BEA has prepared a series of papers that provide detailed descriptions of NIPA concepts and methodologies. The methodologies described in these papers are subject to periodic improvements that are typically introduced as part of the annual and comprehensive revisions of the NIPA's. These improvementswhich consist of definitional changes, new source data, and new estimating methodsare described in the SURVEY articles that cover these revisions. For example, see the articles listed in the section "Comprehensive revision of the NIPA's."
