The MENE survey began in 2009 and therefore the data for annual visits are not available for 2008.
To back cast the values for 2008, a five year average from 2009 to 2013 is used. As the visitor data
relates to England only, they have been scaled up to the UK level using population alone1
. This
is required as there are not comparable data available for England, Wales, Northern Ireland and
Scotland.
