A couple of thoughts...
Only 1% thought that the game's "difficulty" was a deterrent to more play. This is completely counter to what we hear in the States.
Only 1% find the cost of equipment a deterrent to more play. Again, this goes against common theory here
Instead of surveying adults who are already playing the game I would like to see a survey of children asking them why they DON'T play golf. You might really learn something from that which could lead to realistic plans for attracting new players.
