Following ‘Brexit’, the UK leaving the EU, we analyse the effects of changes in the legal framework on EU residents and compare them with UK citizens, employing a difference-in-differences framework. The research focuses on several dependent variables, including labour supply and wages, self-employment rates, and changes in industry, using the Annual Population Survey (APS) data 2012−2022 in the UK (itself based on the Labour Force Survey (LFS)), National Insurance Number registrations, and visas issued. The evidence from our analysis on EU post-Brexit migration towards the UK, together with the observed overall increase in rates of (non-EU) net migration, shows rebalancing between EU and non-EU groups. Effects are strongest at the lower-skilled end of the labour market. However, wages for UK natives and EU migrants did not change with respect to each other, controlling for occupation, industry, and other factors.
