The national figures, up to August 31, are surprisingly uninteresting
in this respect:
England&Wales 1356h so far (annual norm 1530)
Scotland 1102h so far (norm 1276)
N.Ireland 1145h so far (norm 1403)
Irish Republic 1173h so far (norm 1387)
Philip Eden

Which prompts the question: How do you actually arrive at a 'national'
figure? For example, if Sheffield gets on average 1230 hours, London 1494
and Bognor Regis gets 1750. how do you get to the 'norm' of 1530 for
England? And if Glasgow gets 1400 and Edinburgh 1351, where does the 'norm'
of 1276 for Scotland come from?

Just curious
