Refugee crisis

Refugee crisis can refer to movements of large groups of displaced persons, who could be either internally displaced persons, refugees or other migrants. It can also refer to incidents in the country of origin or departure, to large problems whilst on the move or even after arrival in a safe country that involve large groups of displaced persons.At the end of 2020, the UNHCR estimated the number of forcibly displaced people to be about 82.4 million worldwide. Of those, 26.4 million (nearly a third) are refugees while 4.1 million were classified as asylum seekers and 48 million being internally displaced. 68% of refugees originates from just five countries (Syria, Venezuela, Afghanistan and South Sudan and Myanmar). 86% of refugees are hosted in developing countries, with Turkey, hosting 3.7 million refugees, being the top hosting country.

In 2006, there were 8.4 million UNHCR registered refugees worldwide, the lowest number since 1980. At the end of 2015, there were 16.1 million refugees worldwide. When adding the 5.2 million Palestinian refugees who are under UNRWA 's mandate there were 21.3 million refugees worldwide. The overall forced displacement worldwide has reached a total of 65.3 million displaced persons at the end of 2015, while it was 59.5 million 12 months earlier. One in every 113 people globally is an asylum seeker or a refugee. In 2015, the total number of displaced people worldwide, including refugees, asylum seekers and internally displaced persons, was at its highest level on record.

Among them, Syrian refugees were the largest group in 2015 at 4.9 million. In 2014, Syrians had overtaken Afghan refugees (2.7 million), who had been the largest refugee group for three decades. Somalis were the third largest group with one million. The countries hosting the largest number of refugees according to UNHCR were Turkey (2.5 million), Pakistan (1.6 million), Lebanon (1.1 million) and Iran (1 million). the countries that had the largest numbers of internally displaced people were Colombia at 6.9, Syria at 6.6 million and Iraq at 4.4 million.

Children were 51% of refugees in 2015 and most of them were separated from their parents or travelling alone. In 2015, 86% of the refugees under UNHCR 's mandate were in low and middle-income countries that themselves are close to situations of conflict. Refugees have historically tended to flee to nearby countries with ethnic kin populations and a history of accepting other co-ethnic refugees. The religious, sectarian and denominational affiliation has been an important feature of debate in refugee-hosting nations.

An ongoing refugee crisis began in Europe in late February 2022 after Russia's invasion of Ukraine. Over 8.2 million refugees fleeing Ukraine have been recorded across Europe, while an estimated 8 million others had been displaced within the country by late May 2022.
