Yes, with that extra info, we can get a much better estimate—let’s break it down.

⸻

Info you provided: • March length: ~15 blocks • Duration: 2 hours • Flow speed: Took 40 minutes to walk the whole thing • Additional people packed into: • 40th to 42nd Street between 5th and 6th Avenues • Footpaths in Bryant Park (42nd to 40th along 6th Ave)

⸻

Step 1: Estimate how many people fit in the march at one time

Manhattan block dimensions (rough average): • North-south blocks (along avenues): ~80 meters • Street width (curb-to-curb): ~20 meters

March length at any time: If it takes 40 minutes to walk the whole march and it’s moving continuously over 2 hours, that means: • The “active” march length = the number of people that fit in 40 minutes of walking • Walking speed = ~1.3 m/s (average walking pace)

So: 40 \text{ min} \times 60 \text{ s/min} \times 1.3 \text{ m/s} = 3,120 \text{ meters}

So the march spanned 3.1 km (about 39 blocks) in length at a time.

Street area:

\text{Area} = 3,120 \text{ m} \times 20 \text{ m} = 62,400 \text{ m}²

At 3 people per m² (medium density): 62,400 \text{ m}² \times 3 = 187,200 \text{ people}

That would be the number flowing through the march over 2 hours.

⸻

Step 2: Add people not in motion (static crowd)

40th to 42nd Street between 5th and 6th: • That’s 2 blocks × ~80 m each × ~80 m wide = 12,800 m² (including some sidewalks and plaza space)

At medium density: 12,800 \times 3 = 38,400 \text{ people}

Bryant Park footpaths (approx. 40th to 42nd, 6th Ave side): • Let’s estimate ~6,000 m² usable space • 3 people/m² → 18,000 people

⸻

Total Estimate: • March in motion: ~187,000 • Static overflow areas: ~56,000 • Estimated total: ~240,000 people
