Oops!

.. I am fairly sure that one in five of my friends hasn't hunted in the last year.

Part of the reason these figures look odd is that the report is focused, quite intentionally, on the group most directly affected by the ban, not on the general population. This was done to meet its remit, namely to assess "THE EFFECTS OF HUNTING WITH DOGS ON THE SOCIAL AND CULTURAL LIFE OF THE COUNTRYSIDE IN ENGLAND AND WALES".

But the figure of 59% is being presented as if it represents the whole population.
