Scottish devolution a ‘disaster’? Let’s look at the data

The Conversation

When the UK prime minister, Boris Johnson, recently told a group of MPs that devolution in Scotland has been a “disaster” he raised an interesting question. Has handing greater powers to the Scottish government been a bad move, and, if so, for whom?

Johnson’s comments have been taken as a boon for the independence movement, including among members of the SNP, which is in government in Scotland. Even before he said it, polling put support for Scottish independence at its highest ever – at about 60%. And looking at the data, it does appear that devolution has been associated with a period of good economic performance.

The good

If we look at the Scottish workforce, we find that Scottish employees appear somewhat better off than their English counterparts. In 1999, before devolution, average (median) weekly wages for full-time Scottish employees were more than 5% lower than their English counterparts. By 2019, that gap had halved. In 2020 (where caution is needed in interpreting the figures due to the pandemic) they are actually earning more, on average than their English counterparts.

This comparison actually rather flatters England, because the cost of living is higher in England. If we compare instead the north-west (a region with a larger population than Scotland), where prices are similar, we see that median full-time wages were on a par in 1999 but by 2019 Scottish median wages were nearly 5% higher. This has been concentrated at the lower end of the income spectrum where improvements arguably are needed most.

A similar story can be told in terms of productivity, where growth in Scotland has been significantly more rapid than in England (increasing from 1.3% below that in North West England to a remarkable 6.5% above) in the two decades since devolution.

The bad

However, in contrast, in terms of life expectancy, Scotland’s performance has been mediocre. Scots can expect to live fewer years than the English, Welsh or Northern Irish. Since the pre-devolution period, life expectancy for Scottish men increased at a broadly similar rate to that in the other UK nations (by roughly 4½ years, which is slightly less than England but slightly more than Wales). Life expectancy for Scottish women has fallen somewhat further behind that in England.

However, this data can be somewhat deceptive. It’s extremely difficult to disentangle historical lifestyle factors from the impacts of policy. Certain behaviours known to reduce lifespan are more common in Scotland: we know, for example, that Scots are more likely to smoke than the English.

And comparing Scotland to England as a whole is rather misleading since London is driving a significant chunk of the improvements in England. We have data on regional life expectancy going back to 2001-3. Scottish life expectancy has increased by 2.28 years for women and 3.66 years for men during that period and the commensurate figures for England are 2.67 and 3.56 respectively. However, life expectancy in London has increased by 3.9 years for women and a remarkable 4.9 years for men in less than two decades. The remaining regions of England look very similar to Scotland.

Another area where one can legitimately criticise the SNP Holyrood administration is on education. Scotland spends considerably more (per child) on pre-tertiary education than any region in England (£6,191 per child against £5,216 in England – and the latter includes the London weighting). Yet it appears to get poor results. Direct comparisons are difficult because of different systems – but Scotland’s scores in international comparisons are below England’s.

The verdict

Scotland’s government is far from perfect, and there are clear areas for improvement. However, that is a failure of a specific administration and not a failure of devolution. Indeed, it is far from clear that Westminster would do any better.

What evidence we have, then, the worst you can say about devolution when it comes to these factors is that the evidence is mixed. And, generally, it looks good. Indeed, to the extent that the health disparities evident in Scotland represent a legacy of decades of diet, alcohol consumption and jobs in defunct sectors such as mining that carried particular health risks, it is still too early to assess the impact of devolved government in tackling deep-seated health problems.

In economic terms, far from being a disaster, Scotland has performed reasonably well since it was handed greater powers. Devolution, we would argue, is only a “disaster” from the perspective of those such as the prime minister, who see the success of a SNP government in Holyrood (having been in power since 2007) as a threat to Scotland remaining in the UK.

If the economic performance of Scotland relative to the English regions at least is anything to go by, then the UK needs more devolution and not less.
