Book excerpt: "A short, sharp and compelling book." The Observer At a time when immigration has once again become a deeply contentious political issue, Jonathan Portes provides some much-needed clarity, taking on misinformation and inaccurate reporting to reveal the true economic and social impact of immigration to the UK. This important book covers a short history of immigration to the UK, uses the latest research and data to summarise how it is financially beneficial to the economy, considers it′s positive effects on contemporary society, and provides straightforward answers to commonly asked questions such as: does immigration push down wages? Does it reduce job opportunities for those born in the UK? And what impact does it have on the NHS and other public services? Portes then proposes what we should do about immigration, defining what a post-Brexit system should look like, and outlining what, if anything, we should do to promote integration further.
