These data files and associated web-based summary programs are designed to provide public access to analysis results from BBS data. Primary results are provided in spreadsheet form, and are described in this metadata, and website elements present the results in alternative summary formats. A statement regarding the elements of the website, and a general discussion of the methods, is available at ( Analysis of survey data can be controversial, and any user of the information should recognize that alternative approaches exist. These results are based on methods that have been accepted in the published literature. Users also have access to all data collected by the survey, at ( Standard disclaimers for use of information are also provided (
