Tanzania is among other countries in the world which are affected by the recent global economic slowdown, caused by the COVID-19 pandemic. Therefore, there is an urgent need for timely data to monitor and mitigate the socio-economic impacts of the crisis in the country. Responding to this need, the National Bureau of Statistics (NBS) and the Office of the Chief Government Statistician (OCGS), Zanzibar in collaboration with the World Bank and Research on Poverty Alleviation (REPOA) implemented a rapid household telephone survey called the Tanzania High-Frequency Welfare Monitoring Survey (HFWMS).\n\nThus, the main objective of the survey is to obtain timely data that is critical for evidence-based decision making aimed at mitigating the socio-economic impact of the downturn caused by COVID-19 pandemic by filling critical gaps of information that can be used by the government and stakeholders to help design policies to mitigate the negative impacts on its population.","coll_dates":[{"start":"2021-02-21","end":"2021-03-15","cycle":"Round 1"},{"start":"2021-04-22","end":"2021-05-21","cycle":"Round 2"},{"start":"2021-06-30","end":"2021-07-31","cycle":"Round 3"},{"start":"2021-09-10","end":"2021-10-08","cycle":"Round 4"},{"start":"2021-11-30","end":"2021-12-23","cycle":"Round 5"},{"start":"2022-06-29","end":"2022-07-20","cycle":"Round 6"},{"start":"2023-06-09","end":"2023-07-01","cycle":"Round 7"},{"start":"2023-08-23","end":"2023-09-13","cycle":"Round 8"},{"start":"2023-10-23","end":"2023-11-13","cycle":"Round 9"},{"start":"2024-02-08","end":"2024-02-27","cycle":"Round 10"},{"start":"2024-04-22","end":"2024-05-14","cycle":"Round 11"},{"start":"2024-10-28","end":"2024-11-14","cycle":"Round 12"}],"nation":[{"name":"Tanzania","abbreviation":"TZA"}],"geog_coverage":"National","analysis_unit":"Households\nIndividuals","universe":"The survey covered all de jure households excluding prisons, hospitals, military barracks, and school dormitories.","data_kind":"Sample survey data [ssd]","notes":"These modules were administered in the survey:\n\u2022 Basic Information - Household Roster (Baseline, Round 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12)\n\u2022 Casual Labor (Round 10, 11, 12)\n\u2022 Employment (Baseline, Round 2)\n\u2022 Employment (respondent) (Round 3, 4, 5, 6, 7, 8, 9, 10, 11, 12)\n\u2022 Employment (other household members) (Round 3, 4, 5, 6)\n\u2022 Education (Baseline, Round 2)\n\u2022 Access to Basic Services (Baseline)\n\u2022 Access to Health Services (Round 2)\n\u2022 Access to Essential Goods and Services (Round 10, 11, 12)\n\u2022 Health Access (Round 5)\n\u2022 Mental Health (Baseline)\n\u2022 Food Security (Baseline)\n\u2022 TASAF (Baseline, Round 2, 12)\n\u2022 Non-farm Enterprise (Round 2, 3, 4, 5, 8, 10)\n\u2022 Tourism (Round 2)\n\u2022 Credit (Rounds 3, 4)\n\u2022 Shocks and Coping (Round 3, 4, 11)\n\u2022 Women Savings (Rounds 3, 4)\n\u2022 COVID-19 Vaccine (Round 5)\n\u2022 Youth Contact Details (Round 5)\n\u2022 Economic Sentiments (Round 6, 7, 8, 9, 10, 11, 12)\n\u2022 Food Prices (Round 6, 7, 8, 9, 10, 11, 12)\n\u2022 Fuel Prices (Round 6)\n\u2022 Energy Prices (Round 7, 8, 9, 10, 11, 12)\n\u2022 Transportation Prices (Round 7, 8, 9, 10, 11, 12)\n\u2022 Subjective Welfare (Round 7, 8, 9, 10, 11, 12)\n\u2022 Food Insecurity (Round 7, 8, 9, 10, 11, 12)\n\u2022 Dietary Diversity (Round 7, 8, 9, 10, 11, 12)\n\u2022 Agriculture (Crops and Livestock) (Round 9)\n\u2022 Location Update (Round 11, 12)"},"method":{"data_collection":{"sampling_procedure":"The primary sample for this activity was drawn from the 2014\/15 NPS and 2017\/18 HBS. Target sample completion each month is estimated at 3000 households. The 2014\/15 NPS acted as the primary sample frame, complimented by the 2017\/18 HBS.  \n\nThe sample for the HFWMPS was drawn from the 2014\/15 NPS and 2017\/18 HBS. Both surveys were conducted over a 12-month period and are nationally representative. During the implementation of the surveys, phone numbers are collected from interviewed households and reference persons who are in close contact with the household in order to assist in locating and interviewing households who may have moved in subsequent waves of the survey. This comprehensive set of phone numbers as well as the already well-established relationship between NBS and these households made this an ideal frame from which to conduct the HFWMS in Tanzania.\n\nTo obtain a nationally representative sample for the Tanzania HFWMS, a sample size of approximately 3,000 successfully interviewed households was targeted. However, to reach that target, a larger pool of households needed to be selected from the frame due to non-contact and non-response common for telephone surveys. Thus, about 5,750 households were selected to be contacted. \n\nAll 5,750 households were contacted in the baseline round of the phone survey. [Error!

The variable name is wt_round1.\n\nRound 2 \nHousehold weights\nThe round 1 household weights were adjusted for noncontact and nonresponse as well as calibrated following the same procedures outlined in section 2.2 (steps 4 to 7). The round 2 weights can be found in the household-level data file (r2_sect_a_2_3_4_5_7_8_10). The variable name is wt_round2.\n\nIndividual weights\nGiven the focus on individual education information in round 2 for school-aged members (4-18 years), an additional individual weight was calculated specifically for use with this sample. The round 2 household weight (which includes the household level nonresponse adjustments) served as the base for the individual education weight. Since all members between 4 and 18 years of age were selected, there was no need for a selection adjustment to this weight. Furthermore, there was zero nonresponse among children in the sample (since the information was collected entirely from the main household respondent) so no nonresponse adjustment was likewise needed. However, the weights were recalibrated to reflect current population estimates for five age groups (4-6, 7-9, 10-12, 13-15, and 16-18 years) and by sex. BID Table 7-4 presents the 2021 population estimates used for the calibration. The calibration of the individual weights followed the same approach outlined in step 6 of BID Section 3.0 above for the round 1 household weights. The weights were also trimmed according to step 7 of BID Section 3.0, however the cut offs for the trimming were set at the 2nd and 98th percentiles due to higher volume of outliers in the calibrated individual weights. The variable containing the individual education weight is called educ_wt_r2 and can be found in the individual-level education data file (r2_sect_2_6.dta).\n\nRound 3\nHousehold Weights\nIn Round 3, two different household level weights are provided: cross section and panel weights. The cross-section weights are applicable to the entire round 3 sample while the panel weights are only applicable to round 3 sample households that have been successfully interviewed in all three rounds of the survey so far. For both of these weights, the round 1 household weights were adjusted for noncontact and nonresponse as well as calibrated following the same procedures outlined in section 2.2 (steps 4 to 7). The round 3 weights can be found in the household-level data file (r3_sect_a_2_3_4_5b_7_10). The cross-section weight is contained in wt_round3 while the panel weight can be found in wt_panel_round3.\n\nIndividual weights\nGiven the focus on individual employment information in round 3 for working-age members (15-64 years), an additional individual weight was calculated specifically for use with this sample. The round 3 household weight (which includes the household level nonresponse adjustments) served as the base for the individual employment weight. Since only 4 eligible working-age members between 15 and 64 years were selected, there was the need for a selection adjustment to this weight.
