Executive summary
Heightened gang violence since 12 August 2023 in the neighbourhoods of Carrefour-Feuilles and Savanes Pistache in Port-au-Prince continues to trigger significant population movements out of these areas.
Based on anonymous aggregated mobile phone data, we estimate that up to 32,075 subscribers previously residing in the affected areas have since the start of the crisis left the area because of gang violence (most - if not all - are likely to be displaced and in vulnerable situations). Out of these, we can estimate that 9,770 subscribers are currently staying, primarily, in the neighbourhoods of Avenue Christophe (adjacent to Bas Peu de Chose) and Pacot in the Port-au-Prince commune, and Desire - Boutilier in the commune of Petion-Ville - see graph 1 and table 1), in line with IOM-DTM observations from 05 September. For the remaining 22,000 subscribers likely displaced, most are observed to remain within the Port-au-Prince commune, but in neighbourhoods we were unable to precisely determine (whether Avenue Christophe and Pacot and/or other neighbourhoods in the commune).
In the ten-day period from 26 August to 04 September, we estimate that 3,100 subscribers have been newly displaced, notably to Avenue Christophe and Pacot (commune of Port-au-Prince) and Siloe (commune of Delmas) (see table 1). For comparison, they were 2,000 between 19-26 August (8-day study) and 7,500 between 12-26 August (8-day study), showing that the situation is not yet stabilising.

Data considerations
The estimates shown are our best current assessment of movements from non-traditional data: anonymised data from a mobile network operator. However, there are a number of uncertainties. The information should be interpreted together with other available evidence.
