Describe and explain, using examples which you have studied, the difference between the terms population density and population distribution.
Worked Solution & Example Answer:Describe and explain, using examples which you have studied, the difference between the terms population density and population distribution. - Leaving Cert Geography - Question 1 - 2008
Step 1
Define the term 'population density'
Answer
Population density refers to the number of individuals of a species present in a given unit area. It is usually expressed as individuals per square kilometer or per square mile. For example, the population density of Monaco is extremely high, as it has over 25,000 people living in just 2.02 square kilometers.
Step 2
Define the term 'population distribution'
Answer
Population distribution describes how individuals of a species are spread across a given area. This can inform us whether the population is concentrated in certain locations or is dispersed. An example of population distribution is the population of polar bears, which tend to be distributed in the Arctic region, primarily of northern Canada, Greenland, and parts of Russia.
Step 3
Explain the differences using examples
Answer
The primary difference between population density and population distribution lies in the focus of their definitions.
-
Population density quantifies how many individuals exist in a specific area, providing a numerical perspective essential for urban planning and resource allocation. For instance, a densely populated city like Tokyo has a high population density due to its large number of residents per area unit.
-
In contrast, population distribution emphasizes the pattern of placement of those individuals within that area. For example, rural areas may show a sparse population distribution, with individuals spread out due to agricultural land use. Together, these concepts give us a fuller understanding of demographic patterns and can demonstrate economic, geographical, and environmental implications.
