6.5 TANZANIA NATIONAL DATA ARCHIVE (TNADA) Tanzania National Data Archive (TNADA) is a web-based cataloging system that serves as a portal for researchers to browse, search, compare, apply for access and download relevant census or survey information.
It provides a powerful instrument that facilitates the process of releasing study metadata and micro data to the user community. It allows for:
Increased quality and diversity of research; Improved reliability and relevance of data; Reduced duplication of data collection activities;
Improved visibility of the institution as their data becomes more frequently used and is more readily accessible;
Increased donor and public confidence in the institution; Improved publishing and dissemination efficiency of the National Statistical Office (NSO); and
Access to survey information such as reports, tables, and micro data.
Twelve Studies have already been uploaded and more are still in the process
6.6 NBS WEBSITE This is the tool developed to assist the National Bureau of Statistics to disseminate its products and services to statistical users and producers in the Government and private sectors.
The presence of NBS website has made it possible for staff and stakeholders to benefit from the shared global information resources and knowledge. The availability of NBS Website (www.nbs.go.tz) has also increased the possibility to collaborate and share information with participating countries and development partners.

Objective
The main objective of the NBS website is to improve access and visibility of the products produced
by the NBS such as survey reports ;which include ; Households Budget Surveys, Economic
Surveys, Population and Housing Census, Agricultural Surveys, and Demographic Surveys.
The focus target groups are;- Government officials including; planners, policy analysts and parliamentarians, researchers, NGOs, media and the public in general.
Methodology The document format used to display and deliver different types of documents on a website is PDF. The end use needs to have Acrobat Reader for PDF to open the document and the internet connection would be necessary for downloading.
6.7 SAMPLING Sampling refers to selecting a subset of elements from a population or a full set of element. The usual goal in sampling is to produce a representative sample. A sample is similar to the population on all characteristics, except that it includes fewer elements bec ause it is a sample rather than the complete population. A perfect representative sample would be a “mirror image “of the population from which it was selected, except it would include fewer elements. The selection of a sample can either be through probability or non – probability mechanism.
Objective To design a representative sample that is cost effective within the agreed timeframe.
Methodology NBS maintains two types of frames, the Population and Housing Census Frame is used to design households based surveys while the CRE is used for designing establishment based surveys. Normally, the households based surveys design use s multistage cluster sampling and elements are selected systematically or a complete coverage is done within the selected cluster. In establishments survey, cut off sampling is common to some threshold establishments revenue while the remaining establishments may be selected using probability proportional to size sampling or systematic sampling.

Reference to applicable standards
All sampling procedures and methods follow international standards using L. Kish (1966) and W.
Cochran.
6.8 ENVIRONMENT STATISTICS
Environment is a cross-cutting issue that involves all sectors of the economy.
Environment Statistics describe the state and trends of the environment in the media of the natural
environment, air, climate, water, land/soil, the biota within the media and human settlements.
Environment Statistics are integrative in nature, measuring human activities and natural events that
affect the environment as well as the impact of these activities and events, also social responses to
environmental impacts and the quality and availability of natural assets.
Main Objective The main objective of producing environment statistics is to enable planners and decision makers to find sustainable solutions to the growing pressure on environment for basic needs. This also helps to increased environment awareness by the general public.
Methodology
Environment Statistics cover all sectors which in one way or another are related to environment.
The information is collected through Routine Data System which comprise s all Ministries,
Departments and Agencies (MDAs ) by sending official letters with required templates . The
collected information is compiled, edited, entered to the computer followed by analysis and
production of report.
The frequency of producing the Environment Statistics Document in Tanzania Mainland is two years,

6.11.1 FINANCIAL RESOURCES
Introduction Financial resources are one of the key elements for successful imp lementation of any institutional goal. In this respect, the NBS strives for availability of adequate financial resources from the government and other sources including commission ed work, loans, and grants from development partners. Government subvention i s mainly for paying staff salaries, production of core statistics and other administrative costs .
Budget process The NBS‟s Budgets are prepared in accordance with Medium Term Expenditure Framework (MTEF) and budget guidelines as issued by the Treasury. The Heads of Department s have overall responsibilities for ensuring that departmental budgets are produced and submitted to the Financial Manager in accordance with agreed timeframe.
The budget committee is formed to facilitate and consolidate budget input s from all departments and submit to NBS management and later on scrutinized by the Directorate of Finance.

Commissioned Work Apart from Government subvention, the NBS generates its own revenue from commissioned work which forms an important source of internal revenue for NBS.
6.12 GEOGRAPHICAL INFORMATION SYSTEM- (GIS)
Introduction A Geographical Information System (GIS) is a computer based system which is used to digitally produce and/or reproduce and analyze the features present on earth surface and the events that take place on it. A GIS is an information system designed to work with data referenced by spatial /geographical coordinates. In other words, GIS is both a database system with specific capabilities
Statistical Methods, Standards and Guidelines
105 for spatially referenced data as well as a set of operations for working with the data. It may also be considered as a higher order map.
Components of GIS
GIS constitutes of five key components:
Hardware - Consists of the computer system on which the GIS software will run
Software - GIS software provides the functions and tools needed to store, analyze, and display geographic information
Data - Geographic data and related tabular data can be collected in-house or purchased from a commercial data provider. The digital map forms the basic data input for GIS
People - GIS users range from technical specialists who design and maintain the system to those who use it to help them perform their everyday work
Method - The models and operating practices unique to each organization
1.0 Mapping Concepts, Features and Properties
A map represents geographic features or other spatial phenomena by graphically conveying
information about locations and attributes. Location information describes the position of particular
geographic features.
The basic objective of mapping is to provide: Descriptions of geographic phenomenon Spatial and non-spatial information Map features like Point, Line, and Polygon.
1.1 Map Features
Location information is usually represented by points for features such as wells and telephone pole
locations, lines for features such as streams, pipelines and contour lines and areas for features such
as lakes, counties and census tracts.
