But not in London. So they left that out.
This is such a blatant conflation of correlation and causation that even Ben Goldacre—who never criticises 'public health' bad science and sometimes defends it—emerged to poke fun at it.
A red-faced Don Shenker knew exactly what he was talking about and replied...
To which Goldacre rightly responded...
As Straight Statistics points out, Alcohol Concern quite explicitly did claim causality:
Under the heading Methodological Qualifications, the new report states: “This study did not set out to establish cause and effect.” Yet the previous page asserts that nearly 10 per cent of all alcohol specific hospital admissions in England, excluding London, are directly attributable to off-licence density, “meaning availability rather than any other external factor is the cause of one in ten of such harms”.
So either Don Shenker doesn't understand that if you say something is "the cause" you are claiming causality or he is a liar. I make no judgement on that but urge you go read the rest.
