Statistics is one of the main components of planning and decision-making support in all country's sectors. Accordingly, the importance of this manual that unifies the statistical and economic concepts and terms, which are used in the regional and international organizations and entities and the consultancy firms, lies in the fact that it is a general and comprehensive reference for the definitions, terms, and concepts that benefits researchers, concerned persons, academics and decision-makers.

This manual is relying on the Unified Directory of Statistical Concepts and Terminology in the GCC countries. The Planning and Statistics Authority has updated specific terms and listed new ones. We hope that it contributes to strengthening the statistical work transparency and raising statistical awareness for all groups utilizing the statistical data, information and indicators. It will be developed and updated by the Authority as needed.
