There is a general consensus that the quality of statistical information covers a number of different dimensions including aspects such as: relevance; accuracy; integrity; methodological soundness; timeliness; accessibility; and serviceability. These dimensions are overlapping and inter-dependent and the relative importance placed on any one of them depends on who is using the statistic and what it is to be used for.
The Data Quality Assessment Framework includes aspects of all the dimensions listed above and is designed to be comprehensive. It allows users of official statistics in Tanzania to understand how any particular statistic has been produced, what processes and mechanisms have been applied to ensure that it is fit for a specific purpose and what controls have been put in place to give the user confidence that it is as objective, accurate and reliable as possible.
The Framework describes different standards and guidelines that have been applied to the organisation and management of the agency that has produced the statistics as well as the measures that have been put in place to ensure the quality of the production process.
