OUTPUT
STANDARD OUTPUT CATEGORIES
34. For 'Severity of disability' the standard output categories are the same as the standard classification (see the section on 'Standard classification and code structure' above) and may also include the supplementary code 'Not stated' if applicable. The base level categories may be aggregated to the broader categories to which they belong until the desired level of detail is attained. The standard base-level output categories are as follows:
Profound core activity limitation
Severe core activity limitation
Moderate core activity limitation
Mild core activity limitation
Education/employment restriction only
No specific limitation or restriction
No disability or long-term health condition
Not stated
Core core activity limitation
Education/employment restriction only
No specific limitation or restriction
No disability or long-term health condition

35. The hierarchical structure of the 'Severity of disability' classification allows users the flexibility to output statistics at the level of the classification which best suits their requirements. Data can be presented in any of the four standard formats above.
36. Regardless of the level of aggregation envisaged for the dissemination of data, wherever possible, it should be captured, classified and stored at the base level of the classification. This provides the greatest flexibility for the output of data, enables more detailed and complex analysis to be undertaken than if the data is collected and stored at a higher level of aggregation, is more likely to enable comparisons with previous data collected and stored using different classifications to be made, and preserves detailed historical information that may prove useful in the future.
37. However, the constraints affecting each statistical collection, such as problems with confidentiality or standard errors, may not permit the output of data at the more detailed levels of the classification. Nevertheless, the use of a standard classification will enhance data comparability even though it may not always be possible to disseminate the data at the most detailed level.
