Key findings:
- Detections of non-regional transiting migrants continue to decrease following the closure of the transit corridor in March 2016
- Despite the enhanced border-control measures, some pressure on the borders persists; some migrants still manage to make their way through the Western Balkans albeit in lower numbers and with more difficulty
- Slight increase can be observed in detected illegal stayers as it becomes more difficult to leave the region
- The irregular flow of citizens of Western Balkan countries remains low and mostly contained to the southern regional borders with Greece
