The codebooks, written in English, contain information on SWEOLD’s survey design, sample, response rate and the fieldwork. For every question/variable, there is information on variable construction, frequencies and standard deviations, and a reference to corresponding/comparable variables in previous data waves (including LNU).
The questionnaires are in Swedish and show the exact phrasing and response categories for each question.
