Since the release of the 2018 Canadian Internet Use Survey (CIUS) microdata file, it was noticed that the ‘Valid skip’ (valid skip = 6) and the ‘Not stated’ (not stated = 9) were missing from some of the ‘Universe statements’ in the Codebook (data dictionary).
In general, this issue only impacts questions that rely on a flow from a previous question. Please refer to the questionnaire flow document to ensure that you are using the proper universe when conducting research and creating indicators.
Note, this issue is in the process of being corrected and a new version of the 2018 CIUS codebook will be released when it becomes available.
