A population It is a set of individuals that inhabits a specific geographic space. For example: the population of Peru, the population of Cairo or the world population. The science that studies human populations is demography and uses two main concepts:
- Absolute population. It is the total number of individuals that inhabit a geographic area at a specific time.
- Relative population. Also called “population density”, it is the average number of inhabitants that inhabit a portion of the territory.
In turn, in the biology the term population is used to designate the set of living beings of the same species that inhabits a specific geographical place. For example: the population of bees in a hive or the population of red foxes that inhabit Japan.
Population in statistics
The statistics defines the population as a group of people, animals or things that share similar characteristics among themselves (different in relation to other populations), which are of interest for the study or analysis. For example: the medical students of a city or the employees of a factory. This term is used to carry out market research and advertising studies, censuses, sociological and anthropological studies, among others.
In statistical terms, the sample from a population as representative of its total. Thus, it follows that if certain characteristics are present in a portion of the population, then the total must be similar. When the total of a given population is taken, the study is called a census.
Characteristics of the populations
A population can have one or more of the following characteristics:
- Weather. Every population is in a historical or temporal moment.
- Space. Every population must have a delimited space.
- Age or gender. Certain populations may be comprised of an age range or a common gender.
- Likes / preferences. Certain populations can be delimited by their common preferences.
- Evolution. Every population varies and evolves over time.
- Homogeneity. Every population must share characteristics of similarity among its members. For example: Different applicants for a job form a population because they share the intention of applying for the position.
- Heterogeneity. A given population must be heterogeneous in relation to another population. For example: People of Chinese origin in the United States are similar to each other, but different from members of other populations.
