Question

How is the index of concentration useful in the study of the population?

Answer 1

Index concentration is a very useful method to understand the uneven nature of the distribution of the population. For example, the population of Uttar Pradesh according to the 2001 census was 166 million, whereas the total population of India in the same year was 1027 million. So, the index of concentration for U.P. in 2001 was:

Index of Concentration = `("Population of U.P.")/("Total population of India") xx 100`

Index of Concentration = `(166)/(1027) xx 100`

Index of Concentration = 16.16

This means Uttar Pradesh accounted for 16.16% of India's total population in 2001, indicating its significant contribution to the overall population density of the country.
