Demography is the scientific study of human populations, including their size, composition, distribution, and changes due to birth, death, and migration. The pivotal element of demography is population. Let us see why population is considered as the pivotal element of demography.

Importance of population in demography:

1. Size of the population: The size of the population is an important factor in demography. It helps to understand the social, economic, and environmental issues related to a particular area or region.

2. Composition of the population: The composition of the population refers to the age, sex, and other demographic characteristics. It helps to understand the population structure and its implications on society.

3. Distribution of the population: The distribution of the population refers to the spatial pattern of the population. It helps to understand the urban-rural divide, regional imbalances, and other geographic factors.

4. Changes in population: The changes in population due to birth, death, and migration are important in demography. It helps to understand the population growth rate, fertility rate, mortality rate, and migration patterns.

Conclusion:

In conclusion, population is the pivotal element of demography as it helps to understand the size, composition, distribution, and changes in the human population. Demography plays an important role in understanding the social, economic, and environmental issues related to a particular area or region.
