We computed the numbers of jobs per region employed, directly or indirectly, in producing goods and services exported to EU regions. Indirectly affected jobs are associated with activities of which the output is sold to domestic industries, either in the same region or elsewhere in the UK, that export to the EU. We consider jobs that are directly or indirectly employed in the production of exports to the EU as jobs that are ‘at risk’. We calculated the percentages of jobs ‘at risk’ in each of the regions under two different assumptions about future trade patterns with the EU. First, the case of a total stop of exports (of goods and services) to the European Union; and second, the case where UK goods exports to the EU remain unhampered, but where the UK cannot export services to the EU, for example because it is outside the Single Market. We found that the risks vary considerably across UK regions and are disproportionately concentrated in Northern regions in the case of a total stop of exports to the EU, and in London and southern areas of the UK in the simulated case where the UK cannot export services to the EU.
