Information about household members is usually sought of one adult only responding on behalf of others in the household – a method that precludes asking subjective questions, and raises concerns about the accuracy of some of the data collected. For example, while it can be expected that one household member will know the employment status of all other household members, is it reasonable to expect them to know more specific details of their employment arrangements (such as hours of work)?
