International Statistical Institute (ISI)

International Statistical Institute (ISI)

ISI is the oldest statistical organization in the world. It was founded in 1885 in London and currently operates as a non-governmental organization headquartered in The Hague. Since 1948, it has held consultative status with the United Nations Economic and Social Council (ECOSOC). ISI brings together statistical offices, international agencies, central banks, and academic communities worldwide, forming a global community of experts in the field of statistics.

The ISI supports the development and dissemination of statistics and promotes the profession of statisticians. It organizes the World Statistics Congress (WSC)—the largest industry event, held every two years in different countries, bringing together experts from a wide range of fields, from sampling methods and official statistics to data science. The Institute also conducts conferences and workshops, offers training (including on data ethics and data quality), awards prizes, and supports scientific publications. ISI is associated with a family of thematic associations, including the International Association for Official Statistics (IAOS), which focuses on official statistics and initiatives to improve their quality and understanding—especially in developing countries. On 17 February 2021, the then President of Statistics Poland, Dominik Rozkrut, PhD, was appointed President of IAOS for the 2023–2025 term.

Why is this important?

  • A strong expert network enables faster implementation of proven solutions—World Statistics Congress, webinars, and working groups facilitate the exchange of experience among statistical offices, academia, andexperts applying knowledge in practice.
  • Ethical and professional standards (including the ISI Declaration on Professional Ethics) strengthen trust in data by promoting transparency of methods, impartiality, and responsible use of information.
  • The development of methods and innovations covers modern sampling techniques, integration of administrative and private data, confidentiality protection methods, and applications of data science in official statistics.
  • Capacity building includes training, mentoring, and projects aimed at enhancing skills within statistical offices.
  • The profile of Polish statistics is rising thanks to active participation in congresses, publications, and engagement in ISI/IAOS committees—this is a tangible strengthening of Statistics Poland’s position in the international debate.
