The Question Bank (Qb) website is a resource developed for researchers who wish to view the questionnaires from large scale UK social surveys. Founded in 1995, the Qb is based in the UK but its large body of material can be of use to social researchers anywhere in the world. Most survey questionnaires are held in the form of text searchable PDF files. Many recent surveys are based upon the CAPI program BLAISE, and display the questionnaire in modified coded format. The Qb is intended to help researchers designing questionnaires, secondary analysts in search of surveys covering specific topics, and students of survey methods. It is building up commentary material on the measurement of 22 social and socioeconomic variables. Its longer-term objective is to assist improvements in UK survey measurement practices. The Question Bank is funded by the UK Economic and Social Research Council.
