Q-Bank is a database consisting of evaluated questions from federal surveys that links each question to the scientific report that evaluated the survey question. Questions are searchable by question topic (e.g. income, demographic, chronic health conditions) and survey title. In addition, users can search for keywords within individual questions. Q-Bank is intended to help users of survey data interpret the survey questions on which the data are based and understand the potential errors that might be associated with these questions.

Q-Bank’s mission is to improve the quality and usefulness of survey data through the sharing of knowledge about survey questions. This allows other agencies, surveys and data users to also benefit from the value gained from our question evaluation projects.

Q-Bank is available to the public at http://www.cdc.gov/qbank
