Approximately how many overseas attendees were at UK business events in 2025?

• A. Around 500 thousand
• B. Around 2 million
• C. Around 10 million
• D. Around 100 thousand

Answer: (B)

The idea here is to estimate international participation across all UK business events in a given year by adding up every overseas attendee from every event. That total grows with both how many events there are and how many international attendees each event attracts.

Two million is the most sensible scale for a full year: it reflects a large but plausible aggregate from many conferences, exhibitions, and summits hosted in the UK. A figure like 10 million would require an exceptionally huge year with extraordinarily high international turnout across numerous major events, while 500 thousand or 100 thousand would understate the reach of a busy annual calendar of international business events. So, around 2 million best fits the typical scope of overseas attendance across all UK business events in a year.
