The Society’s most important scientific event is the Scientific Meeting, held in even-numbered years. Typically, a Scientific Meeting is attended by about 500 Members. During the event are presented about 200 papers, divided in plenary and specialized sessions and spontaneous contributions. It is usually structured in three days, possibly preceded or followed by satellite meetings.

The other most important event is the Intermediate Conference, held in odd-numbered years about a methodological or applied topic of particular national interest. Subjects included economics, business enterprises and official statistics. The organization of these Conferences is similar to that of the Scientific Meetings. Typically, it is attended by about 300 Members and during the event are presented about 100 papers divided in plenary and specialized sessions and spontaneous contibutions.

Scientific Meetings and Intermediate Conferences also provide the opportunity to call the Society’s annual general assembly, at which, according to the by-law, the budget is approved and the expiring offices are renewed. Scientific Meetings and Intermediate Conferences are both opened by the SIS President.
