Tranquillity is the quality of calm experienced in places with mainly natural features and activities, free from disturbance from man-made areas. Since seeking tranquillity is an important reason why many people visit the countryside, the presence of tranquil areas helps boost rural tourism. Since rural tourism in the UK directly supports 380,000 jobs and £13.8 billion annually to the economy, and a recent survey showed that tranquillity is the main reason why 49% of visitors go are attracted to the countryside, one can conclude that tranquillity is worth 186,200 jobs and £6.76 billion a year to the economy.
