This FAQ provides clear, accessible answers to common questions about using Random Domain Intercept Technology (RDIT) and related approaches to estimate and monitor Internal Displacement (IDP) figures. It is intended for humanitarian actors, researchers, and policy makers working in diverse country contexts.
3iS has supported initiatives in Colombia, Ecuador and Honduras to estimate IDP figures which successfully mobilized donors, informed humanitarian actors, and fostered dialogue with government institutions. In Colombia, displacement estimates closely matched administrative data from the national victims’ registry, particularly after accounting for the proportion of respondents who stated they did not register with the state.
