What does overpopulate mean?
Overpopulate is a formal verb meaning to fill an area, habitat, or other place with more people, animals, or organisms than are desired or can be comfortably accommodated. Its usual object is a place such as a city, region, or island, although the word can also describe a population that becomes excessively large. It is especially common in public policy, urban studies, and environmental science, where discussions focus on pressure on housing, infrastructure, food, or habitat. The related adjective overpopulated is often more frequent in everyday use, as when describing a crowded city, while the verb highlights population growth beyond a practical limit. The expression carries a generally negative connotation because the excess is treated as a problem rather than a neutral increase. It can describe both human crowding and the ecological effects of excessive animal or plant numbers. The directional force of over- clearly distinguishes this word from populate, which merely indicates filling a place with people.

Where does overpopulate come from?
The word combines the prefix over-, meaning “too much or excessively,” with populate, “to fill with people.” Populate comes through French from Latin populare, “to populate,” which was formed from populus, “people”; popular, population, populous, and depopulate belong to the same Latin root. Overpopulate is a modern English formation with the literal sense “populate excessively.”
