Population Summary

Chapter 6 – Population NCERT Geography Class 9 discusses the importance of human population in terms of growth and development. The population is a pivotal element in Social Studies. It is the point of reference from which all other elements are observed and from which they derive significance and meaning. ‘Resources’, ‘calamities’ and ‘disasters’ are all meaningful only in relation to human beings. The three major points of importance discussed in this chapter are mentioned below:

1. Population size and distribution
2. Population Growth and processes of population change
3. Characteristics or qualities of the population

Population with respect to India has been discussed in this chapter. The distribution of population and population growth is also the concern of the people in the country.
