    Series Information

    The Tanzania High Frequency Welfare Monitoring Phone Survey, Round 6 to 12 presents the results of scientific rounds of the Tanzania High Frequency Welfare Monitoring Phone Survey (THFWMPS) which was conducted by the National Bureau of Statistics (NBS) and Office of Chief Government Statistician (OCGS) Zanzibar, in collaboration with World Bank (WB) and the Research on Poverty Alleviation (REPOA).

    Abstract

    This report presents the final results from the last seven scientific rounds of the Tanzania High Frequency Welfare Monitoring Phone Survey (THFWMPS) which was conducted by the National Bureau of Statistics (NBS) and Office of Chief Government Statistician (OCGS) Zanzibar, in collaboration with World Bank (WB) and the Research on Poverty Alleviation (REPOA). The key findings from these high frequency survey rounds are intended to be used to monitor and mitigate the negative impacts of the emerging crisis such as pandemics on the economic and population wellbeing of the country.

    Round 6 to 12 comprises findings from the following key areas; Demographic Characteristics, Employment Status and Reasons for Not Working, Economic Sentiments, Natural Disasters and Climate Events, Access to Essential Goods and Services, Types of Shocks Experienced by Households ( Environmental Shocks and Agricultural Shocks), Transportation Usage for Different Locations in Tanzania (Market Transportation, Workplace and School Transportation and Transport use for health facilities), Household Subjective Welfare Situation , Crop Production and Livestock.

    The objective of Round 12 is divided into two aspects: testing the installed call center gadgets and conducting the Round 12 phone survey. The installed gadgets at the call center were tested to gain insight into how well the center functions and to identify areas for improvement, whether in customer experience, agent performance, or technical infrastructure. The objective of the Round 12 phone survey was to gather timely data to fill information gaps and support evidence-based decision-making for welfare monitoring and understanding the impacts of crises, such as extreme weather events, epidemics, pandemics and any other crises occurred.

    Sampling

    Sampling Procedure

    Phase one of the Tanzania High Frequency Welfare Monitoring Panel Survey (THFWMPS I) draws its sample from various previous face-to-face surveys, including the Mainland Household Budget Survey (HBS) 2017/18, the Zanzibar HBS 2019/20, and the National Panel Survey (NPS) 2014. The inclusion of telephone numbers from most participants of these surveys provides the foundation for the survey sample.

    The target for monthly sample completion is approximately 3,000 households. The NPS serves as the primary sample frame, supplemented by the Mainland and Zanzibar HBS. For THFWMPS Phase II, the sample frame comprises respondents from Phase I who did not explicitly refuse to participate (2,200 households), alongside additional households from the 2021 Booster sample of NPS Wave 5 (NPS 5) households with available phone numbers.

    The Survey Round twelfth conducted from October - November 2024 includes a total of 2,489 households, contributing to the continued monitoring welfare within Tanzanian households
