The 2024 Regional Socio-Economic Insights Survey (SEIS) provides critical data to inform the 2025 Regional Refugee Response Plan (RRP), supporting strategic planning and funding allocation to address regional needs. This consolidated dataset includes comprehensive information from Bulgaria, Czechia, Estonia, Hungary, Latvia, Lithuania, Moldova, Poland, Romania, and Slovakia, covering essential topics such as demographics, protection, education, socio-economic inclusion and livelihoods, health, and accommodation. By synthesizing data from these ten countries, the SEIS offers a detailed view of key areas impacting refugee and host communities, supporting evidence-based decisions for targeted interventions and resource mobilization across the region.
