Chapter 3 violence was particularly acute in Port-au-Prince, forcing many to flee within Port-au-Prince and to other provinces, where they were predominantly hosted by local families. By the end of 2024, most IDPs were hosted in the West and Great South regions (39 per cent in each), rather than in Port-au-Prince as in previous years.157 In Myanmar, 1.4 million people were newly displaced during the year with the number remaining displaced reaching 3.5 million at endyear. See the Spotlight on the Myanmar Situation section above for more details. Now in its fourth year, the international armed conflict in Ukraine continued to drive displacement. During 2024, nearly three-quarters of a million (740,000) Ukrainians were newly displaced within the country. A similar number of IDPs were estimated to have returned during the year (782,000), with 3.7 million IDPs remaining displaced at end-2024, a figure unchanged from end-2023. In 2024, the intensity of the fighting increased in the eastern and southern parts of Ukraine. In Yemen, nearly 367,300 people were forced to flee sporadic clashes in several regions,158 causing an increase of 6 per cent in the overall number of IDPs within the country, which at the end of 2024 stood at 4.8 million. Demographics of IDPs Reliable demographic and sub-national estimates of IDPs are vital for guiding UNHCR and its partners in their efforts to protect and assist displaced populations. In 2024, sub-national data on IDPs was reported for 31 countries and covered almost all (98 per cent) of the total IDP population protected/ assisted by UNHCR. Based on the available data, at least 42 per cent of IDPs reside in urban areas,159 and approximately one-quarter live in settlements, including camps,160 both in urban and rural settings. Age- and sex-disaggregated data for IDPs was available for 16 countries, 2 fewer than the previous year. This represents 58 per cent of the IDP population reported by UNHCR, while sex disaggregation was available for 60 per cent of the IDP population. Women and girls made up 53 per cent of all IDPs, while children accounted for 46 per cent of IDPs worldwide. Countries with the highest proportion of internally displaced children included Somalia (66 per cent) and Burkina Faso (56 per cent), while the lowest proportion of children were reported in countries such as Mexico (19 per cent) and Ukraine (24 per cent).161 Displacement in the context of disasters In addition to conflict and violence, people were displaced within their countries due to disasters, with record levels reported in 2024. Disasters include people displaced due to extreme weather events, such as floods and storms, and those displaced due to geophysical events, such as earthquakes. The global forced displacement does not include people displaced due to disasters. During the year, 45.8 million internal displacements due to disasters were reported, with 9.8 million people remaining displaced within their own country at the end of 2024, according to the Internal Displacement Monitoring Centre.162 Disaster-related internal displacement accounted for 70 per cent of all new displacements in 2024. Slightly more than half of all disaster-related displacements (54 per cent) were triggered by cyclones. 157 See Report on the displacement situation in Haiti — Round 9 (December 2024), IOM. 158 See UN warns of escalating conflict in Yemen amid humanitarian crisis, regional tensions, UN news. 159 In the reported data, 61 per cent of locations are classified as “various”, i.e. they include both urban and rural locations. Based on the countries in which these are reported, it is likely that the actual proportion of IDPs in urban areas is higher than the reported 42 per cent. See the summary by urban and rural location in annex 14. 160 See Settlement Typologies in Emergencies and the definitions of settlement types and the summary by accommodation type in annex 14. The proportion in camps or settlements includes formal settlements, informal settlements, collective centres and transit centres. The type of accommodation is reported as unknown for approximately 35 per cent of the global IDP population. UNHCR estimates that where the accommodation type is unknown, it is much less likely that the IDPs are in settlements, which typically have centralised, managed services. 161 The proportion of children among people displaced internally in Ukraine (24 per cent) is significantly higher than the proportion among the Ukrainian population as a whole (18 per cent). 162 See footnote 15. 44 UNHCR > GLOBAL TRENDS 2024
