The EU has 27 member states
All European countries that respect the EU's democratic values and human rights and freedoms can apply to join the EU. Today, 27 European countries are members of the EU. Sweden joined the EU in 1995 after a referendum.
From 6 to 27 countries
The EU started as an organisation for cooperation between six countries in Western Europe during the post-war period. Over time, the Union has grown and today it has 27 member states. The EU's greatest enlargement took place in 2004, when ten countries in Eastern Europe became members. The UK left the Union on 31 January 2020.

All EU countries can trade freely with each other within the single market. The countries also cooperate on climate and environmental policy, transport, foreign and security policy, judicial matters and migration.
The EU's policy areas
The common currency – the euro
20 of the EU's member states are part of the euro cooperation and use the euro as their common currency. The euro was created to simplify trade between the countries, and any country wishing to introduce the euro must first meet a number of economic criteria. Sweden's politicians have not introduced the euro in Sweden. This is because a majority of voters voted against introduction of the euro in a referendum in 2003.
EU countries that have introduced the euro
The 20 EU countries that have gone over to using the euro as their currency are Austria, Belgium, Croatia, Cyprus, Estonia, Finland, France, Germany, Greece, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, the Netherlands, Portugal, Slovakia, Slovenia and Spain.
Schengen facilitates free movement
The overall goal of Schengen cooperation is to strengthen free movement of goods, services, people and capital across borders.
Sweden belongs to the Schengen area, which comprises 23 EU countries plus Iceland, Liechtenstein, Norway and Switzerland. Border controls have been abolished within Schengen. This means that passport controls between the Schengen countries have been removed – the idea is that it should be easy for everyone to travel across borders. Instead, the countries belonging to Schengen have border controls with countries that are not part of the cooperation. A Schengen country can temporarily reintroduce passport controls for reasons of national security.
Freedom of movement
Countries in the Schengen area
The countries belonging to the Schengen area are Austria, Belgium, Croatia, the Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Italy, Latvia, Lithuania, Luxembourg, Malta, the Netherlands, Poland, Portugal, Slovakia, Slovenia, Spain and Sweden. Iceland, Liechtenstein, Norway and Switzerland all belong to the Schengen area through special agreements.
Trade agreements with neighbouring countries
The EU cooperates with Norway, Iceland and Liechtenstein, which all belong to the European Economic Area (EEA). The EEA Agreement involves extensive cooperation and means that these countries are included in the EU single market. Switzerland also has a similar agreement with the EU.
