Emigration

Imagine you're at a crowded party, and the room is getting uncomfortably warm, prompting people to step outside for some fresh air. This scenario is similar to emigration in a population, where individuals leave a group to find better conditions elsewhere. Just like partygoers exiting a stuffy room to seek comfort outside, emigration involves people moving out of an area to improve their living situation, reducing the density and potentially alleviating stress in the original environment.
