What is 4Mi?
4Mi offers a regular, standardized, quantitative and globalized system of collecting primary data on mixed migration flows. It is managed by the Mixed Migration Centre under the overall auspices of the Danish Refugee Council.
Since 2014, 4Mi has been developing a unique network of field monitors situated along frequently used routes and in major migratory hubs. These monitors conduct in-depth interviews with adult migrants and refugees on a continuous basis. In some locations, they also interview smugglers and others involved in the facilitation of mixed migration. Monitors are trained and closely supervised and use a smart phone-based survey application to record and transmit completed interviews to regional 4Mi hubs for validation and analysis. On average, 4Mi collects more than 1,000 interviews per month.
4Mi uses a closed-question survey to invite respondents to anonymously self-report on a wide range of issues that results in extensive data relating to individual profiles, migratory drivers, means of movement, conditions of movement, the smuggler economy, aspirations and destination choices. For particular projects, ad hoc surveys and additional survey modules are also used.
