Executive summary
Key observations for the period 01 November 2025 - 31 August 2026
- NOTE: In the Southern Region, service availability remained reduced in early August 2026 after fiber optic damage, with service recovering mid-month; estimates for Grande'Anse, Nippes, South and South-East are based on a smaller sample during this period.
- NOTE:Due to partial and low population coverage of the data used, the estimates shown in this report may contain biases. Particularly for the departments Artibonite, Centre and North-East and North-West, data is available only for a small number of sections.
- In the Port-au-Prince Metropolitan Area (ZMPAP), 2e Section Morne l'Hôpital remains the largest increase nationally (+11,210) but levelled off since July, while 1re Section St Martin (Delmas) rose to +3,610. 1re Section Turgeau remains the largest decrease (-9,640), stable since June.
- In contrast, 5e Section Bellevue Chardonniere (Pétion-Ville) is now +1,440, down from +2,440 in the July report, reversing several months of increase, while 10e Section Thor (Carrefour) declined further (-2,590).
- Outside ZMPAP in West, 3e Section Sourcailles (Kenscoff) remains the largest decrease (-2,200), the monthly estimates having fallen between June and July, coinciding with armed attacks in Kenscoff on 4-8 July that displaced 5,840 people, 36% of them to Pétion-Ville (ETT100.1).
- In Artibonite, 2e Section Bois Neuf (Saint-Marc) declined further to -4,110, the third largest decrease nationally; IOM DTM recorded around 11,000 people displaced in the department between 6 and 28 July (ETT101.2, ETT102, ETT103), largely from sections with little or no data coverage.
How to use this report
We provide population estimates that take into account population movements within Haiti, per month and per communal section. The current crisis has led to large population movements, particularly of internally displaced people (e.g. IOM round 9), which can result in population statistics becoming outdated over a few months, and therefore impairing preparedness efforts (e.g. hazard population exposure estimation, needs assessment, service and contingency planning).
Indicators presented
Estimated change: the difference in the estimated population between the first and last months of the 12 month reporting period, which does not reflect any monthly variation within.
For communal sections with fewer than 10 months of resident estimates during the reporting period, we do not make a trend classification (insufficient data). For monthly population estimates at the department level, we carry forward the latest estimate to fill missing months in a communal section so that the aggregated changes at the department level are only based on observed CDR-derived mobility.
For communal sections with fast changing populations, we categorised them as ‘increasing’, ‘decreasing’; ‘stable’, when there is little to no change; or as ‘fluctuating’ when large month-to-month changes prevented us from detecting a trend.
Data used
- This report uses our v4.0 dataset (documentation, release notes), available at https://haiti.mobility-dashboard.org.
- Monthly estimates of population per communal section (the “de facto” population) - derived from anonymous mobile phone data, weighted using survey data but unadjusted for population change due to births, deaths, immigration and emigration - only considering internal mobility in Haiti.

Data privacy & governance
No personal data, such as an individual’s identity, demographics, location, contacts or movements, is made available to the government or any other third party at any time. All results produced by Flowminder are aggregated results (for example, subscriber density in a given municipality), which means that they do not contain any information about individual subscribers.
This data is fully anonymised. This approach complies with the European Union’s General Data Protection Regulation (EU GDPR2016/679). Data is processed on a server installed behind the mobile network operator’s firewall in Haiti, and no personal data eaves the operator’s premises.
Data considerations
The estimates shown are our best current assessment of movements. However, there are a number of uncertainties. The information should be interpreted together with other available evidence.
