The Guardian have been keeping track of the magistrate cases and convictions resulting from the recent rioting in England. Using this data I have produced the “tree map” below. For each magistrate I have grouped each offence committed and represented it as a square. The size of the square represents the number of people who have committed the offence and its colour is the mean age of the offenders. I have highlighted some of the most frequent/ serious offences in each area.
I was struck by the seriousness of the offences and the age of the perpetrators represented above. As time goes on many more squares will need to be added, but I think the plot provides a useful generalisation of the nature of the riots across England.
