The World Bank team collaborated with UNICEF Armenia and jointly implemented four rounds of HFPS to assess household vulnerabilities and children welfare after the outbreak of the COVID-19 pandemic. The first wave (comprising surveys I & II) was conducted in July - December 2020, and the second wave in May - June 2021 (comprising surveys III & IV). These data will improve understating of the socio-economic consequences of the pandemic and restrictive measures on households and children and support the development of better response and recovery strategies for addressing COVID-19. The surveys included a sample of 4,556 households for Survey I, and 1,642 households with children for Survey II. The sample size is 2,026 for Survey III which includes modules on households with migrants, and it is 2,007 for Survey IV which contains modules focusing on households with children.
