Executive summary
We analyzed data on the locations of all Digicel mobile phones in Haiti before and after the 12 January 2010 earthquake. This report is an update of earlier reports and covers the period 1 December 2009 to 19 December 2010.
Port-au-Prince area:
The earthquake caused a strong outflow of phones from Port-au-Prince. There was a strong net inflow back to the Port-au-Prince metropolitan area from the beginning of February until early May. From this time onwards, the net inflow decreased and population levels became relatively stable at the end of the analysis period (19 December).
Departments:
A net outflow of phones took place from February in all departments outside Port-au- Prince. The outflow slowed after May. During the rest of the year the net increase of phones in the departments was relatively stable
Return to Port-au-Prince of the people who had left
68% of mobile phones located in Port-au-Prince at the time of the earthquake and that had left Port-au-Prince by 31 January, had returned by 19 December.
