What does population densitity mean in geography?
Stated rather simply, population density is a measurement of the number of people in an area relative to its size. Like many geographical concepts, it's not an exact number. It's usually more of an average or even an estimate. With this in mind, population density is most often calculated by the number of people per square kilometer.

How do you find the density?
The formula for density is the mass of an object divided by its volume. In equation form, that's d = m/v , where d is the density, m is the mass and v is the volume of the object. The standard units are kg/m³.
What is unit of density?
Density is commonly expressed in units of grams per cubic centimetre. For example, the density of water is 1 gram per cubic centimetre, and Earth's density is 5.51 grams per cubic centimetre. Density can also be expressed as kilograms per cubic metre (in metre-kilogram-second or SI units).

Who Discovered density?
ArchimedesWho discovered density? Density was discovered by a Greek mathematician and engineer named Archimedes. He was born in the city of Syracuse, which was the heart of art, commerce and science, and his father, Phidias, was a mathematician and an astronomer.
What do you mean by density of population?
Population density is the concentration of individuals within a species in a specific geographic locale. Population density data can be used to quantify demographic information and to assess relationships with ecosystems, human health, and infrastructure.
How does density affect the world?
Population density can have a negative impact on our environment and natural resources. These pressures can lead to deforestation, result in overcrowding, and could lead to the destruction of our planet's delicate ecosystem.
Where is density used in real life?
Everyday Density Examples In an oil spill in the ocean, the oil rises to the top because it is less dense than water, creating an oil slick on the surface of the ocean. A Styrofoam cup is less dense than a ceramic cup, so the Styrofoam cup will float in water and the ceramic cup will sink.

What is an example of low density?
For example, wood floats on water because there is plenty of space between the atoms in the wood – that is - it has low density. An iron nail sinks in water because the atoms are tightly packed in the iron nail with very little space between them.

What does density mean for kids?
Density refers to how much mass there is in a particular space. Imagine a drawer full of socks. It has a certain density. If you take a sock out, the density of the drawer changes. This is because the mass of the socks has changed, but the volume of the drawer has stayed the same.

Why are deserts so low in population?from en.wikipedia.org
Deserts have very limited potential for growing crops as there is not enough rain to support them. Thus their population density is generally low. However some cities in the Middle East, such as Dubai, have been increasing in population and infrastructure growth at a fast pace.
