The 10 largest refugee crises to know in 2024

In the past decade, the global refugee crisis has more than doubled in scope. In 2022, the UNHCR announced that we had surpassed the 100 million mark for total displacement, meaning that over 1.2% of the global population have been forced to leave their homes. As of mid-2023, that also includes 30.51 million refugees. Over half of those refugees come from just three countries. These numbers are high — almost beyond comprehension — but each one represents a person who has been forced to leave everything behind due to circumstances beyond their control.

Before we look at the world’s largest refugee crises in 2023, a quick note that we’re focusing specifically on refugees and counting them by country of origin for this listing. For more on that distinction, check out our breakdown of refugees versus IDPs — and all of the other classifications for forced migration.

10. Eritrea

As of mid-2023, over 537,000 Eritreans — nearly 15% of the country’s population — have been displaced abroad due to ongoing violence and political instability. This represents an increase of approximately 36,000 people compared to 2022.

9. Central African Republic

For more than a decade, a humanitarian crisis has raged in Central African Republic. It’s gone largely unnoticed in mainstream western media, however over 750,000 Central Africans were registered as refugees in 2023 — with thousands more displaced internally.

This escalation in violence (which has been ongoing since CAR gained independence from France in 1960) has made it increasingly dangerous for Central Africans to live in the country — and for humanitarian organizations to work there.

8. Somalia

In recent years, the number of Somali refugees around the world had been in decline, registering as less than 800,000 last year. Unfortunately, Somalia’s protracted cycle of crisis has once again lead to an increase in refugees with over 814,000 as of mid-2023.

The situation is dire for many, who are forced to contend with drought, conflict, and hunger. Last year and earlier this year, the country was at the epicenter of the current Horn of Africa crisis and facing famine-like conditions. While rains have broken the drought, the recovery from this crisis will not be swift.

Concern has been in Somalia for over 35 years, as well as neighboring countries that serve as some of the largest host communities to Somali refugees. One key program that we run for both refugees and internally-displaced Somalis is our Cash Consortium, giving people the autonomy and dignity of being able to prioritize their own financial needs with cash transfers. We’ve distributed more than $16 million to over 300,000 people since the launch of the program.

7. Democratic Republic of Congo

The Democratic Republic of Congo remains one of the world’s largest “forgotten” humanitarian crises, with events in a protracted situation rarely making headlines. Combining refugees and IDPs, its displacement numbers are the highest in Africa. This includes over 948,000 refugees — an increase of nearly 100,000 over just two years. In tandem with this, the DRC is also a large host community for refugees from neighboring countries.

Concern has been responding to the DRC crisis for nearly 30 years, with emergency response among our top priorities. We work in partnership with the UNICEF RRMP (Rapid Response to Population Movement), the country’s largest emergency response program.

6. Sudan

Conditions in Sudan have deteriorated throughout 2023 as the country faces some of the worst violence in decades. At the end of 2022, approximately 844,000 refugees around the world were Sudanese. As of mid-2023, that number exceeded 1.02 million, and showed no signs of abating.

Concern has been in Sudan for 35 years and is currently responding to the escalated crisis in both Sudan and neighboring Chad (where many Sudanese have been fleeing).

5. Myanmar

Beginning in August 2017, over 1 million stateless Rohingya fled ongoing violence in Myanmar’s Rakhine State. Many are still living in the world’s largest refugee camp, located in nearby Cox’s Bazar, Bangladesh. The Rohingya represent the majority of the 1.26 million refugees displaced from Myanmar over the last six years.

Together with UN agencies, over 130 local, national, and international nonprofits (including Concern) have supported the Government of Bangladesh to adjust to this increase in capacity. Safety and security remain serious concerns for the Rohingya living in Cox's Bazar, where their informal housing is often destroyed in seasonal floods and fires.

4. South Sudan

The world’s youngest nation is also the site of one of its largest refugee crises, one that entered its tenth year last month. Over 4 million South Sudanese have been forced from their homes, with 2.2 million of those having to leave the country entirely.

Concern has been in South Sudan since it gained independence in 2011 and works to address the ongoing humanitarian needs and the pressure generated by widespread displacement. In addition to working with internally-displaced South Sudanese (many of whom live in Protection of Civilian Sites), we also have a presence in many of the host communities for South Sudanese refugees, including Sudan, Ethiopia, Kenya, and the DRC.

3. Ukraine

In February 2022, escalated conflict in Ukraine led to a full humanitarian crisis, that has displaced over 5.8 million refugees in the last two years. This is more than 13% of the country’s population, and just under 20% of the world’s global refugee population.

Concern began working in Ukraine in 2022, shortly after the beginning of the conflict. After initially working in bordering host communities like Poland and Romania, we switched operations to Ukraine itself, where we determined humanitarian need to be greatest.

2. Afghanistan

The ongoing humanitarian crisis in Afghanistan has made it one of the top countries of origin for refugees. One in every six refugees originated from this country, and over 6.1 million Afghans are internationally displaced — largely in neighboring Pakistan and Iran. (The latest UNHCR data does not yet account for the forced return of thousands of Afghan refugees from Pakistan, which took place in late 2023.)

Concern has been in Afghanistan for over 20 years and recently became the UN’s chosen partner for the emergency response to displacement in the northeastern part of the country.

1. Syria

Syria continues to be the world’s largest refugee crisis as we enter 2024, representing nearly 25% of the total global refugee population. As of mid-2023, 6.49 million Syrians have sought refuge, primarily in Lebanon, Jordan, Iraq, Egypt, and Türkiye . In Lebanon, there are no formal camps, which leaves its population of over 1 million Syrians living across 2,000 communities, often in overcrowded temporary shelters.

Since 2013, Concern has responded to the crisis in Syria, both locally and within refugee communities in Türkiye and Lebanon. In 2019, we also began operating in Iraq.

*All numbers are via the UNHCR’s Refugee Statistics Portal and include refugees under UNHCR mandate. For the purposes of this article, we do not include Venezuelans displaced abroad or Palestinians under UNRWA mandate.

Concern’s work with refugees

Emergency response is part of Concern’s DNA and working with refugee communities in this context has become a core skill for our teams over the last six decades. 

We work with both refugee communities and host countries to ease the pressure that mass displacement can put on a host community. In addition to meeting the frontline needs  — including food, shelter, protection, and other non-food essentials — we also work with refugees on longer-term initiatives, including skill-building and livelihood development and psychosocial support. 

We also put a special focus on the needs of child refugees (who make up 40% of the global refugee population), including education, family support, and providing safe spaces where they can play and enjoy their childhood. 

In 2023, we responded to 66 emergencies in 20 countries, reaching nearly 15.5 million people. This included:

• Playing an essential role in NGO coordination in Chad and collaborating with a consortium of NGOs on the cross-border response to support Sudanese refugees. 
• Rehabilitating temporary shelters in Lebanon, including preparing them for harsh winter conditions, in communities hosting a total of 39,700 Syrian refugees.
• Working with nearly 84,000 Rohingya refugees in Cox’s Bazar, Bangladesh on ways of preventing malnutrition within their families.
