Labor Force Survey [hh/lfs]
Series Information
The 2020/21 ILFS is the sixth surrvey on labour force to be conducted in Tanzania Mainland. Other surveys of that nature were conducted in 1965, 1991, 2000/21, 2006 and 2014. The integrated labour force surveys are a part of the national programme for production of labour market statistics. This programme requires that, the surveys are conducted after every five yeras. However, there has been delays in conducting ILFS in certain years.This was mainly a result of condictions outside the control of NBS. The next ILFS is expected to be conducted in 2026/27.
Abstract
The main objective of the 2020/21 Integrated Labour Force Survey (ILFS) was to obtain comprehensive data on status of the labour market in Tanzania . Specifically, the survey was meant to obtain estimates on various labour market indicators such as: - Employed Population; Unemployed Population; Economically Inactivate Population; Time Use and Working Children along with their relevant indicators to support analysis.

Sampling

Sampling Procedure
The sampling frame for the 2020/21 ILFS was derived from the inventory of EAs prepared during the 2012 Population and Housing Census (PHC). The sample was designed to provide representative estimates with 95 percent confidence interval in three domains of Rural, Other urban Areas and Dar es Salaam Tanzania Mainland. The sampling design was based on a stratified three-stage design. The first stage involved selection of EAs within each stratum with Probability Proportion to Size (PPS). The second stage involved systematic selection of households within each of the previously selected EAs. The third stage involved selection of respondents for the Time Use Module. A total of 480 EAs were selected at the first stage. At the second stage, a total of 24 households from each of the sampled EAs were selected, equating to 11,520 households.
Response Rate
The overall response rate was 99.97 percent.
Weighting
Principally the basic weight for each sampled household is equal to the inverse of its probability of selection (calculated by multiplying the probabilities at each sampling stage). The sampling probabilities at each stage of selection were maintained in an Excel Spreadsheet with information from the sampling frame for each sampled EA so that the overall probability and corresponding weight was calculated.

Data Collection Notes
Trainings for the 2020/21 ILFS were conducted in two stages, namely:-, the Training of Trainers (TOT); and the Training of Enumerators (TOE). The TOT included all 26 Regional Statistical Mangers (RSMs) from Tanzania Mainland and 5 from Zanzibar. RSMs attended the TOT because they were being prepared for supervision work during data collection. For this reason they were to be adequately knowledgeable on the survey's questionnaires and other survey procedures.
The second level of training was the Training of Enumerators (TOE), which took place from 15th July to 5th August 2020. The TOE was highly intensive and aimed at ensuring knowledge was transferred in a uniform manner to potential field staff. Mode of trainings in the TOE involved classroom lectures, tests, mock interviews and field practice

Questionnaires

Questionnaires
Survey instruments for the 2020/21 ILFS comprised of questionnaires; listing forms; instructions manuals to enumerators and supervisors; and quality assurance guidelines. All the survey instruments were developed by the surveys' Technical Committee in various working sessions prior to the main survey. The questionnaires were developed in English and Kiswahili languages after extensive consultations with stakeholders and data users. The consultations were in form of stakeholders meetings which provided an avenue for discussions between data producers, in this case NBS and OCGS and a wider community of data users. Comments from stakeholders regarding survey instruments were, if needed used to further refine the instruments. The Kiswahili version of the questionnaire was pre-tested in the field to test understanding and applicability of questions. Observations from the pre-test were incorporated in both Kiswahili and English versions of the questionnaires. The instructions manual to enumerators and supervisors were also developed in conjunction with survey questionnaires in both English and Kiswahili languages. The ILFS questionnaires consisted of four modules, namely: - Labour Force (LF); Informal Sector (IS); Working Children (WC); and Time Use (TU).

Data Processing

Data Editing
Data processing involved various activities which included: - receiving data electronically though severs immediately after being edited by the field supervisors; computer editing using logics built in the CAPI; and data analysis and tabulation using Statistical Packages for Social Sciences (SPSS). After editing of each quarters' data, editing reports were generated and sent to regional supervisors to enhance supervision of data collection. After data collection was completed, the four quarterly data files were merged together into a single microdata file. The merging of four quarterly data files was done in such a way that all households in selected EAs maintained a unique identification.
