The Quarterly Bulletin has always contained a statistical annex, the size and coverage of which has changed from time to time. In recent years, increasing use has been made of tables and charts in other parts of the Bulletin to illustrate points in the text. Consequently, the statistical annex has come to be regarded as an occasional source of reference rather than as a necessary complement to other parts of the Bulletin. It has deficiencies as a source of reference because shortage of space precludes a long run of figures in most tables and detailed notes in each issue. A readership survey last year indicated that, while some tables were frequently used. others were scarcely if ever referred to.
