Population : Distribution, Density, Growth and Composition Summary
Population is a crucial aspect of any nation, and India, being the second most populous country globally, has unique patterns in population distribution, density, growth, and composition. This chapter provides students with a comprehensive understanding of these aspects, starting with the sources of population data, primarily through the decennial Census held every ten years. The chapter then shifts its focus to the distribution of population across various states and Union Territories, emphasizing how Uttar Pradesh, Maharashtra, and Bihar rank in terms of population size. The distribution is characterized by uneven patterns influenced by physical, socio-economic, and historical factors such as climate, terrain, and resource availability. North Indian plains and coastal regions are more densely populated compared to some hilly or remote areas. The chapter further explains how population density, measured as the number of persons per square kilometer, aids in understanding human-land relationships, with India’s average being three hundred eighty-two persons per square kilometer. Moving to population growth, the chapter delineates natural growth factors, including birth and death rates, alongside induced components like migration. It outlines four distinct phases of population growth in India, weighing historical contexts such as the population explosion phase from nineteen fifty-one to nineteen eighty-one, driven by decreased mortality rates and increased fertility rates. In terms of regional variations, significant differences in growth rates are noted, with states in southern India generally experiencing lower growth rates than those in northern India. Furthermore, the chapter addresses the youth demographic, noting the challenges they face and the government's initiatives aimed at empowering this crucial cohort through education and skill development policies. Lastly, population composition is analyzed, focusing on aspects such as rural-urban divide, linguistic diversity, and religious composition, which are pivotal in understanding social and economic frameworks within the country. The chapter underscores the importance of this knowledge for students, as it lays the groundwork for understanding broader socio-economic and cultural dynamics in India.
