USING THE CLASSIFICATION

EDITING SPECIFICATIONS

The full range of valid codes should be used in all specifications, including when validating input codes at editing stage, manipulating data and deriving output items. This is because some responses are given 'not further defined' (nfd) or 'not elsewhere classified' (nec) codes rather than the codes of clearly defined cultural or ethnic groups,

The full range of valid codes includes the classification structure and the supplementary codes and are listed in the ASCCEG data cube.



CODING, STORAGE AND PRESENTATION OF DATA

Regardless of the level of aggregation envisaged for the dissemination of data, wherever possible, data should be captured, classified and stored at the most detailed level (four digit level) of the classification. Collecting and storing data at the four-digit level of the classification allows the greatest flexibility for the output of statistical data, enables more detailed and complex analyses, facilitates comparisons with previous data using related classifications, and preserves information to provide maximum flexibility for future use of the data or that may prove historically useful.

However, because of collection and confidentiality constraints, it may not be possible to collect, store or output data at the lower levels of the classification in all instances. The use of a standard classification framework will nevertheless enhance data comparability even though it may not always be possible to disseminate data at the most detailed level.

The hierarchical structure of ASCCEG allows users the flexibility to output statistics at the level of the classification which best suits their particular purposes. Data can be presented at broad group level, narrow group level, or the base or cultural and ethnic group level. If necessary, significant cultural and ethnic groups within a narrow group can be presented separately while the remaining cultural and ethnic groups within the narrow group are aggregated. The same principle can be adopted to highlight significant narrow groups within a broad group.
