For many decades, we have provided global healthcare professionals with education and training in humanitarian assistance in sudden onset disasters and conflicts worldwide.
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.
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.
Ongoing population movements out of the Saint-Marc area
- Most of the country has received a small number of travelers from the area during the last week
- A few areas: Gonaive, the areas south of Saint-Marc, Ile de la Gonave and Port-au-Prince, have received the vast majority of travelers from the affected area.
- There is no evidence that more people than usual leave the affected area
We analyzed data from the locations of all Digicel mobile phones in Haiti before and after the earthquake. This report is an update of our report on population movements describing the period up to 11 March. The update extends the analyses in the original report to 18 June.
The new analyzes show that there was a continuous and strong net inflow of mobile phones into the Port-au-Prince metropolitan area from the beginning of February until early May.
We analyzed data from the locations of all Digicel mobile phones in Haiti before and after the earthquake. Our analyses cover the period 1 January to 11 March and include the movements of 2 million mobile phone SIM cards. We matched this data with census data and extrapolated the movement patterns to Haiti's population of 9.9 million persons.
Our results indicate that migration patterns of displaced persons are considerably different from what has previously been assumed, while the overall number of people displaced is similar to previous figures.
A main problem following natural disasters is to estimate the number of affected people. This requires both population data before the event as well as the geographical area affected. For Myanmar it has been impossible to find comprehensive population data below the administrative level of state/division, while the affected geographical area is described per township administrative level.
