The meaning of POPULATION DENSITY is the number of people living in each unit of area (such as a square mile). How to use population density in a sentence.
The meaning of density is a measure of how compact matter is. In simple terms, how much "stuff" is squeezed into a space. The more "stuff," or matter, is squeezed into a space, the denser it will be. What density means in science is a comparison of the mass of an object to its...
