BRHS postal questionnaires (links below) have been annotated with the BRHS variable names and can be viewed by clicking on the links in the table below (note: some documents are still in preparation).  Questionnaire data notes and coding protocols include 1) information on known data inconsistencies/errors which are important to know about when analysing the data and 2) the coding instructions and category codes used in the coding of open-ended questions.

Data dictionaries contain a list of the questionnaire questions with their BRHS variable names, value range, number of participants who responded to each question and number with a missing response. Category labels corresponding to the numerical data codes in the data can be found directly by viewing the questionnaires. In the case of open-ended questions, the meaning of the data codes can be found in the Questionnaire data notes and coding protocol files.
