Surveycodings.org is a free service for survey projects, data archives and researchers measuring and coding socio-economic background variables. It provides questionnaires, data collection tools, coding frames and datasets based on standard statistical classifications for a large number of countries and languages for the following variables: industry, occupation, educational attainment, employment status, socio-economic status, and social networks. Provided materials can be used to collect harmonised and cross-nationally comparable data as well as for post-hoc harmonisation of already collected data (e.g. coding of open-ended questions).
Suvreycodings.org is an ongoing project. Therefore, some of the sections of this website are still under development and will be finalised until 2019.
