Data on the number of visits to UK open waters for recreational purposes are from various sources.
The data for England for 2012 are from the MENE survey and, as discussed above, to estimate
the values for 2008, average values for 2009 to 2012 are used. The data for Scotland are from the Scottish Recreation Survey and the data for Wales are from the Welsh Outdoor Recreation Survey.
The data for Wales are only available for 2008 and 2011 and therefore 2011 data are assumed to be
equivalent to 2012.
