What is a population?
The word "population" came into our language from Latinand literally translated as "population". In the most general sense, a population is a group of beings (organisms) belonging to the same species, which for a long time live in one territory. The term "population" is used in various fields of science: in biology, medicine, psychometrics, ecology, geography and demography.
To better understand what a population is, here are some examples of using this word in different sciences.
- In ecology and biology, a population means individuals of one species who have a stable ability to self-produce and contact mainly within their group.
- According to genetics, the population is determined by the degree of crossing within the species. Populations are usually groups within a species or subspecies of living organisms.
- Population is considered the basic unit of measurement of any evolutionary process. It is the ecology as a science that considers its task to study the formation, development, dynamics of populations.
- In medicine, a population is understood as a set ofpeople, from among whom choose individual people for research. This set will subsequently be disseminated the results of medical research. The group of people for the study is determined by some general criterion, for example, by the presence of the disease.
