The Tanzania High Frequency Welfare Monitoring Survey was initiated as a response to the need for quality and most frequent statistical data that are needed for planning and making decisions. The data that was needed and collected had relevance in responding to the economic, social, socio-economic shocks that resulted from the outbreak of the Covid-19 pandemic in early 2020. Around 3,000 individuals were contacted through telephone in every round and responded to a questionnaire that was at most 25 minutes long. Most of the modules were revised in each round to capture new emerging issues. The survey was managed by the NBS and OCGS and supported by both the World Bank and REPOA. The report presented covers a number of indicators collected during the five rounds of the survey.
