Sometimes people must leave their homes. 

Sometimes people must leave their homes. This is called forced displacement. It is not a choice. People move because they are not safe. 
Many things cause this. Armed conflict is a very common cause. People also move due to natural disasters. For example, a large tsunami in 2004 moved 1.7 million people. 
Climate change can also cause displacement. It can lead to droughts. In 2011, a drought in East Africa made it hard to find food. Some people move because of human-made problems too. This includes violence from criminal groups.
There are different names for these people. If they stay in their own country, they are internally displaced persons. If they cross a border, they may seek asylum. If they are successful, they are called refugees. By the end of 2022, about 100 million people were forced to move. 
Many groups work to help. They try to stop the causes of moving. They also help people in new places.
Forced displacement happens when people must leave their homes. It is not a choice they make. They are forced to move away from their home regions. This can happen because of many different reasons. People might face conflict or violence in their towns. Some move because of human rights violations or persecution. This movement is often called forced migration or relocation. It is a very serious thing that affects many lives. 
There are different ways to describe these people. If someone stays inside their own country, they are an internally displaced person. This is often called an IDP. If a person crosses an international border, they might seek asylum. If they are legally recognized, they are called refugees. A refugee has special legal protections in their new home. Some people move for money, but those are economic migrants. If people move because of big building projects, it is called development-induced displacement.
This topic has a long history. The term "displaced person" became common during World War II. After the war, many people moved from Eastern Europe. Many of these people were from Ukraine, Poland, or the Baltic states. They did not want to return to Soviet-dominated lands. In that time, the term sometimes meant people taken as prisoners. Today, the meaning has grown much larger. It now covers many more types of movement. 
Many things can cause people to leave. Natural disasters like tsunamis or hurricanes are major causes. In 2004, a huge tsunami displaced 1.7 million people. In 2005, Hurricane Katrina moved over one million people in the United States. Climate change also plays a part. It can cause droughts or rising sea levels. Human-made causes are also very common. Armed conflict is a leading reason for people to flee. In Mexico, violence from criminal groups forces families to move. 
By the end of 2022, about 100 million people were forcibly displaced. Most of these people live in the Global South. Many international groups now work to help. They try to prevent these movements from happening. They also work to help people in new regions. Some groups even gather evidence to help people in court. They want to hold those responsible for the displacement accountable. This helps make the world a safer place for everyone. 
Forced displacement is the involuntary movement of people away from their homes. It occurs when individuals or groups are coerced into leaving their home regions. This movement is not a choice made for personal gain. Instead, it is a response to dangerous conditions. The United Nations High Commissioner for Refugees (UNHCR) defines this as movement caused by persecution, conflict, or human rights violations. 
There are specific legal and social terms used to describe these movements. If a person stays within their own country, they are an internally displaced person, or IDP. These people often lack the same international protections as those who cross borders. When a person crosses an international border, they may apply for asylum. If their application is successful, they gain the legal status of a refugee. This status provides them with specific legal protections in their new country. It is important to distinguish refugees from economic migrants, who move primarily for financial reasons. 
Researchers often categorize the causes of displacement into different types. One category is displacement of risk. This includes movements caused by armed conflict, deportations, or sudden disasters. Another category is displacement of adaptation. This involves movement related to development projects or environmental changes. For example, development-induced displacement occurs when people are moved for large projects like the Three Gorges Dam in China. This type of movement is tied to human economic activity rather than immediate physical danger. 
The term "displaced person" (DP) has a significant historical background. It became widely used during World War II. Following the war, many people fled from Eastern Europe. This included many citizens from Ukraine, Poland, and the Baltic states. These individuals often refused to return to Soviet-dominated territories. During this period, the term had a specific meaning. It often referred to people who were removed from their countries as prisoners or slave laborers. Today, the definition has broadened to include many more types of forced migration. 
Natural disasters are a major driver of forced displacement. These can be sudden events or slow-onset changes. A massive tsunami in the Indian Ocean in 2004 displaced over 1.7 million people. In the United States, Hurricane Katrina in 2005 caused more than one million people to become internally displaced. Climate change is also increasing the frequency of these events. Slow changes like sea-level rise or desertification can force people to leave their habitats. These environmental factors can destroy livelihoods and traditional ways of life.
Human-made causes are also extremely common. UNESCO identifies armed conflict as a leading cause of displacement worldwide. In regions like Latin America, Africa, and Asia, political and armed conflicts drive large outflows of people. Criminal activity can also force families to flee. In Mexico, violence from drug cartels and paramilitary groups causes both internal and external displacement. Families move to escape threats like homicide, extortion, or kidnapping. These human-driven actions create urgent needs for safety and relocation. 
The scale of this global issue is immense. By the end of 2022, an estimated 100 million people were forcibly displaced. The majority of these individuals come from the Global South. Because of this, international organizations are working on new approaches. They aim to prevent displacement in home regions and support receiving regions. Some groups even work to gather evidence for legal prosecution. They seek to hold those responsible for causing human-made migration accountable in court.
