Scientific Congresses

The ISI World Statistics Congresses (WSC) take place once every two years in different countries and cities/venues. Though the ISI organizes them, we work closely with the country’s National Statistics Office and Society.

The ISI World Statistics Congresses(WSCs) are the flagship events of the ISI, characterized by a rich Scientific Programme, a unique Social and Cultural Programme, an Administrative Programme, Short Courses Programme, Satellite Meetings, and Awards Ceremony. 

The WSCs and their associated events are the highpoint of activities of the ISI. These

  • Are highly valued by our membership
  • Provide opportunities for members to meet and network. 
  • Takes place once every two years in different countries and cities/venues. 

During this event, all our Associations, Committees, members, and participants involved in statistics worldwide, come together to participate in the many different activities of WSC for an entire week, and in associated activities immediately before or after that week.

Though the ISI organises WSCs, we work closely with the venue country’s National Statistics Office and Society.

Scientific Programme

Each WSC has a rich Scientific Programme, which is grouped into two types of sessions:

  • Invited paper sessions (IPS)
  • Contributed and posters sessions (CPS)

Administrative Programme

A full Administrative Programme includes meetings of the various groups of the ISI and its Associations:

  • Executive committees
  • Councils
  • General assemblies
  • Committees

This includes special interest meetings relevant to the particular WSC.

Social Programme

The Social Programme makes the WSC an event to remember and gives participants a flavour of the culture of the host country. This programme also includes daytime activities for accompanying persons.

Satellite Meetings

These are associated with the WSC and they take place in or close to the host city before and after the main WSC week. 

They combine with the WSC to provide an overall outstanding international statistical event which is memorable in every way.

Short Course Programme

Short Courses are held two days before the World Statistics Congress. They are organized by the ISI with the support of participating institutions.

During this programme our highly regarded instructors helps participants develop the analytical and critical thinking needed to be adaptive and responsive to the dynamics of a rapidly changing world.


In the WSC Awards Ceremony, ISI & Associations recognise, celebrate and honour those who have made outstanding contributions to the field of Statistics and Data Science.
