Discover the Membership Types


The International Statistical Institute is an independent organisation of members that connect professionals in the fields of statistics and data science worldwide. We organise activities aligned with our strategic priorities. Some of the activities include: publishing scientific journals, hosting awards and prizes, and supporting our associations, committees and special interest groups that cover all topics of statistics and all sectors where statisticians work. This includes academia, government and industry. The ISI acknowledges the diversity of its members by offering different types of membership, discover them below.

ISI meetings are the only place for panels with contributors from vastly different areas of statistics, each drawing their own audience who would not otherwise participate in a discussion together.
