What does population density mean in biology?
population density is a population-to-area ratio. It is the total number of individuals in a given area. In other words, it is the number of living things in a given area. The higher population density is, the more crowded the area is.
What does population density mean in ecology?
population density is the number of individuals living in a given area. A population density of one person per square km is low, while one person per square meter is high. If you live in an apartment, you have lower population density than if you lived on a large ranch. By contrast, a large population of grasshoppers living on a small area would have high population density.
What does population density mean in sociology?
Population density is also used in sociology. It refers to the number of people in a given area. The term is often used to describe a population per square mile or per hectare – the amount of people living in an area, such as a town or a country. This allows for the analysis of how the population of a region changes over time.
What does population density mean in medical language?
Often, population density is used to describe the number of people living in a given area. In a tightly packed city, there is a higher population density than in a sprawling suburb. However, population density is usually not used to describe the number of people living in your body.
What does population density mean in physics?
Population density is simply the number of individuals in a given area or volume. For example, consider a school of fish. If you looked out at the water from atop a tall cliff, you might see a school of ten thousand fish. If you looked at the water from a boat floating by, you might see a school of just ten fish. In both cases, the population density is the same: ten fish per square meter or one fish per square. Even though the number of fish in the school
