The codebooks, written in English, contain information on SWEOLD’s survey design, sample, response rate and the fieldwork. For each question/variable, there is information on variable construction, frequencies and standard deviations, as well as a reference to corresponding/comparable variables in previous data waves (including Levnadsnivåundersökningen).

The questionnaires are in Swedish and show the exact phrasing and response categories for each question.
