The “Swing Riots” are supposed have covered all Southern England, and thus demonstrate that there was hunger in the agricultural population in all this area. The reality is that almost all the violent acts took place in Kent plus East Sussex, and also in an area composed of the south-eastern half of Wiltshire, the south-western quarter of Berkshire, and some northern parts of Hampshire (in sum, about 50 miles by 40 miles).

The machine-breaking activities were even more localized (note that in Kent, they were only in the extreme East):

We also have a map of the basic weekly wage in a number of parishes in 1832, as given in the “Rural Queries”. The most virulent events were in the regions with lowest incomes. But this does not explain why the Riots started in Kent, with a general income of 12 shillings. Note the area of the High Weald, on the boundary between Kent and Sussex, with an income of less than 12 shillings.

The great majority of the actions took place in a period of 4 months (in Wiltshire + Berkshire + Hampshire, in 20 days, in November):
