The UK has experienced high levels of in-migration from all parts of the world over several decades. This Research Note presents new estimates of trade union membership among migrants in the UK. Levels of membership among migrants are lower than those employees who were born in the UK, although levels rise as time spent in the UK increases. Low levels of membership are particularly apparent among migrants from A8 and A2 countries, for whom union membership is approximately a third of the UK average.
