Two mass events took place in Moscow today:
1. March "For the social rights of Muscovites."
2. "Marters" in defense of children.
We calculated the number of participants in all shares.

The march "For the social rights of Muscovites" began from Pushkinskaya. On passionate boulevard, 15 frames were installed, where I put 8 people with mechanical meters.

Their data on the framework:
1 - 209
3 - 118
5 - 126
7 - 146
9 - 159
11 - 123
13 - 175
15 - 116
Since the sample is even too good, just fold the numbers, divide by 8 and multiply by 15:
209+118+126+146+159+123+175+116 = 1172/8 = 146.5*15 = 2197.5
In total, about 2200 people took part in the march for the social rights of Muscovites.
At the second event, the framework was installed on both sides of Gogolevsky Boulevard. On the one hand, 8 frames.

And on the other - 11 frames.

For 8 frames we had 5 counters.
Their data on the framework:
1 - 872
2 and 4 - 1326
3 - 868
7 - 545
The sample here is also very good, so you can just fold and divide:
872+1326+868+545 = 3611/5 = 722.2 * 8 = 5777.6 through these frames.

The second side, data on the framework:
1 - 580
2 - 699
3 - 681
4 - 680
7 - 495
9 - 413
10 - 376
Here the load was not uniform, so we break the sample from the framework 1-6 and 7-10 (no one went through frame No. 11 at all):
580+699+681+680 = 2640/4 = 660*6 = 9960
495+413+376 = 1284/3 = 428*4 = 1712
Total through these frames: 9960 + 1712 = 11672
(On 3 meter, 1681 is scored by accident, the real figure is 681)

We summarize:
5777+11672 = 17449
In total, about 17,500 people took part in the "Mother of Mothers" in defense of children.
Data of the Ministry of Internal Affairs:
The primary ones were like this: social march - 500, in defense of children - 8000.
Adjusted data: Social march - 1000, in defense of children - 12,000.
Real numbers: social march - 2200, in defense of children - 17,500.
In general, the Ministry of Internal Affairs underestimated the number of participants in both events.
The counting of the social march was carried out by the guys-volunteers, whom I found. The counting of the march in defense of the children was carried out by myself and the team of the "Man and the Law" project, caused by help in this project.
Thank you so much! ;)
