Executive summary
Key observations for the period 01 November 2025 - 31 May 2026
- Overall, most communal sections show stable population estimates or minor changes (±500 people) between November 2025 and May 2026, and/or between April and May.
- In the Port-au-Prince Metropolitan Area (ZMPAP), the population continued to increase in 2e Section Morne l'Hôpital (Port-au-Prince) (+11,720), 1re Section St Martin (Delmas) (+3,350), and 5e Section Bellevue Chardonniere (Pétion-Ville) (+2,730) between November 2025 and May 2026. From April to May 2026 the population increased in 3e Section Bellevue (Tabarre ) by +2,280 people. Increase in the population in Delmas and Tabarre is potentially due to refugee arrivals following clashes (ETT93.2). In contrast, the population of 3e Section Etang du Jonc (Petion-Ville) continues to decrease (-2,630), while the population in 1re Section Turgeau (Port-au-Prince) remains stable after a sharp drop in January 2026.
- In West outside ZMPAP, the largest population increase was recorded in 3e Section Petit Boucan (Gressier) (+1,540), while the largest population decrease was in 9e Section Bizoton (Carrefour ) (-1,590).
- In South, the estimated population of 1re Section Bourdet (Les Cayes) increased sharply from April to May by +1,680, while 2e Section Fonfrede (Les Cayes ) decreased from April to May (-1,190).
- In South East, the estimated population declined by 2,500 since November 2025, with the largest continuing decreases in 6e Section Montagne La Voûte (Jacmel) (-1,540), 5e Section Bas de Grandou (Bainet) (-1,050) and in 3e Section Macary (Marigot) (-1,050). The population continued increasing in 10e Section La Vanneau (Jacmel) (+2,470) and 1re Section Bas Cap Rouge (Jacmel) (+1,330). The population decrease in Marigot and increase in Jacmel is potentially due to armed attacks (ETT89.1).
- NOTE: The Flowminder-Digicel pipeline was interrupted from June to October 2025, with no data currently available for that period.
- NOTE: Due to partial and low population coverage of the data used by Flowminder, 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.
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.
