PARIS21 focuses its efforts on encouraging and assisting all low-income and lower middle income countries to design, implement, and monitor National Strategies for the Development of Statistics (NSDS) and to have nationally owned and produced data for all MDG indicators. Countries need to have an overall vision of the development of their national statistical system which will include the national, regional, and international needs; be part of the country development and poverty reduction policy; serve as a framework for international and bilateral assistance; include all parts of the data production units and address the issues related to the analysis and use of data; follow the international standards including quality; and build on all past and existing activities and experiences.
