Concept help - Quality Statement
A Data Quality Statement records any known issues that may be related to a data asset. A Data Quality Statement assesses data against seven key factors: Institutional Environment, Relevance, Timeliness, Accuracy, Coherence, Interpretability & Accessibility.
The ABS Data Quality Framework (ABS DQF) provides the standards for assessing and reporting on the quality of statistical information. It can also assist you with the development of statistical collections to produce high quality outputs.
The ABS DQF is based on the Statistics Canada Quality Assurance Framework (PDF, 178.05 KB) and the European Statistics Code of Practice (PDF, 1.09 MB). It consists of seven dimensions of quality: institutional environment, relevance, timeliness, accuracy, coherence, interpretability, and accessibility.

| Interpretability | Is there an abundance of information available about this subject? Is there sufficient metadata to support the data including concepts and classifications? |
| Relevance | An assessment of whether the collection was fit for purpose. What was the target population and whether the collection is representative of that population? Was the response to the collection of the data sufficient to provide reliable information? |
| Accuracy | Whether the data describes what was to be measured correctly. The types and number of errors in the data should be considered when rating this category. If it is known that there were errors in the response or sample or other errors in accuracy of the data, it should be noted. |
| Coherence | Does this collection adhere to known standards about the subject? Is the methodology known and understood widely? |
