When it comes to describing a location that has too many people living in it, the term "over-populated" is commonly used. However, there are several other synonyms that can convey the same meaning. One such word is "crowded," which suggests that there are too many people in a specific area, making it difficult to move around or find personal space. "Teeming" is another term that indicates a large population and perhaps an unhealthy, unsustainable density of people. Other possible related terms include "congested," "jammed," "overflowing," and "swarming." When it comes to describing a location with too many people, it's essential to choose the right synonym to convey the intended meaning effectively.
