Q

Quality assurance is a measure to ensure that the Census data is fit for purpose and that the data is not misleading. The ABS has a Data quality framework which ensures that the data is relevant, released in a timely manner, accurate, coherent, accessible, and easy to interpret. The Quality declaration details how the Census addresses each of these elements.
