"With 30.6 million internal displacements in 2017, which is the equivalent of 80,000 people displaced each day, it’s time for an honest conversation, led by affected countries and with support from the international community, on the most effective ways to turn the tide on internal displacement"

Conflict figures

The number of new internal displacements associated with conflict and violence almost doubled, from 6.8 million in 2016 to 11.8 million.

Syria, the Democratic Republic of the Congo (DRC) and Iraq accounted for more than half of the figure.

Disaster figures

There were 18.8 million new internal displacements associated with disasters across 135 countries.

Weather-related hazards triggered the vast majority of the new displacements, with floods accounting for 8.6 million, and storms, mainly tropical cyclones, 7.5 million.

Regional overview

The distribution of internal displacement across the globe in 2017 mirrored the patterns of previous years. Most of that associated with conflict took place in Sub-Saharan Africa and the Middle East, although there was also significant new displacement in South Asia, and East Asia and Pacific. Displacement associated with disasters was most prevalent in East Asia and Pacific, South Asia and the Americas.

Sub-Saharan Africa

5.5M for conflict

2.6M for disasters

Almost half of the new displacements associated with conflict and violence took place in Sub-Saharan Africa. There were 5.5 million in 2017, double the figure for the previous year. Disasters also triggered significant displacement in the region, forcing almost 2.6 million people to flee their homes.

Spotlight - DRC

As many as 2,166,000 new displacements were recorded during the year, second only to Syria, and there were about 4.5 million IDPs in the country as of the end of 2017.

Spotlight - Lake Chad Basin

The heavy security presence in the region and constraints on activities such as fishing, which the militants are said to have infiltrated, have placed an additional burden on returnees, IDPs and their host communities.

Middle East and North Africa

4.5M for conflict

233,000 for disasters

The Middle East and North Africa accounted for 38 per cent of new displacements associated with conflict and violence worldwide, with almost 4.5 million recorded. New displacement was concentrated in Iraq, Syria and Yemen, all of which the UN classified as level-three emergencies. Disasters displaced about 234,000 people across the region.

Spotlight - Syria

An end to the conflict in Syria is still nowhere in sight, but 2017 may have marked the opening of a new chapter.

Spotlight - Yemen

Unrelenting violence and shifting insecurity propelled Yemen to several bleak milestones in 2017: 1,000 days of war, a million suspected cases of cholera, two million people displaced by conflict as of end of year and a humanitarian crisis now widely regarded as the world’s most acute.

East Asia and Pacific

705,000 for conflict

8.6M for disasters

Disasters displaced 8.6 million people in East Asia and Pacific, accounting for 46 per cent of the global total. The region was not immune from displacement associated with conflict, with 705,000 new displacements.

Spotlight - Viet Nam

The combination of hazard intensity, high exposure and vulnerability puts the Vietnamese population as a whole at high risk of disaster displacement. Ten disaster events caused 633,000 new displacements in 2017.

Spotlight - Indonesia and Vanuatu

The responses of the governments of Indonesia and Vanuatu to volcanic activity in 2017 show how effective early warning systems can be in reducing people’s exposure to hazards. They also illustrate the fact that displacement need not always be a negative outcome, in that pre-emptive evacuations save lives and are an effective resilience measure.

South Asia

634,000 for conflict

2.8M for disasters

Disasters triggered most of the displacement in South Asia in 2017, with the exception of Afghanistan where conflict triggered 474,000 new displacements. Many of the 2.8 million new displacements associated with sudden-onset disasters took place in Bangladesh, India, Nepal and Sri Lanka during the monsoon season.

Spotlight - Afghanistan

After almost four decades of conflict and violence, the security situation in Afghanistan deteriorated in 2017 and the country was reclassified from post-conflict to one of active conflict again.


457,000 for conflict

4.5M for disasters

At 4.5 million, the number of people displaced by disasters in the Americas was about ten times higher than the 457,000 who fled conflict and violence in 2017.

Spotlight - the Atlantic Hurricane Season

Ten hurricanes affected around 20 countries and territories, of which six developed into category 3 storms or above. The three major hurricanes, Harvey, Irma and Maria, displaced over 3 million people in the space of a month.

Spotlight - NTCA

There has been a marked upsurge in recent years in the number of people fleeing El Salvador, Guatemala and Honduras – known collectively as the Northern Triangle of Central America (NTCA) – to escape drug related violence, the activities of organised crime gangs, conflicts over land and other generalised violence.

Europe and Central Asia

21,000 for conflict

66,000 for disasters

Three-quarters of the displacement recorded in Europe and Central Asia was associated with disasters. Accurate figures for displacement associated with conflict are difficult to come by. Ceasefire violations along the contact line in Ukraine led to 21,000 new displacements, but a number of issues prevent the accurate profiling of the country’s IDPs. Displacement associated with conflict in Turkey continues to be an extremely sensitive topic. Other governments in the region have stopped reporting on displacement or claim there is none on their territory.

Spotlight - Ukraine

The conflict in Ukraine between the government and pro-Russia separatists in the eastern regions of Luhansk and Donetsk began in 2014 and remains unresolved, despite the Minsk I and II agreements signed in 2014 and 2015.

Total headcount as of end of 2017

A total of 40 million people are estimated to be living in internal displacement as a result of conflict and violence as of the end of 2017. Seventy-six per cent of the world’s conflict IDPs are concentrated in just ten countries, many of which have struggled with high levels of displacement for decades.

An unknown number of people remain displaced as a result of disasters that occur in 2017. The scale of displacement induced by development projects also remains uncertain.

Making progress in reducing internal displacement

Since the publication of the Guiding Principles on Internal Displacement in 1998, programmes and policies to protect and assist IDPs have not been sufficient to cope with, much less reduce, the growing number of new displacements or the cumulative number of IDPs over time. A new approach is essential.

Beyond the need to improve humanitarian responses to these crises, more investments must be made at the national and international levels in sustainable development, peacebuilding, addressing the impacts of climate change and disaster risk reduction.

Authority and accountability should lie with the highest levels of government, combined with the devolution of resources and decision-making power to local authorities. To enable this, national capacity for monitoring, planning and implementation needs to be systematically built and maintained.

Failure to address long-term displacement has the potential to undermine the 2030 Agenda for Sustainable Development and progress on other international agreements.

Inside the GRID

Making the invisible more visible

Accurate measurements of displacement and displacement risk are required to measure progress toward global targets, and an accurate understanding of the dynamics of displacement situations and the needs of IDPs is required for effective action on the ground.

Some of the gaps we encountered were the same as last year, including limited geographic coverage across and within countries, difficulties in distinguishing between new, secondary or tertiary displacements, challenges in obtaining disaggregated and geospatially referenced data on IDPs and their movements, and accounting for all types of displacement.

Part 3 - Inside the GRID


Toward a global framework for national change

Countries facing internal displacement must drive policymaking. Over the coming years, countries will have to better account for IDPs and displacement risk, and make addressing internal displacement an integral part of development planning and governance at both the local and national level.

To make genuine progress at the national, regional and international levels, there needs to be constructive and open dialogue on internal displacement. This must be led by countries impacted by the issue, with the support of international partners, and in line with their national priorities and realities.
