Executive summary

Heightened gang violence since 12 August 2023 in the neighbourhoods of Carrefour-Feuilles and Savanes Pistache in Port-au-Prince, with a new severe episode on 24 August, triggered significant relocations of the subscriber residents of the participating mobile network operator (MNO) from these zones and neighbouring areas.

Estimates derived from the MNO’s data suggest that at least 1,760 additional MNO subscribers may have left the affected area between 19 and 26 August 2023. Together with the displaced subscribers between 12 and 19 August (see report 1), about 55.3% of the subscribers residing in the affected area have left. Most of the newly displaced subscribers have sought refuge in Tapis Rouge, Avenue Christophe and Pacot. Nine additional neighbourhoods experienced more than 15 newly displaced subscribers. Rankings are detailed in Table 1 on page 2 of the report, showcasing the areas most impacted by this subscriber residents shift. Lastly, as of 26 August, provisional estimates suggest that 5,737 subscribers remained displaced (this figure might include displacements originating from areas other than Carrefour-Feuilles and Savanes Pistache).
