International Association of Professional Congress Organisers (IAPCO) members collectively delivered 19,469 events across the globe in 2024, contributing an economic impact of over €17.8 billion (US$19.7 billion).
This represents a more than €3.5 billion increase from 2023 (19.8 per cent) according to their 2024 Annual Member Economic Impact and Business Strategy Report.

The growth in economic impact is driven by an increase of 2,425 conferences delivered by the 92 member IAPCO-accredited companies who collectively have 180 IAPCO-registered PCO offices around the world.
The growth in both the number of events and economic impact underscores the essential role PCOs play in driving economic growth, fostering innovation, and enhancing knowledge exchange on a global scale.
Looking forward, IAPCO members estimate strong numbers for the next three years. Currently, there are 1,969 conference contracts signed and confirmed without a designated destination or venue.
On Global Meetings Industry Day on April 3, 2025, Martin Boyle, CEO, IAPCO said each of the 19,469 conferences drove significant economic impact, as well as fostered innovation, facilitated knowledge exchange, and enhanced collaboration on a global scale.
“The growth of our sector remains a constant in our increasingly uncertain world. The drive for people to gather and share knowledge has never been stronger.”
In addition, IAPCO has seen significant growth in its membership.
“To be an IAPCO member is not easy to attain. However, the standard it represents is highly valued by associations, destinations, and organising committees who want to partner with a quality PCO. We believe the growth in our membership represents a commitment to excellence from both PCOs and clients, setting high standards within the industry,” he added.
