DTM recorded 26,259 household displacements (representing 157,554 individuals) who fled, mainly due to conflict (25,258 HHs), across 13 governorates, 94 districts and 948 locations in Yemen during 2021.

This data only represents displacement events in 2021 and does not include people that were displaced in previous years and are still displaced to date. It should also be noted that the total number of identified household displacements (26,259 HHs) in 2021 cannot be added to the total stock of IDPs of 2020 since it contains an unknown number of duplicates (multiple displacements of the same HH) and returns (e.g., HHs recorded as displaced in January 2021 might have returned the following month). 

Similarly, in 2020 DTM identified 28,734 households (172,404 individuals) who were displaced across 13 governorates, 118 districts and 1,249 locations. The slight drop in IDP numbers in 2021 compared to 2020 is most likely due to intensified barriers to movement brought on by the shifting frontlines, worsening security situation and increased access constraints. The nine per cent per cent decrease in observed household displacement instances should not be interpreted as indicative of an improved security situation. On the contrary, in 2021, 91 per cent of IDPs cited conflict as the main reason for displacement, compared to 83 per cent in 2020. Persons displaced during 2020 were also fleeing due to natural disasters, including torrential rains and flooding, which accounted for 12 per cent of displacements.

The first COVID-19 case in Yemen was reported in April 2020, followed by precautionary movement restrictions, which directly limited IDPs’ access to humanitarian assistance. COVID-19 related movement restrictions prevented data collection in some areas and may have contributed to the decreased levels of displacement observed in 2020 and 2021.

Nevertheless, it remains clear that causes unrelated to the pandemic – including conflict, disaster and the challenging socio-economic and political situation – continued to contribute to displacement through 2020 and 2021.

IOM Yemen DTM’s Rapid Displacement Tracking (RDT) tool collects data on estimated numbers of households forced to flee on a daily basis from their locations of origin or displacement, allowing for regular reporting of new displacements in terms of estimated numbers, geography, and needs. It also tracks returnees who returned to their location of origin.

From 1 January 2022 to 9 April 2022, IOM Yemen DTM tracked 5,147 households (HH) (30,882 Individuals) who experienced displacement at least once.

Between 03 and 09 April 2022, IOM Yemen DTM tracked 179 households (1,074 individuals) displaced at least once. The majority of people moved into/within the following governorates and districts:

• Abyan (64 HHs) – Khanfar (37 HHs), Zinjibar (27 HHs) districts. Most displacements in the governorate originated from Al Hodeidah and Taiz.
• Ad Dali (40 HHs) – Ad Dali (20 HHs), Qatabah (20 HHs) districts. Most displacements in the governorate originated from Ad Dali and Ibb.
• Marib (23 HHs) – Marib City (15 HHs), Marib (8 HHs) districts. Most displacements in the governorate originated from Marib and Dhamar.

The majority of people moved from the following governorates and districts   

• Al Hodeidah   (66 HHs) – Hays (28 HHs), Bayt Al Faqih (16 HHs), Zabid (7 HHs) districts.
• Taiz (33 HHs) – Maqbanah (10 HHs), Jabal Habashi (9 HHs), Dimnat Khadir (4 HHs) districts.
• Ad Dali (20 HHs) – Qatabah (16 HHs), Al Husha (3 HHs), Ad Dali (1 HHs) districts.

A total of 9,918 individuals were affected representing 3,672 households. 2,718 individuals from 453 households were internally displaced by disasters. So far in 2022, 14,671 individuals have been affected by disasters, representing 4,800 households. A total of 3,198 individuals representing 533 households have been Internally displaced.

Round 9 of DTM data collection in Nigeria’s north-west and north-central geopolitical zones was conducted between 16
November and 30 December 2021. During the assessments, DTM deployed teams of enumerators to conduct assessments
in 859 wards (down from the 861 wards that were assessed in Round 8 of DTM assessments), located in 177 LGAs (down
from 178 LGAs in Round 8). Eight states were covered, including Benue, Nasarawa and Plateau (north-central) and Kaduna,
Kano, Sokoto, Katsina and Zamfara (north-west).
DTM enumerators conducted assessments in 1,654 locations (a decrease of 10 locations compared to Round 8), including
1,557 (94%) locations where IDPs were residing among host communities and 97 (6%) locations categorized as camps/camplike
settings. In Round 8 of assessments, 1,563 locations where IDPs lived among host communities and 101 camps/camp-like
settings were assessed. During these assessments, data was collected on numbers, living conditions and multisectoral needs
of displaced populations.
DTM activities in Nigeria’s north-central and north-west zones targeted IDPs and aimed to gain a better understanding
of displacement figures and trends, living conditions of the affected populations and the needs and vulnerabilities of these
populations. The population categories are defined in this report as follows:
• An Internally Displaced Person (IDP) is “a person who has been forced or obliged to flee or to leave his or her home or place
of habitual residence, in particular as a result of, or in order to avoid the effects of armed conflict, situations of generalized
violence, violations of human rights or natural or human-made disasters, and who has not crossed an internationally
recognized State border.”
