Since the 1950s, the number of forcibly displaced persons recognized by the United Nations has increased drastically; from around 2.1 million international refugees in 1951 to almost 123 million displaced persons in total in 2023. Annual figures are not reflective of the actual number of forcibly displaced people in the world, but rather the number of people identified as such by the UN. Preliminary figures for 2024 show that this figure may now reach the 125 million mark, with major new crises in Sudan and Palestine sending this figure higher, after the Russia-Ukraine War pushed this figure past 100 million people for the first time in 2022. UNHCR The United Nations High Commissioner for Refugees (UNHCR) was founded in 1950 to deal with the large number of displaced persons in Europe in the aftermath of the Second World War. Since then, the scale and geographical scope of its operations has broadened significantly, as it works to provide humanitarian aid, logistical support, and long-term solutions to crises across the globe. The UNHCR played an instrumental role in facilitating or limiting the impact of many decolonization movements across Africa and Asia in the late 20th century, and, in recent decades, it has provided much-needed assistance in conflict areas, such as the Balkans in the 1990s, Afghanistan since the 2000s, and more recently in Syria and Yemen. Alongside the UNHCR, the United Nations Relief and Works Agency (UNRWA) was established in 1949 to provide similar assistance programs for Palestinian refugees and their descendants, and it is currently operational in Jordan, Lebanon, Syria, and the State of Palestine, but its future remains uncertain after the Israeli parliament revoked its license to operate in the country in October 2024. Long-term crises Persistent instability in Sub-Saharan Africa has also been a major area of focus throughout the UNHCR's history, as economic and structural underdevelopment, alongside conflict and political instability, has created several refugee crises that are now in their fourth decade. While countries such as Colombia, Germany, and Turkey have, to varying degrees, successfully managed refugee crises in recent years, the economies of most countries in Sub-Saharan Africa are not equipped to do so. Displacement has placed a great strain on several regions' already-struggling resources, and these are now also being affected by climate change. Countries such as Kenya, Sudan, and Uganda are home to camps or camp networks that house several hundred thousand refugees, with some of the largest in Kenya being established in the early 1990s.

As of mid-2024, Iran was the largest refugee-hosting country in the world. According to data available by the UN Refugee Agency UNHCR, there were nearly 3.8 million refugees in Iran. Turkey was second with more than 3.1 million.

As of mid-2024, Syria had the highest number of refugees who had fled the country. That year, about 6.25 million refugees had left the country, mainly due to the civil war that started in 2011. Second on the list is Ukraine after over six million people left the country since Russia's invasion in February 2022. The third highest number of refugees in the world came from Afghanistan after years of civil wars, instability, and Taliban regaining power in 2021. What are refugees? Refugees are people who have been forced to leave their country because of dangerous circumstances, such as war, violence, famine, or persecution. These circumstances arise from race, religious, ethnic, and/or political persecution, and refugees are unable to return to their home countries due to these conflicts. As of 2022, Turkey hosted the largest number of Syrian refugees. Refugees worldwide The number of refugees, internally displaced people, and asylum seekers worldwide has significantly increased since 2012, much due to the civil wars in Syria and Libya that started in 2011, but also due to increasing instability in the Sahel, the Sudan civil war, the Israel-Hamas war, and the Russia-Ukraine war. An internally displaced person is someone who is forced to leave their home but still stays in their country. They are not legally considered a refugee. Asylum seekers are people who leave their home country and enter another country to apply for asylum, which is internationally recognized protection.

There has never been as many refugees and internally displaced persons (IDPs) in the world as now. The United Nations registered about 32 million refugees and 67 million IDPs in 2024.

The current worldwide refugee crisis is often referred to as the worst humanitarian crisis since World War II. Using Insights for ArcGIS, you'll look at data from 1951 to 2017 and find patterns in the global movement of refugees and asylum seekers.

First, you'll use link analysis to map the movement of refugees from their country of origin to their country of residence. Then, you'll create supplemental charts and tables and dig deeper into the data and the patterns that emerge over time.

In this lesson you will build skills in the these areas:

• Creating a link map
• Filtering data cards, tables, and charts
• Using link analysis to find patterns

Germany had the highest monthly financial allowance for Ukrainians who fled the war compared to other European countries as of June 2022.

People fleeing the war had a right to a residence permit in the EU, enter the labor market, and enroll children in educational institutions. The protection is granted until March 4, 2026, but it can be extended in the future depending on the situation in the country.

In 2023, around 1.93 million people immigrated to Germany. Numbers fluctuated during the time period covered in the graph at hand, peaking in 2015 during the high point of Europe’s refugee crisis. Significantly lower figures in 2020 may be attributed to the first year of the coronavirus (COVID-19) pandemic, and subsequent restrictions implemented by the German government on entering the country, in order to control the spread of the disease. Immigration to Germany “Immigrant” is a term used from the point of view of the receiving country, or the country being migrated to by a person. While reasons for and circumstances leading to an immigrant entering a foreign country may vary, they often include love, include seeking residence, employment, family reunions, or applying for asylum. Various countries are represented among foreigners living in Germany, though currently the leading three by numbers are Turkey, Ukraine, and Syria. Around 5.2 million immigrants living in Germany do not need a residence permit due to having EU citizenship, and therefore being allowed freedom of movement based on EU law. Another 2.64 million immigrants were granted an unlimited permit to stay in Germany. The near future Germany remains a popular choice for immigrants, even in currently challenging economic and political times. Welfare benefits, healthcare, and various support initiatives for those moving to or arriving in the country are on the list of selling points, though in practice, difficulties may be encountered depending on individual situations and laws in different German federal states. While the unemployment rate among foreigners living in Germany had gone up in 2020, it dropped again in the following years, but increased once more in 2023 and 2024 to over 16 percent. The country is Europe’s largest economy, housing many global players in various industries, which continues to attract jobseekers, despite these very industries facing struggles of their own brought on both by the ongoing coronavirus pandemic and geopolitical events in Europe.

Germany was estimated to have the highest total costs from taking in refugees from Ukraine due to the Russian invasion that started in February 2022, at approximately 35.4 billion euros as of December 2024.
