|Prime minister||Annual average||Annual minimum|
From: House building, permanent dwellings completed in the UK
I have allocated split years to the previous administration. That's not accurate, but it doesn't make a lot of difference to the results. Quarterly figures are available from the same source.
|Prime minister||Mines closed|
From: NCB Collieries in England
The NMRS has done an amazing job collating this data but it's clearly a difficult job. From the statistical point of view, though, it's a bit dodgy. There are big mines, little mines, merged mines, reopened mines, etc. So counting the number of "mines closed" isn't particularly easy or even necessarily meaningful. Nobody has checked my calculations so these should only be taken as approximations.
