Question

What do you mean by the term density of population of a country?
A) The average number of deaths per annum
B) The average number of births per annum
C) The average number of people living in one hectare
D) The average number of people living in one square kilometre

Answer 1

Hint:
Each unit of land has a limited capacity to support people living on it. Therefore, it is essential to understand the ratio between the numbers of people to the size of land. This ratio is known as the density of population.

Complete Answer:
The density of population is expressed as the average number of people living in one square kilometre. It provides a better understanding of the spatial distribution of the population in relation to land. Population density is calculated as the number of persons per unit area or per square kilometre. Our country is one of the most densely populated countries in the world. As of 2011, the density of population in India was 382 persons per sq km. There has been a steady increase in the density of population in India over the last five decades as the density of population increased from 117 persons per sq km in 1951 to 382 persons per sq km in 2011. The spatial variation of population densities in the country varies from as low as 17 persons per sq km in Arunachal Pradesh to 11,297 persons per sq km in the National Capital Territory of Delhi. This shows the pattern of uneven distribution of population densities at the state level.
The formula for calculating the density of population is
$\text{Density of Population }={\displaystyle \frac{\text{Population}}{\text{Area}}}$
Here, population is the respective population of the particular area and area is the size of the area in square kilometres.

Thus, option (D) is correct.

Note:
Many factors affect the density of the population. These are the geographical factors, which include the availability of water, landforms, climate, and soils, the economic factors, which include minerals, Urbanisation, and industrialization, and lastly social and cultural factors.
