While some EU member states' population are shrinking, forecast put the UK's population at 70 million in the next decades. The UK is predicted to be the most populous country in the EU by 2050. Net migration into the UK is over 300,000 a year.
"Unlike some other member states, Britain's population is already expanding. Our population is set to reach over 70 million in the next decades and we are forecast to become the most populous country in the EU by 2050. At the same time, our net migration is running at over 300,000 a year. That is not sustainable."
David Cameron, 10 November 2015
Immigration has been named by the Prime Minister as one of the key areas of EU policy in which he will seek reform.
His claims about population and immigration are correct.
The UK's population is growing. Germany's is shrinking.
The latest population projections from Eurostat contain a number of alternative scenarios, including one where no migration takes place at all. In the 'main scenario' put forward, the UK's population grows from 65 million in 2015, to 70 million in 2030 and to 77 million in 2050. By that point, it's expected to be the EU's most populous country.
Germany, on the other hand, (the EU's current most populous country) sees its population stay at about 81 million until 2020, then enter into a slow decline, falling to 75 million by 2050.
Net migration into the UK is well over 300,000 a year
Net migration—the difference between the number of people coming to live in the UK and the number leaving in a given year—stood at 330,000 in the year to March 2015, up from 312,000 the year before, according to estimates from the Office for National Statistics.
The government has said it wants to bring that down to the "tens of thousands".
It's not just EU migration that affects the likelihood of reaching this target. Immigration and emigration of UK and non-EU citizens alone would be enough to take us over this implied 100,000 target in the latest figures.
Full Fact wants to see greater accountability for public figures who mislead us—and we need your help.
Political debate in the UK is in flux right now. The UK’s exit from the European Union is approaching, we will soon have a new prime minister and potentially a general election.
We want politicians to tell the truth, and while the best politicians realise that their work should be done honestly, some aren't taking their responsibilities seriously. Both sides in the EU referendum campaign let voters down, from deceptively designed leaflets to some of the arguments made on each side. The public rightly expects more from politicians.
We want to see greater accountability for public figures who mislead. Full Fact will continue to advocate for higher standards and call out those who don't uphold them.
But we rely on the generosity of our supporters to make sure we can spot the most harmful misinformation when we most need to.
