If you’re in a crowd and people are close enough to bump into you, it’s probably too crowded.

Events like Crowds flocked to packed Halloween festivities in the South Korean capital of Seoul And this sadness At Houston’s Astroworld festival in November 2021, leading to multiple deaths and injuries.
However, organizers who have been studying the dynamics of crowd behavior and safety for more than 30 years said monitoring crowd density in real-time and regulating the flow of people into a venue can help prevent crowd-crushing incidents.
Population density can be calculated as the number of people per square meter, approximately one square yard. Younger than older and older people, the little ones occupy less space, but once they reach five people per square meter, as a rule things get uncomfortable, still said – and anything crowded is dangerous.
“When bodies touch, that high energy and density lead to these surges and crowding collapses,” Still said.
A sign that a crowd has become too dense is still called a “field of wheat harvest,” where people wander uncontrollably. He said he knows an example on the Internet videos During an Oasis concert in Manchester, England in 2005, a huge surge sent the crowd crashing towards the stage.
The key to preventing disaster is for organizers to monitor density and slow or stop the flow of people entering the area if it starts to get too high. He said it would be very difficult to reduce the crowd if the situation becomes too dense.
If an arena is too crowded, the performers must stop and ask everyone to take a step back. Over the years, many artists, including A$AP Rocky and Linkin Park, They have done it right.
If you’re in a crowd, he said, you can help stay safe by keeping an eye out for high-traffic areas and leaving the crowd if you don’t have enough personal space.
