Question

Give geographical reason

Population density is a function of population and area of a region

Answer 1

i. The distribution of land and population can be understood not just in terms of number of people living in a region but also in terms of people living in a unit area. This is called population density.

ii. It is given by the formula:

Density of population = `"Total population"/ "Total area (in sq. km.)"`

iii. More the area for a given population less is the density, as people have more land to reside in.

iv. Less the area for a given population, more is the density, as people have less land to reside in.

v. For example, India has 32.9 lakh sq. km area and supports 135.3 crores population whereas Brazil occupies 85.2 lakh sq.km area and supports 20.9 crores population. So the population density of India is more than Brazil.

Hence, we can say that population density is a function of population and area of a region.
