Executive summary
Key observations for the period 01 November 2025 - 30 September 2026
- NOTE: Estimates (v5.0) now use voice call, SMS and mobile data session records, and are not comparable with previous reports, which used voice call records only. There is currently a gap in mobile data session records up to May 2026. We are working with Digicel to fill it, and future releases may revise some estimates.
- NOTE: Partial and low population coverage may bias the estimates, particularly in Artibonite, Centre, North-East and North-West, where full data for the period are available for only a few sections.
- In the Port-au-Prince Metropolitan Area (ZMPAP), 2e Section Morne l’Hôpital (Port-au-Prince) recorded the largest estimated population increase nationally (+12,100). The largest decreases were in 1re Section Turgeau (Port-au-Prince) (-11,300; stable between June and September 2026), 10e Section Thor (Carrefour) (-6,390; declining since May) and 3e Section Bellevue (Tabarre) (-4,900).
- In West outside ZMPAP, the largest estimated decrease was in 3e Section Sourcailles (Kenscoff) (-3,370).
- In Artibonite, the estimated population of 2e Section Bois Neuf (Saint-Marc) declined overall ( -2,620) with partial recovery May-July, renewed decline August - September 2026 .
- In Nippes, 2e Section Anse aux Pins (Plaisance du Sud) recorded the largest increase outside West (+1,470).
- In South-East, the estimated population has declined by 1,700 since November 2025, with the largest decreases in 5e Section Bas de Grandou (Bainet) (-1,230) and 4e Section Fond Jean Noël (Marigot) (-1,140).
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particularly of internally displaced people (e.g. IOM round 9), which can result in population statistics becoming outdated over a few months, and therefore impairing preparedness efforts (e.g. hazard population exposure estimation, needs assessment, service and contingency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 v5.0 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.
