Labor Force Survey [hh/lfs]
Abstract
The 2006 Integrated Labour Force Survey (ILFS) was the fourth such survey to be conducted by the Tanzanian government in collaboration with development partners and other stakeholders. This survey was similar in many respects to the 2000/01 ILFS. However, in addition to topics covered in that survey, the 2006 ILFS for the first time included time use module. The 2006 ILFS was, among others, intended to meet the data needs for monitoring of the National Strategy for Growth and Reduction of Poverty (NSGRP) or MKUKUTA in respect of economic growth and reduction of income poverty.
The ILFS was implemented on behalf of the government by the National Bureau of Statistics (NBS) in collaboration with the Ministry of Labour, Employment and Youth Development. The survey was funded by the government of Tanzania through the Vice Presidents Office, Poverty Eradication Division in collaboration with development partners. This report was written by a team of Tanzanians which included staff from the NBS, Ministry of Planning, Economy and Empowerment, Ministry of Labour, Employment and Youth Development, Research on Poverty Alleviation, and Tanzania Gender Networking Programme.
Objectives
The main objective of the survey was to provide up-to-date data needed by the government and other stakeholders on human economic activities, and particularly those related to the informal sector and its magnitude, unemployment, underemployment, child labour and time use.
Lack of such data hinders government and other stakeholders in their endeavours to plan and implement strategies aimed at proper use of the available resources so as to improve the quality of life and social well-being of the people of the country as documented in cluster two of the NSGRP.
An additional specific objective was to fill the gap caused by lack of data on time use due to the absence of an established system of conducting research on this topic.
The National Employment Policy of 1997 attaches great importance to the contributions made by the private sector and the informal sector to national economic growth. The government’s commitment to creating employment opportunities for the people of the country was reinforced by enactment of the National Employment Act of 1998. These developments increased the need to conduct the survey in order to determine the magnitude of the labour force in the country. The survey was also intended to collect information on employment status so as to introduce necessary changes in the country’s employment policies where needed.
The inclusion of modules alongside the standard labour force questions was aimed at meeting specific demands of the main data users. The government as the main data user was interested in labour force data in general. The ILO was especially interested in the child labour module as a means of determining the extent to which children are denied their basic rights such as schooling due to being involved in economic activities. TGNP was interested in the time use module in order to observe gender disparities resulting from performance of various economic activities at the family, community and national levels. The time use component was implemented with the technical support of an expert from the Republic of South Africa.

Sampling
Sampling Procedure
A three-stage sampling technique was agreed upon during the planning stage, which started in November 2005 and ended in December 2005 before the execution of the fieldwork for the ILFS.
The sampling was based on the National Master Sample (NMS) that covers Tanzania Mainland and Zanzibar. A similar approach was adopted at the planning stage of the 2000/01 ILFS. Sampling was done by the NBS in collaboration with an expert from the University of Dar es Salaam. This report analyses the data collected in Tanzania Mainland.
A simple random sampling technique was adopted at the first stage of sample design to determine representative samples of villages (140) and EAs (244) in rural and urban areas respectively. The villages, and enumeration areas (EAs) were demarcated during the 2002 Population and Housing Census.
The second stage involved random selection of 80 households in each selected village and 30 households in each selected urban EA. This was then followed by the third stage of sampling which involved random selection of households to form representative samples of 20 and 30 households in each selected village and urban EA respectively that have to be interviewed in each quarter of the year. Five questionnaires focusing on different aspects were then administered in each of those households. The time use questionnaire was, however, administered only in every fifth household in the sample

Response Rate
The realised response for the standard labour force questions was 16,445 households giving a response rate of 88.8 percent and covering 72,442 individuals
Weighting
Weighting calculations were done by the data processing personnel under the guidance of the sampling expert from the University of Dar es Salaam. Criteria and assumptions applied in the calculations were similar to those developed during the 2000/01 ILFS. Calculations were done separately for rural and urban clusters. The correction factors for rural and urban clusters were 1.2054 and 1.2869, respectively. The attached table in the Appendix summarizes the results of the adjusted weights and population for all clusters.

Data Collection Notes
Execution
Fieldwork took place in 2006, and was organised in four quarters so as to capture seasonal variations. The target sample size was 18,520 households, with 7,320 and 11,200 households from urban and rural areas respectively. The realised response for the standard labour force questions was 16,445 households giving a response rate of 88.8 percent and covering 72,442 individuals. The target sample size for the time use component was 3,704 households with 1,464 and 2,240 households from urban and rural areas respectively. The realised response for the time use component was 3,193 households giving a response rate of 86.2 percent and covering 10,553 individuals.
Recruitment
Administrative care was taken to recruit qualified persons to perform the necessary tasks at all stages of the survey. Staff recruited included field workers, Regional Statistical Managers and national supervisors. A total of 186 fieldworkers were recruited, of whom 39 were females. Most of them had attained ordinary secondary level education while a few had attained advanced secondary level education.
Training
Training of master trainers was done at national level in Morogoro in 2005. This was followed by training of field staff in six zones covering all 21 regions of Tanzania Mainland. The training was intensive and aimed at ensuring that the knowledge was transferred in a uniform manner to potential field staff.. Class tests were administered in some zonal training centres to assess understanding. Both the national and zonal stages of training included class lectures, exercises and field work practice in selected rural and urban areas.
Fieldwork
Regular field visits for ensuring close supervision were made by national and regional supervisors. This was intended to minimise possible errors made by field staff who were instructed to make field edits at the household as soon as they finished the interview. This practice was intended to ensure that the quality of work was maintained at all stages of data production.

Questionnaires
Questionnaires
Questionnaire design was done after extensive consultations with data users and other stakeholders in order to satisfy their respective demands for data. Questionnaire review was done in May 2005, and the questionnaire pre-tested in July 2005 in both rural and urban areas. The ILFS consisted of five questionnaires for taking care of the modules as needed by data users. The first questionnaire (LFS1) was administered to the head of the household or his/her representative. It was intended to collect household particulars. The second questionnaire (LFS2) collected labour force details for individuals. The third questionnaire (CLS1) was administered to parents or guardians of all child aged 5 to 17 years. The fourth questionnaire (CLS2) was administered to children aged 5 to 17 years. The fifth questionnaire, on time use (TUS), aimed to collect information on the routine activities of respondents. The TUS questionnaire was administered on seven consecutive days to each member aged 5 years and above of selected households.
Data Processing
Data Editing
Data processing was carried out as soon as questionnaires were received from the field. The first stage included questionnaire reception and manual checking of the number of clusters (EAs) in a region and the number of households in each cluster. This was followed by manual editing and coding of questionnaires before data entry. A special data entry program in CSPro was developed by programmers to capture the data. Data cleaning and validation were done by experienced data processing personnel. Once the process of data cleaning for both the ILFS and TUS data was completed successfully, the ILFS National Technical Committee met and reviewed the preliminary results. The committee found that the overall quality of data was good. The data processing personnel was informed about any identified errors and inconsistencies that needed correction. The South African time use consultant assisted in capacity building of ILFS staff, and particularly of the data processing team.
Other Processing
A special data entry program in CSPro was developed by programmers to capture the data. Data cleaning and validation were done by experienced data processing personnel.
