Ukraine — Methodological Note — General Population Survey
Starting on 24 February 2022, the Russian Federation (RF) launched a large-scale invasion of Ukraine, triggering an unprecedented humanitarian crisis across Ukraine. Since 9 March 2022, the IOM’s Data and Analytics Unit began systematically conducting a highly representative assessment of the general population in Ukraine to gather information on displacement, mobility flows, intentions, and conditions to inform targeted assistance to the war-affected population. Over the course of March 2022 to January 2023, the IOM’s Data and Analytics successfully carried out 12 rounds of the General Population Survey. Initially conducted bi-monthly and later transitioning to a monthly frequency, the results were extrapolated at both national and macro-regional levels. As of May 2023, the survey methodology underwent adaptation to generate quarterly representative data at the oblast level, thus facilitating localized analysis. This methodological note outlines the comprehensive assessment methodology and sampling design.
