Demographic Component, Process, and Measure

Demographic Component, Process, and Measure

Demography is understood as the quantitive study of the size and structure of the population, the components of population change, and the factors that influenced them. It studies in detail fertility, mortality, and migration in scientific ways. For the demographic study, proper planning and strong supervision, and regular monitoring are needed because everything depends on the data that is derived from the survey and their analysis process. The demographic study is possible with the only demographic component, process, and measures.

Demographic Component, Process, and Measure

Demographic Component

Demographic components are factors that bring change in the population, such as birth death and migration. The other components that can also cause a change in population are marriage and divorce. In developing countries, marriage and divorce are very rare compared to developed countries. Therefore, these two factors are not taken as dominating factors. Birth brings a change in population by increasing or decreasing the population.

Demographic Process

The demographic process is the method of the way the population is changed. the methods through which populations are changed are fertility, mortality, and movement or migration. Birth occurs because of fertility, death occurs due to mortality and migration is a demographic process through which change is brought in population. Fertility and mortality are natural processes, which occur naturally. There is no human control over birth and death but migration can be done at one's will. Although migration can be forced or desired humans can control it. That is why migration is called an artificial demographic component as well as the process.

Demographic Measure

The demographic measure means measuring fertility, mortality, and migration by using some formulas so that fertility, mortality, and migration rates can be estimated. It is very important to find out the population situation, size, distribution, composition, etc, or a certain area at given times. Demographic measures are important to have an idea about the status of birth, death, and migration of certain places. These measures help us to plan better for people, place, and nation at a given time.

Types of Demographic measures

  • Fertility measures
  • Mortality Measures
  • Migration Measures
