Immigration has been in the news a lot lately, especially with the EU referendum coming up.
So let's use the tools and data of political science to understand the topic better.
Last year, 270,000 EU citizens immigrated to the UK, and 85,000 returned to the EU. So EU net migration was around 185,000 (1). Additionally, a similar number came from outside the EU, so 330,000 in total.
That was the highest ever level of EU migration – going all the way back to when we joined the EEC in 1975. Indeed during the 1980s the trend was the other way – British workers moved overseas, particularly to Germany, as their economy was doing better than ours at that time. You might remember the TV show ‘Auf Wiedersehen Pet’. Currently our economy is doing better than many European ones so more people are coming than going. But there's no reason to think that will always be the case.
The Leave campaign claim that EU migration is putting unsustainable pressure on our public services, worsening the housing crisis, putting pressure on the NHS, on schools and on our roads. Their latest TV broadcast for instance shows a sick older lady receiving NHS treatment much faster in an imaginary hospital if we leave the EU. Are they right?
Imagine that we left the EU and banned EU immigration completely. Nobody else allowed – no footballers, no entertainers, no chefs, no businessmen, no nurses, no cleaners, nobody. And we kept that door shut for ten years. And for comparison let’s say that we stayed in the EU and immigration continues at this year’s record level (the highest ever) for the next ten years. How would that impact our population and our public services?
In terms of population, we’d end up with 1.85m fewer people living in our country after the 10 years. That sounds like a lot of people, which it is. But we’re a big country – 64.6m in total at the moment (2). So even under these very extreme assumptions the difference is only 2.8%. Less than 1 in 35.
Would you notice the difference if there were 34 instead of 35 people in your doctors’ waiting room? If there were 34 instead of 35 cars ahead of you in the traffic jam? Would your child’s education suffer in a class of 34 instead of 35? I doubt it.
And don’t forget that we’re making crazily unrealistic assumptions about how much we could reduce immigration if we left the EU. Because even the most ardent Leave campaigners don’t say that we should stop immigration altogether. They usually talk of using a points system to reach the government’s net target of 100,000 per year. So the difference in population after 10 years wouldn’t be anything like as much as 1 in 35.
Let’s say we could hit the net target of 100,000 – half from the EU and half from non-EU countries for the sake of argument. In that case, the difference in population after 10 years would be 1.35m or 1 in 49.
And don’t forget that we’re also making another very aggressive assumption – that migration will continue at the same level as last year, our highest ever. It would be more realistic to take the average of the last five years migration (3). If we do that, then the difference in our population after ten years would be only 790,000 or 1 in 82.
1 in 82.
I can’t tell the difference between a crowd of 81 and 82 people (even when they were my own wedding guests!). Can you?
So here’s the thing: however you feel about EU immigration, even under extreme assumptions the impact on our overall population just isn’t very large.
Now at this point some of you might be thinking – “This can't be right - step outside and look with your own eyes! Britain is full of foreigners! The place I grew up is like another country! How can you claim that EU immigration is not significant?”.
I live in inner London so I can sense where you might be coming from. A few things to bear in mind:
1) The overwhelming majority of immigration to the UK over the last 40 years has been from outside the EU (3). However you feel about that, it has nothing to do with our EU membership;
2) Whether you like it or not, Britain has been a multicultural country for several generations at least. You can’t tell whether somebody is an immigrant just by looking at them (sorry if this is an obvious point). You might hazard a guess at their ethnicity or race but that’s a very different thing;
3) Historically, immigrants have clustered in particular areas of the country, so your neighbourhood may not be representative of the country at large;
4) British people from all backgrounds have become much more cosmopolitan in their tastes over the last 40 years. We drink in pubs much less, but enjoy wine at home or go to restaurants and cafes a lot more. Instead of just eating British food, we enjoy flavours from all over the world. So the retail and commercial landscape of our country has changed - to reflect our changing tastes, not just because of new arrivals.
“But wait! What when Turkey, Montenegro and Albania join the EU? We’ll be swamped!”
No we won’t.
Mainly because Turkey and Albania are nowhere near being eligible to join the EU, and Montenegro is tiny. Also don't forget there are 27 other countries in the EU to choose from if residents of those countries did fancy a change of scene.
And even if in the distant future many other countries did join and we did find ourselves swamped, Britain could leave. We’re free to leave the EU whenever we want. But if we leave and then want to rejoin, we’d need the consent of all 27 other member states. Better to stay and keep our options open than leave in fear of something that is very unlikely to happen.
And so far we’ve also not factored in the contribution that immigrants make to our country, and specifically our public finances. EU migrants contribute more in taxes than they use in public services, as they are much more likely to be of working age than the general population (4). So if we used that extra tax revenue to hire more doctors, build more schools, invest in transport and so on, we’d actually have better public services than we would without any EU immigration.
It takes time to hire and train teachers and doctors, build schools and roads, and so forth. So it’s true that a sudden influx of people into an area can put short-term pressure on services. But the fundamental reason for the issues we identified at the start – NHS pressure, oversubscribed schools, congested roads, the housing crisis – is not EU immigration.
We are now six years into a government austerity programme to attempt to balance the books. So it’s not surprising that our public services are feeling the pinch.
An ageing population and new advances in medicine put particular strain on the NHS.
For the last thirty years, we have failed by a wide margin to build enough houses in the UK. Interest rates have been at an ‘emergency’ rate of 0.5% for the last seven years. That is why house prices are so high.
And this story of decades of underinvestment is repeated for our roads and railways too.
All of these issues are home-grown. And all of those policy areas are entirely within the control of our government in Westminster. They have nothing to do with the EU and are not the fault of EU migrants.
Finally, there’s been plenty of academic research into this issue, including a summary paper just published by the London School of Economics (5).
The research shows, contrary to many tabloid headlines, that
1) Immigrants do not take a disproportionate share of jobs created by our economy;
2) There is no evidence of an overall negative impact of immigration on wages;
3) There is no evidence that EU migrants affect the labour market performance of native-born workers (i.e. make it harder for native-born workers to get promoted, get a pay rise, etc)
So it is clear from examining the evidence that fears of immigration have been blown out of all proportion by the Eurosceptic press and the Leave campaign.
But what about all that money we send the EU? Couldn't we use that to improve public services?
Yes, but it wouldn't go very far, and it would be outweighed by the economic damage from leaving.
Our net contribution to the EU was £8.5bn last year (6) which works out at 36 pence per person per day. That is a drop in the ocean compared to our annual NHS budget of £116.4bn (7).
And if you’re trying to work out the impact of leaving the EU on our public services, you can’t just look at our net contribution. You also need to consider the effect that leaving would have on the size of our economy, and hence the tax revenue the government can generate.
Seven highly respected independent economic organisations have tried to work this out (8). And all seven of them have reached the same conclusion: that the economic damage caused by Brexit would more than offset the saving from our EU contribution.
The best estimate suggests that the government would have between £20bn and £40bn less to spend on public services than if we remained in the EU (9). So our public services wouldn't be better if we left the EU - they would be much worse.
So if we left the EU to ‘take control of immigration’, and then reduced it as discussed above, we’d still have all the same problems we have today – the housing crisis, an overstretched NHS, oversubscribed schools, heavy traffic, etc.
