Abstract

The SIGI Tanzania country study aims to provide data that will improve the rights and well-being of women and girls in Tanzania and advance gender equality through the elimination of discrimination in social institutions. The survey focused on the four key dimensions, spanning the primary socio-economic areas that affect the entire lifetime of women and girls: discrimination in the family, restricted physical integrity¸ restricted access to productive and financial resources and restricted civil liberties

The Tanzania SIGI survey was also designed to meet the need for information to report at the national level for assessment of MKUZA, five-year Development Plan III (FYDP III), Sustainable Development Goals (SDGs), especially Goal 5 (Achieve gender equality and empower all women and girls).

It also aimed to provide information on goal 16 which is to “Promote peaceful and inclusive societies for sustainable development, provide access to justice for all and build effective, accountable and inclusive institutions at all levels” specifically for monitoring:
1. Targets 16.1 which is to “Significantly reduce all forms of violence and related death rates everywhere”;
2. Target 16.3 which is to “Promote the rule of law at the national and international levels and ensure equal access to justice for all”;
3. Target 16.6 which aspires to “Develop effective, accountable and transparent institutions at all levels”;
4. Target 16.7 which looks forward to “Ensure responsive, inclusive, participatory and representative decision-making at all levels”;
5. Target 16.10 advocating to “Ensure public access to information and protect fundamental freedoms, in accordance with national legislation and international agreements”;
6. Target 16.b striving to “Promote and enforce non-discriminatory laws and policies for sustainable development”.

The Tanzania SIGI survey has three specific objectives:
• To generate evidence and understand the nature and extent of discriminatory social institutions at both national and sub-national levels across the 31 regions of Tanzania.
• To support the efforts of the Government of Tanzania to address policy challenges related to
gender inequality.
• To share learning on conceptual, methodological and technical issues related to measuring discriminatory social institutions (DSIs) at national level through the production of a background
paper and survey reports, the collaboration of experts, and the organisation of national stakeholder workshops.

Sampling

Sampling Procedure

The sample for the Tanzania SIGI survey was a stratified sample selected in three stages and it utilized some of the enumeration areas of the 2017/18 Household Budget Survey (2017/18 HBS) which used the list of enumeration areas from the 2012 Population and Housing Census (2012 PHC) frame.

In total, 61 sampling strata were formed and stratification was achieved by disaggregating each region into urban and rural areas. The urban and rural areas in each of the regions formed the sampling stratums. The EAs were selected independently in each sampling stratum based on probability proportional to size (PPS). Implicit stratification and proportional allocation was achieved at each of the lower administrative units by sorting the sampling frame within the explicit stratum according to administrative unit in different levels before sampling unit selection.
In the first stage, 217 EAs were selected with probability proportional to the EA size and with independent selection in each sampling stratum with the sample allocation.

Among the selected 217 EAs, (71 EAs were from urban and 146 EAs from rural areas). The selection of EAs was based on the number of EAs in urban and rural areas. With a fixed number of 20 households selected per cluster, the total number of households selected for the quantitative survey of the SIGI Tanzania was 4,340 with 1,420 households in urban and 2,920 households in rural areas)

During the second stage of sampling a fixed number of 20 households (including 12 households which were interviewed in the 2018 HBS and eight (8) new households randomly selected from each selected EA. For selected households, household heads were interviewed. In addition, any household member aged 18 years or above who is most knowledgeable was eligible for the household interviews. Interviews were only conducted with pre-selected households and no replacement was allowed for nonresponding households to prevent bias. Interviewers were asked to make at most three call-backs for nonresponse to reduce nonresponse.

In the third stage, two individuals aged 15 years or above were selected for individual interviews. Selection was done by using a Kish grid. One woman and one man aged 15 years or above who were available on the day of the visit were eligible for the interview

- Design omissions in the sample
- Level of representation
- Strategy for absent respondents/not found/refusals (replacement or not)
- Sample frame used, and listing exercise conducted to update it

Response Rate

The distribution of household interviews and interviewed women and men of age 15 and above; with respect to background characteristics such as for example residence and location. A

In the interviewed households, 4,340 women were selected as eligible for the individual interview and of these, 3,875 were found during the time of the survey. A total of 3,848 eligible women were successfully interviewed, yielding a response rate of 99.3 per cent. In addition, 4,340 eligible men were selected, among whom 3,251 men were found during the time of the survey. A total of 3,220 were successfully interviewed yielding a response rate of 99.0 per cent.

Supervision

The 48 enumerators were involved in the fieldwork - 39 of whom were from Tanzania Mainland and nine from Zanzibar. A total of 16 fieldwork supervisors of which 13 were from Tanzania Mainland and three from Zanzibar were responsible for the day-to-day management of the data collection and quality assurance. There were 16 mobile fieldwork teams that comprised of three enumerators and one supervisor each.

Each team conducted interviews in two regions. Supervisors were responsible to oversee the whole exercise and report to the SIGI coordinator who in turn reported to the project manager. The 31 regions covered by this survey were Arusha, Dodoma, Dar es Salaam, Kilimanjaro, Tanga, Morogoro, Pwani, Lindi, Mtwara, Ruvuma, Iringa, Mbeya, Singida, Tabora, Rukwa, Kigoma, Shinyanga, Kagera, Mwanza, Mara, Manyara, Njombe, Katavi, Simiyu, Geita, and Songwe from Tanzania Mainland; and Kaskazini Unguja, Kusini Unguja, Mjini Magharibi, Kaskazini Pemba and Kusini Pemba from Zanzibar.

Data Collection Notes

Data were collected using Computer Assisted Personal Interview (CAPI) equipped with CSPro software. After completion of the interview, interviewers were able to use internet to upload collected information to the server after being verified by fieldwork supervisors. Before data collection started, supervisors and interviewers were trained from 1st to 6th December 2020
by Trainers from NBS and OCGS to ensure that they are equipped with the necessary knowledge to collect quality data. The training took place in Babati, Manyara Region.

The 48 enumerators were involved in the fieldwork - 39 of whom were from Tanzania Mainland and nine from Zanzibar. A total of 16 fieldwork supervisors of which 13 were from Tanzania Mainland and three from Zanzibar were responsible for the day-to-day management of the data collection and quality assurance.

Data processing

Data Editing

Data for the Tanzania SIGI survey were collected by using Computer Assisted Personal Interview (CAPI) using the CSPro software package. Completed questionnaires were sent via Bluetooth to
supervisors who were responsible for quality assuring and editing the data. The data was then sent to the server before leaving the field.

Data checks were done daily, using STATA. Any errors found were sent back to supervisors to take immediate action to resolve them. To ensure consistency, comparisons were made between data sent by enumerators and supervisors. Data cleaning was completed on 19th July 2021, followed by data processing and analysis from 19th July to 22th July 2021. The analysts used both SPSS and STATA to produce the statistical tables
