Chapter 2: The World Population: Distribution, Density And Growth
Source: NCERT Official Textbook
The chapter then systematically examines the Geographical Factors (water availability, landforms, climate, soils), Economic Factors (minerals, urbanisation, industrialisation), and Social & Cultural Factors that influence where people choose to live.
A significant portion is dedicated to understanding population change. It introduces key concepts like growth rate, natural growth, and actual growth, along with formulas for Crude Birth Rate (CBR) and Crude Death Rate (CDR).
Migration is explained as the third component of change, detailing push and pull factors, and differentiating between emigration and immigration.
The chapter culminates with the Demographic Transition Theory, a model explaining how populations evolve from a stage of high births and high deaths (Stage 1) to low births and low deaths (Stage 3) as societies develop economically and socially.
The final section underscores the importance of population control measures, referencing Malthusian theory, for the sustainable management of resources.
