Executive summary

According to IOM DTM (Emergency tracking #28), armed attacks in Cité Soleil have led to the displacements of over 1,000 people over 13 - 16 November. Our estimates based on anonymous aggregated mobile phone data up to 25 November shows that at least 1,070 subscribers residing in neighbourhoods located to the North of Cité Soleil (Sarthe, Terre-Noire-Blanchard, Bas Fontaine, Duviviers, Village des Rapatriés, Menetas) have been displaced while an additional 730 subscribers are likely displaced. Out of this grand total of 1,800 displaced subscribers, 650 have stayed within Sarthre and Terre-Noire-Blanchard, 420 have been displaced to the communes of Croix-des-Bouquets, Delmas, Petion-Ville and Tabarre (as per DTM observations) and the 730 remaining cannot be located because of method limitations. Few displacements are observed outside of the ZMPP: toward the west of Carrefour (communal section Morne a Bateau ) and the south of Petion-Ville (communal section Montagne Noire), these are not shown on the maps. Longer displacements may have occurred,e.g. to Les Cayes, as in DTM’s report, but were not observed. A few displacements have also been observed in the South of Cité Soleil (Boston, Brouklin and Bélécou neighbourhoods) in line with DTM estimates (not reported here because of their too low numbers). Resident numbers in North Cité Soleil appear to sharply drop, then quickly recover from 22 November onward; however, further monitoring is needed to understand whether this indicates that displaced subscribers are returning to the affected area or whether this may be due to an artefact of the data.

About this report

Authors & contributors

This report was authored by the Flowminder Foundation, by Galina Veres and Veronique Lefebvre, with the contribution of Robert Eyre, James Harrison, Sophie Delaporte, and Xavier Vollenweider.

Galina Veres analysed, interpreted and wrote the report; Veronique Lefebvre directed the analysis; Robert Eyre supported the analysis, James Harrison produced the aggregates derived from CDR data; Sophie Delaporte supported with information product design, report review, translation and data visualisation; and Xavier Vollenweider supported with report writing.

This study was made possible thanks to the anonymised (aggregated) Call Detail Records provided by a mobile network operator 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.
