn't really prove anything because there's nothing to compare it to. Is that a higher number than in previous years? If yes, significantly higher, marginally higher, just a teeny bit higher? It would have been far more helpful if they'd requested data for the past 10 years or so. As it is, the numbers don't really prove anything. Maybe fewer people died in 2011 than in previous years. It's impossible to say.

(note - not trying to defend the changes to the benefit scheme - I'm Canadian so don't have a horse in this race, but from a research point of view, it's rather meaningless without data from previous years)
