Objectives of the LFS;
The broad objectives of the Labour Force Survey is to obtain comprehensive data on the status of the Labour Market prevailing in Tanzania.
More detailed objectives are:
• To provide measures of both current and usual economic activity,
• To obtain a measure of the size of employment in the informal sector,
• To provide measure of unemployment and underemployment,
• To provide measure of cash income from non-agricultural employment of all types.
Objectives of CLS in Tanzania:
The child labour survey will provide base line on the activities of the child population in Tanzania for planning purposes, policy implementation and monitoring and the evaluation of government programmes aimed at improving the status of children.
The survey will:
• Collect information on the character, nature, size and reasons for child labour in Tanzania, and to determine the conditions of work and their effects on the health, education and normal development of the working child,
• Learn about the characteristics of the sectors where children are working,
• Collect information about the migration status of the children, whether involvement in work has determined the residence for the child/family,
• Create a special data base on activities of children in the country which will be updated as fresh statistical information becomes available through surveys and other administrative records,
• Enhance the capacity of statistical personnel to conduct national surveys on such activities more regularly in the future,
• Produce, present and disseminate to the Government employees and workers organisations, NGOs and the general public, a comprehensive report on child labour in Tanzania giving highlights of the statistical findings and results of the in - depth analysis,
• To intergrate the Tanzania data into ILO's child labour data base so that, Tanzania may be included in a globle trend on child labour.

The 2000/01 Integrated Labour Force Survey was carried out on a sample basis using the National Master Sample (NMS) covering only Mainland Tanzania. The rural component of the sample consists of 100 villages, while for the urban component, 122 EAs (Enumeration Areas) were used. The enumeration areas were selected from those demarcated during the 1988 Population Census.
The objective was to collect data from the usual residents of 3,660 households in urban areas and 8,000 households in rural areas, thus making a total of 11,660 households. The data collected from these households were used to estimate the labour force characteristics for the whole of Mainland Tanzania. In urban areas, 3,660 households or 30 households per enumeration area were selected to represent the urban population. A sample of 80 households in each village was selected to represent the rural population. In order to capture seasonal variations, 20 households out of 80 households were interviewed in each village each quarter.

Type of Research Instrument
The questionnaire design is, of course, a key activity in any survey. The 2000/01 ILFS questionnaire design was relatively simple given that it had all features of the 1990/91 labour force survey questionnaire, except that one copy of the new questionnaire can accommodate up to five members of a household instead of one. Two additional questionnaires CLS1 and CLS2 were included in the 2000/01 survey in order to collect information relating to child labour. Major innovations made to the questionnaire by the technical committee before its final version was printed are as follows:
The statement “list of all members of the household” on LFS1 questionnaire in column 2 was added.
The wording of question no 56 was changed to: “Are the benefits/earnings from this work appropriate in terms of hours under normal circumstances”.
Coding of Question 3.1 in CLS1 under the less than 3 hours was split into two separate codes as follows:- Less than 1 hour each day and 1 - 2 hours, each day. The reason being that the period was too long to capture information of working children.
More questions on informal sector were recommended and it was agreed to include them in the final questionnaire
Pilot test of the Questionnaire
Pilot test of the questionnaire was conducted in Bagamoyo from 15/02/2000 to 25/02/2000. However, preparation for the fieldwork started two weeks before the pilot test. Special permission was obtained from the Pwani Regional Administrative Office. Sensitization in Pilot areas started immediately after District and village officials were consulted.
Training of the LFS/CLS pilot test field personnel took place at the Bagamoyo MANTEP Institute from 15th February 2000 to 24th February 2000. The training included thorough classroom mock interviews and field practice at Kilomo village and Dunda enumeration area. The pilot survey management staff (all from NBS) included five subject matter specialists as trainers and 12 potential supervisors as trainees. Trainees were provided with instruction manuals in Kiswahili and were exposed to interview techniques, consistency checks and adherence to skip patterns.
Printing of Questionnaires
During the first week of April 2000, about 4,500 questionnaires were printed to cover the requirement for training of interviewers and first quarter enumeration exercise. Additional 13,200 questionnaires were printed to cover the requirement of the second, third and fourth quarters of the survey. All printing activities were done at the census printing unit and this helped speed up delivery of the first batch of questionnaires and instruction manuals
