Question: How is the size of a big crowd estimated – such as on a march or any non-ticketed event?
Name: Neil, Chesham
Qualifications: Ex-police officer
Answer: On a march, an officer will stand at a fixed point and count the number of people who pass them in a given period of time.
They can then multiply this and estimate how many people are there in total.
The process is subject to human error.
