How big is that crowd, really?
Crowd estimates are political, and they are also computable: a dense crowd is about four people per square metre.

Frequently asked
How do you estimate a crowd size?
Measure the occupied area and multiply by density: about 1 person per m² for a loose crowd, 2.5 for a comfortable one and 4 for a packed one. Aerial photography plus a map is the standard method.
Why do crowd estimates differ so much?
Because organisers and authorities use different densities and different area boundaries, often by a factor of three or four. The photographs usually settle it.
