Since 1960 the UIA has prepared statistics on the international meetings that have taken place worldwide in the preceding year. This work is based on routine research and surveys undertaken by the UIA. Meetings taken into consideration include those organized and/or sponsored by international organizations, i.e. the sittings of their principal organs, congresses, conventions, symposia, regional sessions grouping several countries, as well as some national meetings with international participation organized by national branches of international associations.

Highlights include:

• Number of meetings per city and per country, with indications of their market share
• Top international meeting countries and cities per year
• Trends in participant numbers and meeting dates
• Top 100 ranking
• Five year preview of future top countries and cities where meetings are planned
