Despite arrivals dramatically dropping since the EU-Turkey deal was signed in 2016, the situation on the Greek islands remain difficult, with thousands of migrants and refugees stuck in substandards camps for many months, unable to leave for the Greek mainland.
Greek government data show that currently around 13,000 people are still hosted on the islands, with more than half in official sites and the remaining in other hosting facilities (UNHCR and other state run facilities).
UNHCR data show that around 4,100 people are currently on Lesvos, 3,500 on Chios, 2,000 on Samos, 900 on Leros, 2,400 on Kos, 600 on Rhodes.
A total of 30,565 asylum seekers arrived on Greek islands from Turkey between March 20, 2016 and April 4 of this year, according to European Commission data.
In the same period, only 944 refugees and migrants were returned to Turkey in keeping with the EU-Turkey deal.
