Latest survey

The latest survery seem to be trying to place a lot of emphasis on social media sites.  When are businesses going to realise that probably a lot less than 50% of people use social media sites? 

We don't use them and most of our friends cannot be bothered with them.  Are they assuming that every one that uses a caravan uses a social media website?  My guess is that it is less than 50% of people on this forum.
