“GDP is increasingly a poor measure of prosperity. It is not even a reliable gauge of production” – The Economist
There’s a bit of a story happening around Scotland’s oil trade since Wings Over Scotland highlighted an otherwise completely unreported change in the way the UK measures how much oil it trades with the world and where in the UK it comes from.
The story stems from the way that the UK calculates its balance of trade with the rest of the world and specifically how it then decides which region of the UK is responsible for that trade. To do this, the UK is split into 12 regions based on the Government Office Regions of England plus Scotland, Wales and Northern Ireland. (These boundaries are also used by Eurostat for their NUTS 1 statistics)
There’s another “region” of the UK not displayed on the map. Not all trade can be firmly allocated to a single region and not all trade can be allocated to a region at all. This is the “Unknown Regions” of the UK. Most prominent amongst this kind of trade, at least within Scottish political circles, is trade generated by offshore activities.
There are many different ways one could approach this allocation – the methodology – and the way you do it can result in very different results. Now, if you’re the UK and are looking at UK stats these figures don’t really matter so much but they do become very relevant if you’re looking at one part of the UK and what its economy might look like if it decided to, say, discuss holding a vote for independence. Suddenly, even UK government departments start getting very interested in Scottish trade.
The particular story here concerns a change in the trade methodology around offshore oil in Scotland waters. Particularly, oil which is exported out of the UK directly from the rigs without it ever touching the UK land boundaries. Previously, much of this oil has been allocated to the Unknown Region but the change now meant that it would be allocated to Scotland. This has led to an increase in the recorded value of Scottish minerals exports for 2015 from £588 million to £6,825 million. Quite a substantial jump and one which has spread around social media. Time for a wee breakdown of what it means and take the chance to clear up a few misunderstandings I’ve seen along the way.
(This is a complex topic, after all)
