1.4 Population group

The word population is often used to describe an individual population group sharing a certain feature. We may talk about the child population, population of working age or elderly population. In the same context, we often refer to population groups, which clearly defines the population according to some special characteristics. These special characteristics can be - as above - age, but the defining factors can be citizenship (alien population), refugee status (refugee population) or ethnicity (Sami population).

For biologists the word population also refers to an insect population, for instance. For statisticians population can be a group of people or objects examined.
