Eurostat: Enforcement of immigration legislation statistics

Eurostat presents indicators on the enforcement of immigration legislation. It provides statistics on: non-European Union citizens who were refused entry at the external borders of the EU-28; non-EU citizens who were illegally present on the territory of an EU Member State; and non-EU citizens who were ordered to leave the territory of an EU Member State.

Each of these indicators can be regarded as an official record of persons subject to the enforcement of EU immigration legislation, providing a general overview of the outcomes of territorial surveillance and control procedures.
