   “An internally displaced person (IDP) is someone who is forced to leave their home but who remains within their country's borders. They are often referred to as refugees, although they do not fall within the legal definitions of a refugee. In 2022, it was estimated there were 70.5 million IDPs worldwide. The first year for which global statistics on IDPs are available was in 1989. As of 3 May 2022, the countries with the largest IDP populations were Ukraine (8 million), Syria (7.6 million), Sudan (7.3 million), Ethiopia (5.5 million), the Democratic Republic of the Congo (5.2 million), Colombia (4.9 million), Yemen (4.3 million), Afghanistan (3.8 million), Iraq (3.6 million), South Sudan (1.9 million), Pakistan (1.4 million), Nigeria (1.2 million) and Somalia (1.1 million). More than 85% of Palestinians in Gaza (1.9 million) were internally displaced as of January 2024. The United Nations and the UNHCR support monitoring and analysis of worldwide IDPs through the Geneva-based Internal Displacement Monitoring Centre.”

   Trends and Patterns of Global Refugee Migration.

   Population and development review (Fransen & de)Published Dec 1, 2021Checked Oct 11, 2026

   “The analysis did not detect a long-term increase in the global intensity of refugee migration. Primarily depending on levels of conflict, refugee numbers have fluctuated at levels of between 0.1 and 0.3 percent of the world population. Apparent increases in numbers of the globally displaced are driven by the inclusion of populations and countries that were previously excluded from the data. While refugee populations continue to be concentrated in countries with low-to-medium income levels, the analysis reveals several geographic shifts in refugee migration. Refugees tend to come from a shrinking number of origin countries and move to an increasing variety of destination countries. This trend seems to reflect a concentration of recurrent conflict cycles in a relatively small number of countries and a parallel increase in the number of safe destinations. Although the vast majority of refugees remain near to origin countries, the average distance between origin and destination countries has increased over time, presumably linked to the greater ease of travel and migration-facilitating networks.”

   Neurologic Care of Forcibly Displaced Persons: Emerging Issues in Neurology.

   Neurology (Mateen et al.)Published Mar 1, 2023Checked Oct 11, 2026

   “We address the terminology of forcible displacement and how terms may differ across a person's migration journey. Common challenges encountered by FDPs with neurologic needs across settings include loss of support systems, loss of personal health information, language barriers and differing expression of symptoms, differing belief systems, epidemiologic patterns of disease unfamiliar to the clinician, and patients' fear and perceived risks of engaging with health systems. Practical approaches are shared for clinicians who encounter an FDP with a neurologic presentation. Finally, the article discusses many unmet neurologic needs of FDPs, which require significant investment. These include addressing lapses in neurologic care during displacement and understanding the effects of forcible displacement on people with chronic neurologic conditions. Future research and educational resources should focus on improving epidemiologic intelligence for neurologic conditions across geographies, developing curricula for optimizing the neurologic care of FDPs, and evaluating the most appropriate and effective uses of health technologies in humanitarian settings.”
