Population Density
It refers to the number of people living per square kilometre of area. India is one of the most densely populated countries in the world, while Rajasthan has a lower density due to its desert terrain.
Sex Ratio
It is defined as the number of females per thousand males in the population. It is an important social indicator to measure the extent of equality between men and women in a society.
Age Composition
It refers to the number of people in different age groups (Children 0-14 years, Working age 15-59 years, and Aged 60+ years), which determines the dependency ratio and workforce availability of a nation.
Migration
The movement of people across regions and territories, which can be internal (within the country) or international (between countries). It is a major determinant of population change and distribution.
Literacy Rate
According to the Census, a person aged 7 years and above who can read and write with understanding in any language is considered literate. Literacy is a key indicator of quality of population.

Frequently Asked Questions
Why is population considered a crucial resource for a nation?
Population is the base for all other resources; human beings turn natural resources into useful goods and services through their skills and abilities.
What are the main causes of rapid population growth in India?
The main causes are a high birth rate combined with a declining death rate due to better medical facilities, healthcare, and control of epidemics.
Why is the population density of Rajasthan low compared to states like Uttar Pradesh or Bihar?
Rajasthan has a low population density mainly due to its harsh climatic conditions, arid land, and the presence of the vast Thar Desert, which limit water availability and agricultural expansion.
