Activity Classification for the Time Use Survey

Glossary

Residual categories

Not elsewhere classified (nec)

A 'not elsewhere classified' (nec) activity category contains activities that are infrequent or unanticipated.

Response unidentifiable

This category is used when there is a response given, but:

1. the response is illegible, or
2. it is unclear what the meaning or intent of the response is – this most commonly occurs when the response being classified contains insufficient detail, is ambiguous or vague, or
3. the response is contradictory for example, both the yes and no tick boxes have been ticked, or
4. the response is clear and seemingly within the scope of the classification but cannot be coded because no suitable option (particularly other residual category options such as 'not elsewhere classified' or 'not further defined') exists in the classification or codefile.

Response outside scope

This category is used for responses that are positively identified (ie the meaning and the intent are clear) but which clearly fall outside the scope of the classification/topic as defined in the standard.

Not stated

This category is only used where a respondent has not given any response to the question asked, ie it is solely for non-response.
