This report is presented as a separate document from the survey's full report, so as to emphasize the importance of understanding the methodology and design of this national census of regulated businesses in Australia. This report reviews all of the procedures and steps undertaken from a data-collection and methodological perspective. It provides an important accompaniment to the major survey report published in conjunction with this methodological review. Both reports should be read together. This report summarizes the methodological approach, consolidation of assorted reports produced throughout the study, a review of sample use and response dynamics, and issues for consideration for future similar surveys.
