Socio-economic and more general social science variables are widely used in research. However, these variables cannot be measured with scales but require detailed and elaborate categorical classification systems. Some variables also come along with a larger number of answer categories challenging their measurement. The developed tools reduce office coding, less harmonization logistics and save costs by linking survey questionnaires to databases to allow the coding of survey variables during the interview. Database lookups can either replace open questions that need to be post-coded or long-list questions. Tools for several variables are developed and extended within SSHOC and available at surveycodings.org.
