population density(redirected from Persons per square kilometre)
Also found in: Encyclopedia.
The number of organisms, usually people, living within a defined space, such as a city, county, or town. In the U.S., regions with greater population densities tend to have different health care problems than lightly populated ones. Conditions such as gunshot wounds, HIV/AIDS, and tuberculosis are more common in cities than in rural areas, but cities also tend to have a greater health care infrastructure and more professional resources than rural areas.
