3.1 The GDDS objectives for coverage, periodicity, and timeliness are summarized in Table 1. Recommended coverage features of the GDDS are listed under the “Components” column. However, some data categories or components are designated “as relevant” This designation recognizes that the relevance of a specific data category or component to an economy should be taken into account in the development of the statistical system. Where the periodicity, timeliness, or coverage components are designated as “encouraged,” countries are encouraged to develop and disseminate such data categories with the indicated periodicity and timeliness, but only after the main recommended components are regularly disseminated.
