Top ten 'sweariest' places in Britain

Here you will find a list of the 'sweariest' towns in Britain. This research carried out by scientists at the Centre for Advanced Spatial Analysis (Casa) at UCL lists the ten 'sweariest' towns in Britain - and also the five least sweary, including higher class places like Oxford and Westminster. Could this be a direct result of better education in the richer areas of Britain in contrast with that of the North? Or is it just down to culture?
