The mission, vision and strategic objectives of the NSI are defined in the Strategy for the Development of the National Statistical System of the Republic of Bulgaria, 2021-2027. The Strategy is drafted by the NSI, in collaboration with the bodies of statistics and the Bulgarian National Bank, in pursuance of Art.7, sub-article 1, point 3 of the Statistics Act. According to the Strategy, the vision of the NSI is to guarantee modern and efficient work of the National Statistical System that provides high quality of the statistical information production and public trust in statistics by users and partners.

The NSS’s mission in the Republic of Bulgaria is to provide impartial, objective, timely and accurate information on the state and trends of changes in the economy, socio-cultural environment, demography and environment to accommodate the growing information needs of all user groups.

The official statistical information – product of NSS – is intended for analyses and scientific studies, planning, prognosis and making managerial decisions at micro and macro level. The statistical information products and services are directed to the:

  • Bodies of state administration and local authorities;
  • Business sector and non-government organizations;
  • Scientific and academic society;
  • Mass media;
  • EC, UN, IMF and other international organizations;
  • Individual citizens.

In achieving its strategic and operational goals and carrying out specific activities during the 2021-2027 period, the NSS will be steered by the Fundamental Principles of Official Statistics of the UN and the European Statistics Code of Practice, as well as the following key principles, necessary for the implementation of the Strategy:

  • reliability and high quality
  • innovation
  • adaptability to extraordinary needs
  • willingness to cooperate
  • sustainability of development 
  • proactivity.



The development of the National Statistical System during the 2021-2027 period pursues the following four strategic goals:

  • Modern and effective National Statistical System
  • High quality and confidence in official statistics
  • Transition from statistics to value-added statistics
  • Active cooperation with national and international partners

NSS produces statistical information in compliance with the best practices by using the available data sources, as well as the modern methods for collecting, processing and disseminating data. The official statistics is basis for the elaboration of all public policies both at national and European level, and ensures informed making of managerial decisions. Its role is of key importance for the growing information flow, including fake news.

The production of statistical information is impossible without the timely and quality providing with primary data by business, households and citizens. From the society’s perspective, an effective National Statistical system is a system, which produces useful and significant information for the management at micro- and macro-level at the least possible expenses. The core condition for the successful dissemination of the statistical information is its providing in comprehensible and accessible form.

The sustainable development of NSS is impossible without the existence of proper legal framework and functional medium. A more effective cooperation with Eurostat and the national statistical systems of the other Member States is an important condition for the full integration of our national statistics within ESS. The highly qualified and motivated human resources are key factor for implementation of the mission of NSS and the achievement of the strategic and operational goals of the development for the 2021-2027 period.
