In this modern age, i.e., the 21 st century, statistical information has become an indispensable input of the development process of a country. Official Statistics produced by the National Statistical Systems, such as the Central Statistical Agency (CSA) are the evidence in which policies are built. They help to identify needs, set goals and monitor progress.

Furthermore, it stands on the role of Official Statistical Systems to build publicly accessible and reliable statistics, which effectively provide a relevant and sound management information system to aid informed decision-making at all levels of government as well as the individual citizen of the country. This in other words means Official Statistics are playing a very important role not only as a basic data input for planning, designing, evaluating and monitoring or reviewing of policies, programs and strategies, but also an information that is indispensable to the public as a whole for making rational decisions. Therefore, it is necessary to steadily develop Official Statistical Systems that are compatible with socio-economic policies and changes, and provide quality data with internationally comparable standards and in an easy to-use form. In-turn, this will contribute to efficient and effective governance through the implementation and follow-up of policies, programs and strategies based on empirical data.
