How to quantify people at public events


Knowing the number of people in a given location is important for the Government, as it will be able to plan policing, estimate the real need for professionals from different areas - doctors, nurses, firefighters, infrastructure, and even the number of glasses. water, ambulance and other benefits.

This calculation is easy to do, with a simple mathematical operation. It is known that a square meter (m²) can be occupied by a maximum of nine people in large concentrations.

Concentrations are divided into three categories: small, medium and large. At small concentration, three people per square meter are estimated; on average, six people; and in the large nine people per square meter.

By multiplying the average number of participants per m² by the floor space occupied, the average number of people attending a meeting will be reached. Here is the rule:

N P m² x H (m²) = T P A

Being:
N P m² = number of people per m²;
A = occupied area in m²;
T P A = Total number of people in the area.

Hypothetical example: Singer Roberto Carlos will perform in a free space 100 meters long by 60 meters wide. What is the capacity of spectators standing in this place?

We have the following data:
Number of people per square meter = 9
Square area of ​​the site? 100 x 60 = 6000 m²

Solving the problem 9 x 6000 = 54000.

Thus, 54000 is the maximum number of people standing there.

With just one look you can have the approximate audience. If the number of people is like a football league decision, the square area is multiplied by nine. If you think you have a lot of people but notice a lot of empty space, multiply by 6. And so on.
