Between February 5 and April 4, 2025, the International Organization for Migration (IOM) carried out Round 20 of the General Population Survey (GPS), which offers a highly representative assessment of internal displacement in Ukraine. The data in this report, commissioned by IOM, was gathered by 64 enumerators from Multicultural Insights through screener phone-based interviews involving 40,004 randomly selected respondents, alongside follow-up interviews with 1,436 internally displaced persons (IDPs), 1,137 returnees, and 1,804 non-displaced. These interviews were conducted using the computer-assisted telephone interview (CATI) method and a random digit dial (RDD) approach.
This report presents the main findings from Round 20 of the GPS, providing detailed insights into population figures, analysis of displacement flows and mobility intentions, demographic profiles, household composition and vulnerabilities, and the needs of the displaced population. These insights aim to support evidence-based decision-making on strategic, technical, and programmatic aspects of the response and recovery efforts in Ukraine.
