Answer :
Of the 27 EU member states, 25 are part of the Schengen Area. Bulgaria and Romania, the newest members having joined on 31 March 2024, only have air and maritime borders open, with land border controls remaining in place pending agreement to lift them. The only EU member states that are not part of the Schengen Area are Cyprus and Ireland. Cyprus is legally obliged to join in the future, while Ireland maintains an opt-out and operates its own visa policy.
In addition to the member states of the European Union, all member states of the European Free Trade Association, namely Iceland, Liechtenstein, Norway and Switzerland, have signed association agreements with the EU to be part of the Schengen Area. Moreover, four microstates – Andorra, Monaco, San Marino and Vatican City – are de facto members of the Schengen Area due to their size and impossibility of maintaining active border controls.[2]
The Schengen Area has a population of more than 450 million people and an area of 4,595,131 square kilometres (1,774,190 sq mi). About 1.7 million people commute to work across an internal European border each day, and in some regions these people constitute up to a third of the workforce. In 2015, there were 1.3 billion crossings of Schengen borders in total. Fifty-seven million crossings were due to transport of goods by road, with a value of €2.8 trillion.[3][4][5] The decrease in the cost of trade due to Schengen varies from 0.42% to 1.59% depending on geography, trade partners, and other factors. Countries outside of the Schengen Area also benefit.[6] States in the Schengen Area have strengthened border controls with non-Schengen countries.[7]
