There are major problems with Chris Giles’ piece “Britain’s Regional Divide is Smaller than it First Appears”, Financial Times 9 May 2019.2
Chris Giles states that the evidence on regional inequality is much more complicated than often presented and he proceeds to argue that the UK regional inequality measures are somewhat distorted or even illusory due to “…the unique way the UK defines its administrative boundaries for international comparisons…”. He then compares London, Reading, Milton Keynes and the Wirral – and on this basis suggests that the gap between the highest and lowest urban areas in the UK is largely typical of other countries. He also compares Camden and The City of London with Torbay to argue that household income is a better and more equal measure of regional differences than GDP per capita. On this measure UK interregional inequality is much lower than for GDP per capita.
Yet, many aspects of Chris Giles’ argument are simply not correct. There is nothing ‘unique’ about how the UK defines its administrative borders; all countries display such idiosyncrasies. This is why it is essential to ensure comparability as far as possible when comparing different countries – exactly what the OECD data are designed to facilitate within individual classification or definitional schemes.
Chris Giles also jumps around between different spatial classification types, namely OECD-TL2 areas, OECD-TL3 areas, and OECD Functional Urban Area definitions. These spatial units cannot be compared in such a manner.
Finally, regional variations in household income will always be lower than regional variations in GDP per capita, so this observation tells nothing new. Household income and per capita GDP are measures designed to tell us different things. While Chris Giles may prefer the former most economists working in the fields or urban and regional economics and economic geography consider the latter to be a much better measure of regional productivity and prosperity, the proper focus for regional policy.
Once we compare like-with-like across 30 countries and for 28 different measures of interregional inequality, amongst the advanced economies which the UK considers as its peer group, the UK emerges as the most unbalanced and unequal country across the largest range of indicators, including disposable income.3 Indeed, apart from five countries at much earlier stages of development, namely Chile, Mexico, Turkey, Bulgaria and Romania, the only OECD or EU country which is more interregionally unbalanced than the UK is Slovakia. As such, the argument that UK interregional inequalities are typical of other countries is simply not correct.
In order to understand the degree to which the UK is interregionally unequal three further observations are very useful.
(a) Immediately after reunification in 1990 Germany was, not surprisingly, the most interregionally unequal advanced OECD economy. However, over three decades Germany has become more interregionally equal, while the UK has become more interregionally unequal. In terms of the ratio of the top 10% over the bottom 10% of GDP per worker levels, the UK became more interregionally unequal than Germany in 2008 and the same is true in terms of the top 20% over the bottom 20%. In terms of the top 10% over the bottom 75% of GDP per worker values, the UK became more interregionally unequal than Germany in 2004. The result of these trends is that today almost half of the UK population live in regions whose productivity (the best proxy for economic prosperity) is no better than the poorer parts of the former East Germany.
(b) Close to half of the UK population today live in regions which are poorer than the poorest US states of West Virginia and Mississippi (McCann 2016) – places which are often the focus of UK journalists aiming to articulate why people vote for President Trump.
(c) Out of the 179 NUTS3 areas within the UK, 159 areas have productivity levels below the UK average.4
Chris Giles has also tweeted5 on the subject “It’s rarely wise to rail against the conventional wisdom on regional divides in Britain. But look at some facts people…”.
This argument is also incorrect.
The longstanding conventional wisdom in the UK, and especially in many of the central institutions and think-tanks, has been that UK interregional inequality is not really important or significant in any way. The recognition that Chris Giles refers to on the part of some politicians and some economists actually represents a very recent, and still very incomplete, shift in thinking. Indeed, the conventional wisdom in many high-level circles is still that UK interregional inequality is still not a major issue. In this context the arguments put forward by Sir Angus Deaton this last week at the launch of new IFS enquiry into inequality were especially pertinent, highlighting the fact that many different indicators of UK inequality are evident interregionally.6
Chris Giles further contributes to the confusion by arguing that “There is no doubt that place has become a serious UK faultline, dividing north from south, urban from rural and cities from towns”. Yet, a careful reading of the OECD, Eurostat and ONS data7 shows that much of this recent conventional wisdom is also incorrect in that within the UK there are few, if any, major gaps in prosperity between urban and rural areas, or between cities and towns. Contrary to some of today’s popular narratives, the UK gaps between cities and towns and urban and rural areas are actually small by international standards.
In other words, the real geographical inequalities and imbalances within the UK are between regions; they are not between cities and towns or between urban areas and rural areas, and by international standards UK interregional inequality is very high. Indeed, the same IFS report referred to by Chris Giles also points out that household income today in most of the Midlands, Northern regions and Wales is equivalent to household income in the South East during the 1990s. In the case of GDP per capita the differences are even greater. I would suggest that many people are well aware that their communities are literally decades behind.
 I would like to thank Sir Paul Collier (University Oxford), Professor David Bailey (University of Birmingham), Professor Raquel Ortega-Argilés (University of Birmingham), Dr Paolo Veneri (OECD, Paris) and Ben Gardiner (Cambridge Econometrics) who all provided constructive feedback on earlier drafts of this short paper. The views advocated here reflect my own understanding of the issues.
