GRID 2018 Methodological Annex

The figures included in this report highlight the current state of knowledge of internal displacement on a global scale, and IDMC’s current best estimates for displacement associated with conflict and disasters in 2017. In order to produce figures that are as robust as possible, they go through a rigorous quality assurance process, including comparisons between datasets and source types and multiple partner engagement. Producing comprehensive figures remains a challenge, however, particularly for such a complex, rapidly-evolving global phenomenon. There are data limitations, caveats and definitional questions that need to be considered in order to better understand the data currently available and improve the quality of reporting over time.

To this end, this section highlights some of the main challenges we face and illustrates the most significant caveats to which we call readers’ attention. It describes how we produce our displacement figures by explaining the source data, calculations, definitions and decision rules we use in our analysis. Our aim is to provide maximum transparency so that readers understand the process, can replicate our work independently and make use of our data in innovative ways.
