About Us

Established in 1885, the International Statistical Institute is a non-profit, non-government organisation, with individual and institutional members in over 150 countries. 

It's main objective is to promote the understanding, development, and good practice of statistics worldwide by providing a welcoming environment for advancing statistical knowledge, learning best practices, sharing state-of-the-art developments, and by creating opportunities to network.


138 Years of History

Throughout its 138 years of history, the ISI has been a truly international organisation that has been bringing together statisticians of all different specializations and from different parts of the world to realise its mission of good understanding, development, and practice of Statistics.

Consultative Status with the United Nations

Since 1947 the ISI has had consultative status with the United Nations Economic and Social Council. This allows us to participate in the annual meeting of the United Nations Statistical Commission and other relevant United Nations' activities.

Network Around the World

The ISI network includes most of the national statistical offices around the world, and it also has links with international statistical organisations from the United Nations and others, and selected professional societies.

The international statistical community has provided me with robust challenge and support throughout my career. That's what colleagues do! And that's what you will find at the ISI.

Stephen Penneck, ISI President (2021-2023)
