The highest refugee population per head in the world, and the steepest fall: from about 1.5 million to roughly 273,000 registered.
No country took more Syrians per head of population than Lebanon, and nowhere has the number fallen faster. At the peak, roughly 1.5 million Syrians were in a country of about 5.9 million people, one refugee for every four Lebanese. By January 2026 registered refugees were down to around 273,000.
UNHCR described scaling up its response to returns under force majeure conditions, which is careful language for people leaving because staying became impossible.
That figure needs a caveat, and it is an important one. UNHCR stopped registering new Syrian arrivals in Lebanon in May 2015 at the Lebanese government’s request, so registration has never captured everyone present. The real number has always been higher than the registered one.
Syrians and Lebanese have moved between the two countries for as long as there have been two countries. Syrian seasonal and construction labour was part of the Lebanese economy for decades before 2011, and Syria occupied Lebanon militarily until 2005, which left a political residue that shaped how the refugee influx was received.
This is why Lebanon is different from Turkey or Germany. The relationship was not created by the war, and it will not end with it.
UNHCR recorded 630,697 returns from Lebanon between December 2024 and April 2026, second only to Turkey and from a far smaller starting population. The reasons are not only that Damascus is three hours from Beirut.
Lebanon’s own economic collapse left Syrians there among the poorest people in the country. Renewed hostilities and repeated displacement pushed others. UNHCR has described scaling up its response to returns taking place under force majeure conditions, which is careful language for people leaving because staying became impossible.
For visitors as well as returnees, the Beirut road remains the most used land route into Syria: around three hours to Damascus via the Masnaa crossing. Crossings have been targeted in clashes and can close without notice, so this is a route to take local advice on rather than assume.
Of all the host countries, this is the one where the relationship with Syria is oldest and most complicated.
At its peak, roughly one Syrian refugee for every four Lebanese nationals, in a country of about 5.9 million. No other country absorbed anything comparable per head.
At the Lebanese government's request, UNHCR stopped registering new Syrian arrivals. Every registered figure since has undercounted the people actually present.
Lebanon refused formal refugee camps, so Syrians lived in informal settlements, unfinished buildings and rented rooms spread across the country, which made them harder to count and easier to overlook.
Lebanon's financial crisis left Syrians there among the poorest people in the country, which turned return into a necessity rather than a choice for many.
Syria occupied Lebanon militarily until 2005. That history shaped how the refugee influx was received, and it has not disappeared since the regime fell.
Beirut to Damascus is about three hours, and it remains the most used land route for returnees and visitors alike, when the crossings are open.
