6.0 STATISTICAL SERVICES 6.1
STATISTICAL BUSINESS REGISTER (SBR)
The Statistical Business Register is a comprehensive list of all formal enterprises and establishments operating in the country at a specified time. It is used as frame for establishment based surveys. At the National Bureau of Statistics, the Register provides an updated list of establishments covering all sectors of the economy as per International Standard Industrial Classifications (ISIC) Revision 4.

The register covers existing formal sectors from administrative sources with fixed premises that fall under the International Standard Industrial Classification of all economic activities revision 4 (ISIC Rev 4), in Tanzania Mainland. Also, includes important information like, name of establishment, telephone number, ownership, number of persons engaged, capital investment and turnover.

6.1.1 Objectives and uses of the SBR (i) SBR is used as sampling frame for different establishments based surveys;

(ii) The register is used to show statistical information on distribution of all economic units, employment by sector and geographical areas. This is very useful to planners and decision makers of the economy;

(iii) It provides a comprehensive list of all enterprises and other units together with their characteristics that are active in a national economy and thus will enhance Government’s policy formulations, forecasting and planning purposes;

(iv) It also used as a guide to investors, other business communities and the general public at large by providing relevant information on name and number of establishments existing to the region and district by Location, industrial activities, ownership and size group;

(v) Used as an input for computing GDP, PPI and other Industrial Indicators; and

Statistical Methods, Standards and Guidelines 118

Outside NBS the following institutions are the major users of the register: Ministry of Labour for factory and industry inspection. Income Tax Department uses for income tax administration and verification. NSSF uses SBR for the administration of worker’s social security.

6.1.2 Methodology of Data Production The main source of the register is through Administrative data sources. Data produced as by- products of Ministries, Departments and Agencies (MDAs) when carrying out their administrative functions.

Another source is through census and surveys carried out by National Bureau of Statistics, such as Industrial Census, Employment and Earnings Survey, Agricultural Census, Hotel Statistics, Education Statistics, Health Statistics, etc.

Since the register is mostly nourished by administrative data and through various census and surveys, NBS conducts Statistical Business Register Survey in order to supplement existing information and update the register, the survey is conducted after every three years.

Survey Designing The survey is designed to gather information from establishments with fixed premises. The SBR survey design addresses the following issues: classification standards, statistical unit and survey coverage.

Statistical Unit This is an entity from which the required data are collected. The basic unit of enquiry for the SBR is an establishment.

Survey Coverage The survey is designed to cover regional and district headquarters, urban wards and urban part of the mixed wards or township areas in Tanzania Mainland. In addition to that, coverage is for those legal establishments with minimum of one employee.

Statistical Methods, Standards and Guidelines 119

Sample Design According to the nature of the survey, all urban wards together with urban part of mixed wards in the district are involved in the survey. The list of establishments from National Bureau of Statistics (NBS), Business Registrations and Licensing Agency - (BRELA), Ministry of Health, Community Development, Gender, Elderly and Children (MoHCDGEC), Ministry of Education and Vocational Training (MoEVT) and Tanzania Revenue Authority (TRA) are used as the sampling frame. The list are used as control sheet during fieldwork.

Survey Instruments The structured questionnaire serves as the main instrument, it is designed to provide the required information. The main variables on which data is collected are: name of the establishment; mailing address e.g. postal box, telephone, fax number and e-mail address; physical location of the establishment; date of its first operation; main activity and auxiliary activities of the establishment; type of ownership; ownership by nationality, volume of sales or value of output (turnover); initial capital investment and sources; registration status; size of the business and number of persons engaged by sex and Education. Other instruments are Instruction Manual and ISIC Rev.4.

Recruitment and Training
Interviewers are recruited by Regional Statistical Managers (RSMs) from their respective region. The number varies for each region depending on the size of the sample for the region. Training is normally conducted in two stages: Training of Trainers (ToT) which involved senior and regional supervisors; followed by training of interviewers and supervisors. The aim of training is to: (i) Pre-test the survey instruments; (ii) Administer questionnaires in the form of a mock interview in order to identify shortfalls in terms of the structure and language of questions used; and (iii) Train supervisors and interviewers on the objectives and instruments of the survey.

Fieldwork
The face-to-face or direct interviewing techniques are deployed as the method of data collection. Interviewers are assigned according to the expected total number of establishments and geographical area of the region.

Statistical Methods, Standards and Guidelines 120

Data Processing
Data processing and analysis is one among the important components of SBR which involved mainly data entry, cleaning, transformation and analysis.

At an earlier stage of the processing, data are keyed in a computer using Census and Survey Processing (CSPro) Software. The final output is produced using Microsoft Excel and Statistical Package for Social Scientists (SPSS) Softwares considering the tabulation plan. The final data set are submitted to the Tanzania National Data Archives (TNADA).

6.1.3 Reference of Applicable Standard Classifications The SBR use the four digit industrial codes to describe the main economic activity of the establishment. The codes are according to the United Nations International Standards of Industrial Classification of activities (ISIC Revision 4) to capture all economic activities in Tanzania Mainland.

6.2
REGIONAL AND DISTRICT SOCIAL ECONOMIC PROFILES Regional and District Authorities are responsible for preparing Social Economic Profiles within their respective areas with technical support from the National Bureau of Statistics. The process of preparing such profiles includes compilation of social economic activities in the Region and Districts.

The profiles cover the region and/or district area and all social economic development activities undertaken in the respective region or district. In social activities the profiles cover sectors like education, health, water and sanitation. In economic activities there are sectors like agriculture, industry, trade, transport and tourism.

6.2.1 Objectives and uses of the Regional/District Profiles The main objective of Regional and District Social Economic Profiles is to provide regions and districts with useful information for planning, policy formulation and appropriate decision making. The information enables regions and districts to identify areas for improvement and also to identify investment opportunities, available in the regions and districts.

Statistical Methods, Standards and Guidelines 121

6.2.2 Methodology of data production Regional and District socio-economic profiles use secondary data from all sectors or departments of the district councils. Templates which cover all these sectors are prepared and distributed to all heads of departments to be filled in. The filled-in templates are then collected for compilation, processing, analysis and production of the report for the respective region or district.
