Socio-Economic/Monitoring Survey [hh/sems]
The World Bank is providing support to countries to help mitigate the spread and impact of the new coronavirus disease (COVID-19). One area of support is for data collection to inform evidence-based policies that may help mitigate the effects of this disease. Towards this end, the World Bank is leveraging the Living Standards Measurement Study - Integrated Survey on Agriculture (LSMS-ISA) program to support high-frequency phone surveys on COVID-19 in 5 African countries – Nigeria, Ethiopia, Uganda, Tanzania, and Malawi. This effort is part of a broader first wave of World Bank-supported NLPS that can be used to help assess the economic and social implications of the COVID-19 pandemic on households and individuals.
The recent global economic slowdown, caused by the COVID-19 pandemic, created an urgent need for timely data to monitor the socioeconomic impacts of the pandemic. 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).
Thus, 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.

Sampling
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.
The 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.
To 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.
All 5,750 households were contacted in the baseline round of the phone survey. [Error! Reference source not found. ] presents the interview result for the baseline sample. 49.2 percent of sampled households were successfully contacted. Of those contacted, 96 percent or 2,708 households were fully interviewed. These 2,708 households constitute the final successful sample and will be contacted in subsequent rounds of the survey.
Baseline
An attempt was made to reach all 5,750 households selected from the NPS 2014/15 and HBS 2017/18 sample. However, at the end of the survey 2,829 households were contacted and 2,708 of those were successfully interviewed with complete information. More details on the contact/response rates can be found in Table 7-7 of the BID: Round 1 - Result of Interview.

Baseline
The final household weights for round 1 can be found in the household-level data file (r1_sect_a_3_4_5_6_7_8_10). The variable name is wt_round1.
Round 2
Household 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 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.
Individual weights
Given 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).
Round 3
Household Weights
In 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.
Individual weights
Given 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. For more details, see BID Section 7.3.2 Sample and weights.
