Densely populated refers to an area that has a high number of people living within a specific unit of area, usually per square kilometer or square mile. This term is often used to describe cities or regions where the population is concentrated in a relatively small space.
For example, a city like Tokyo or Mumbai is considered densely populated because a large number of people live in a relatively small area. This can lead to various challenges, such as increased demand for housing, transportation, and other resources, as well as potential issues related to pollution and public health.
Understanding population density is important for urban planning, resource allocation, and addressing social and environmental issues in densely populated areas.
