Data reported on a monthly basis by Member States and Schengen Associated Countries on detections of illegal border-crossings on entry between border crossing points (BCPs) of the external borders of the Member States of the EU and Schengen Associated Countries; and aggregated by routes.

Routes: Western African route; Western Mediterranean route; Central Mediterranean route; Apulia and Calabria route; Circular route from Albania to Greece; Western Balkan route; Eastern Mediterranean route; Eastern Borders route.

Data for the last month available are sourced from Frontex on-going Joint Operations. They do not represent official Member States' or Schengen Associated Countries' data and only refer to the data collected within the operational areas. Member States’ official monthly data covering the entire external borders are usually available one month after the end of the reporting period.

Frontex regularly publishes updates provided by Member States and Schengen Associated Countries. The data refer to detections of illegal border-crossing rather than the number of persons; as the same person may cross the external border several times. However; there is currently no EU system in place capable of tracing each person’s movements following an illegal border-crossing. Therefore; it is not possible to establish the precise number of persons who have illegally crossed the external border.
