This paper begins by outlining discussions regarding the“ quality ofstatistics,” noting that the overall framework of the discussion has formedaround 2005 in accordance with the development of discussions and itsimplementation especially in the European Statistical System (ESS).Secondly, it introduces and examines the concepts behind severalcomponents of data quality. The conclusions are as follows: (i) There aresome overlap between the concepts of the different components, bringingobscurity in the meaning of some components. (ii) The component,Relevance has a wide and ambiguous meaning, so we should confine itsmeaning to“ whether or not there is data, and the conceptual validity of thedata.” (iii) Accessibility, Clarity and Interpretability are concerned with thesequence of steps in using statistical data. If we wish to focus on the user’spoint of view, it is desirable to separate two components (Accessibility,which refers to the availability of statistical data, and Interpretability,which mainly means the preparation of metadata and various tools to helpusers understand the data properly). (iv) Comparability can be includedwithin Coherence as a particular case of Coherence. (v) Integrity also hasseveral broad meanings, and is not a property of the data themselves. It is aprerequisite component of statistical services and statistical systems.Thirdly, the paper outlines the relationship between these components asfollows.A. Central components that concern the data themselves:“ Relevance”,“Accuracy”, and“ Coherence”.B. Component that represents the time element of data:“ Timeliness and Punctuality” C. A component that relates to the process of using statistics:“Accessibility and Interpretability”.D. A component that relates to the process of production of statistics“Cost-efficiency (including Respondent Burden).”E. Components that define principles governing statistical activities:“Transparency” and“ Security (including Confidentiality)”. F: Components that refer to the various institutional conditions whichassure the implementation of the abovementioned components. Somemeanings of Integrity relate to them: Professionalism, Legalarrangements, Adequate resources (including securing adequate laborconditions).
