how many people were at the protest

It isn’t possible to say how many people were at “the protest” without knowing which specific protest, city, and date you mean.

Crowd sizes can range from a few dozen people at a local demonstration to millions spread across a country, and even major human‑rights organizations and news outlets often only give rough estimates for large events. If you tell me which protest you’re asking about (for example, “the immigration strike in the US on January 30, 2026” or a specific city march), I can walk through how estimates are usually made and what different sources have reported.
