'Human Resources' is the final chapter of Geography for Class 8. It deals with the most important resource of all - human beings. The chapter explains the concepts of population distribution, population density, the factors affecting population growth, and the composition of the population.
The chapter begins by defining human resources. People are the greatest resource of a nation because their education, skills and knowledge enable them to develop and use other resources. The quantity and quality of the population determine the pace of development of a country.
The chapter then discusses the distribution of population across the world and within India. It explains that population is unevenly distributed, with some areas being densely populated and others sparsely populated. The factors affecting distribution include geographical, social, cultural and economic factors.
Population distribution means how people are spread across the earth's surface. The world's population is unevenly distributed. Some areas, like South and South-East Asia, Europe and the eastern parts of North America, are densely populated. Other areas, like the deserts, the polar regions and high mountains, are sparsely populated.
Population density is the number of people living in a unit area of land, usually per square kilometre. It is calculated by dividing the total population by the total land area. Population density helps us understand how crowded or empty a region is.
The distribution of population is affected by various factors. Geographical factors include topography (plains are more populated than mountains), climate (favourable climate attracts people), soil (fertile soil supports agriculture and dense population), water (availability of water attracts settlement), and minerals (mineral-rich areas attract industries and people).
Social, cultural and economic factors also affect population distribution. Social and cultural factors include the presence of religious and cultural centres. Economic factors include the availability of employment opportunities, industrialisation, urbanisation and the development of transport and communication.
Population change refers to the change in the number of people living in a particular area during a particular time. The population of the world is changing due to the processes of birth, death and migration. Population change is calculated on the basis of the number of births, deaths and migrants.
The natural increase of population is the difference between the birth rate and the death rate. The birth rate is the number of live births per thousand people per year, and the death rate is the number of deaths per thousand people per year. When the birth rate is higher than the death rate, the population increases.
Migration is the movement of people from one place to another. People migrate for various reasons, such as employment, education, marriage and better living conditions. Migration can be internal (within a country) or international (from one country to another).
Migration affects the population of both the place of origin and the place of destination. The place of origin loses population, while the place of destination gains population. Migration can be voluntary, when people move willingly, or forced, when people are compelled to move. The growth of cities is often due to rural-to-urban migration.
The patterns of population change vary across the world. In many developed countries, the population growth rate is low, and in some cases the population is declining. In developing countries, the population growth rate is high, which puts pressure on resources and services.
The high rate of population growth in developing countries is due to higher birth rates. Advances in medicine and public health have reduced the death rate, leading to a rapid increase in population in these countries. This population growth poses challenges for the provision of food, education, health services and employment.
The composition of the population refers to the structure of the population in terms of age, sex, literacy, occupation and other characteristics. The population can be divided into age groups: children (0-14), working-age population (15-59), and aged population (60 and above).
The sex ratio is the number of females per thousand males in the population. A favourable sex ratio is important for a balanced society. The literacy rate is the percentage of people who can read and write. The occupational structure shows the distribution of the population between agriculture, industry and services.
Human resources are the greatest resource of a nation. The development of a nation depends on the quality of its people. Educated, healthy and skilled people can use the natural resources of a country efficiently and contribute to its progress.
The chapter emphasizes that population should be seen not only as a problem but also as a resource. A large population can be an asset if the people are educated and skilled. Investment in education, health and skill development is essential for turning population into a productive human resource.
| Term | Definition |
|---|---|
| Population density | Number of people per unit area (per sq km) |
| Birth rate | Live births per thousand people per year |
| Death rate | Deaths per thousand people per year |
| Natural increase | Difference between birth rate and death rate |
| Migration | Movement of people from one place to another |
| Factor Type | Examples Affecting Population Distribution |
|---|---|
| Geographical | Topography, climate, soil, water, minerals |
| Social and cultural | Religious and cultural centres |
| Economic | Employment, industry, transport |
'Human Resources' completes our understanding of resources by focusing on people themselves. Population is unevenly distributed across the world, affected by geographical, social, cultural and economic factors. Population change is driven by births, deaths and migration, while the composition of the population reveals its age, sex, literacy and occupation. The chapter teaches us that people are the greatest resource of a nation. If a population is educated, healthy and skilled, it can transform other resources into wealth and progress. Therefore, investment in human development is the key to a nation's future.
