To build on the limited published information on levels of non-UK nationals in the UK digital tech workforce we use data from the Office for National Statistics’ (ONS) Annual Population Survey (APS). The APS is the basis for the UK government’s official statistics on the labour force .
It can tell us about the composition of the digital tech industries workforce, including the proportion of workers in digital tech industries that are UK nationals, EU nationals and non-EU nationals. Using the APS, we will also be able to show evidence on how migration has affected the nationality of the digital tech industry across its sub-sectors.
For the analysis we adopt a definition of digital-tech industries used by Tech City UK in their 2016 Tech Nation report and developed by Nesta in its 2015 Dynamic mapping of the information economy report . Below is a list of industries that fall within it. In addition to the APS, we also draw on some sector specific surveys and sources, including the 2017 Tech City UK survey, research by DueDil research and LinkedIn. They are broadly consistent with the findings from the APS and illustrate the recruitment challenges currently faced by tech companies.
