This EMN Policy Brief examines trends in applications for international protection and irregular movements of third-country national migrants across the EU and Norway. It focuses on the period 2012 - 2016 and – where data is available - up to August 2017. This is an update of the Policy Brief published in December 2015.

This EMN Policy Brief presents key data on the irregular movements of people across the EU external borders and within the European Union itself, whether as asylum-seekers or as migrants, over the past few years and including the first nine months of 2015.

According to preliminary data published by Frontex, the number of irregular border crossings into the European Union decreased by 27% between January and April 2025, compared to the same period in 2024. Nearly 47.000 crossings were detected during the first four months of 2025.

According to preliminary data collected by Frontex, the most significant declines in irregular border crossings were observed on the Western Balkan and Central Mediterranean routes, with a 79% and 64% decline, respectively. The Eastern Land Border and Western African routes saw the highest increases, at 192% and 100%, respectively.

Frontex revealed today that the number of detections of irregular border crossings at EU’s external borders rose by one fifth (+18%) in the first eight months of 2023 to over 232 350 and that this increase was primarily driven by the number of arrivals through the Central Mediterranean, which remains the main migratory route into the EU. 

This conference is organized by the International Organization for Migration (IOM) Vilnius office, the EMN, the Ministry of Interior and the University of Vilnius.
