One problem with the data is that they have distinct entries for United Kingdom and Northern Ireland, yet the latter is part of the former. So does United Kingdom as used in the table actually mean Great Britain, or are the NI figures actually also included in the UK figures? If they were/are distinct, non sub-setted, data sets, then they'd possibly make a useful comparison, but without that extra info it is impossible to interpret those numbers.
