Brief Notes on Human Resources Class 8

People are a nation’s greatest resource. It is people with their demands and abilities that turn nature’s bounty into ‘resources’. Hence healthy, educated and motivated people develop resources as per their requirements. Human resources like other resources are not equally distributed over the world and differ in their educational levels, age and sex. Their numbers and characteristics also keep changing. The Government of India has a Ministry of Human Resource Development which was created in 1985 with an aim to improve people’s skills. This just proves how important people are as a resource for the country.

Distribution of Population

The way in which people are spread across the earth’s surface is known as the pattern of population distribution. More than 90% of the world’s population lives in about 30% of the land surface. The distribution of population in the world is extremely uneven since some areas are very crowded and some are sparsely populated. The crowded areas are south and southEast Asia, Europe and north eastern North America. Almost three-quarters of the world’s people live in two continents: Asia and Africa. 60 % of the world’s people stay in just 10 countries and all of them have more than a 100 million people.

Density of Population – Population density is the number of people living in a unit area of the earth’s surface. It is normally expressed as per square km. The average density of population in the whole world is 51 persons per square km. South Central Asia has the highest density of population followed by East and SouthEast Asia.

Factors Affecting Distribution of Population

Here are the major factors that affect distribution of population: 

Geographical Factors

Topography – People always prefer to live on plains rather than mountains and plateaus because these areas are suitable for farming, manufacturing and service activities. The Ganga plains are the most densely populated areas of the world while mountains like Andes, Alps and Himalayas are sparsely populated.

Climate – People usually avoid extreme climates that are very hot or very cold like Sahara desert, polar regions of Russia, Canada and Antarctica.

Soil – Fertile soils provide suitable land for agriculture. Fertile plains such as Ganga and Brahmaputra in India, Hwang-He, Chang Jiang in China and the Nile in Egypt are densely populated.

Water – People prefer to live in the areas where freshwater is easily available. The river valleys of the world are densely populated while deserts have a spare population.

Minerals – Areas with mineral deposits are more populated. Diamond mines of South Africa and discovery of oil in the Middle East lead to settling of people in these areas.

Social, Cultural and Economic Factors

Social – Areas of better housing, education and health facilities are more densely populated for example Pune.

Cultural – Places with religion or cultural significance attract people. Varanasi, Jerusalem and Vatican City are some examples.

Economic – Industrial areas provide employment opportunities hence a large number of people are attracted to these areas. Osaka in Japan and Mumbai in India are two densely populated areas.

Population Change

In Human Resources Class 8, the population change refers to change in the number of people during a specific time. The world population has not been stable. For an extremely long period of human history until the 1800s the world’s population grew steadily but slowly. Large numbers of babies were born but they died early too because there were no proper health facilities. Farmers were not able to produce enough to meet the food requirements of all the people. As a result the total increase in population was very low.

  • In 1804 the world’s population reached one billion.
  • In 1959 the world’s population reached 3 billion and this is often called population explosion.
  • In 1999 40 years later the population doubled to 6 billion. The main reason for this growth was that with better food supplies and medicine, deaths were reducing while the number of births still remained fairly high.

Birth rate – Births are usually measured using the birth rate which is the number of live births per 1,000 people.

Death rate – Deaths are usually measured using the death rate which is the number of deaths per 1,000 people.

Natural growth rate – Births and deaths are the natural causes of population change and the difference between the birth rate and the death rate of a country is called the natural growth rate. The population increase in the world is mainly due to rapid increase in natural growth rate.

Migration – It is the movement of people in and out of an area. It is another way by which population size changes. People may move within a country or between countries. Emigrants are people who leave a country. Immigrants are those who arrive in a country. Countries like the USA and Australia have gained in-numbers by in-migration or immigration. Sudan is an example of a country that has experienced a loss in population numbers due to out-migration or emigration. The general trend of international migrations is from the less developed nations to the more developed nations in search of better employment opportunities. Within countries a large number of people may move from the rural to urban areas in search of employment, education and health facilities etc.

Patterns of Population Change

Rates of population growth vary across the world. Although the world’s total population is rising rapidly not all countries are experiencing this growth. Some countries like Kenya have high population growth rates. With improving health care death rates have fallen but birth rates still remain high leading to high growth rates. In other countries like the United Kingdom population growth is slowing because of both low death and low birth rates.

Population Composition

Population has little to do with its level of economic development. For example both Bangladesh and Japan are very densely populated but Japan is far more economically developed than Bangladesh. People vary greatly in their age, sex, literacy level, health condition, occupation and income level. It is essential to understand these characteristics of the people to understand them as resources.

Population composition refers to the structure of the population. The composition of the population helps us to know how many males or females there are, which age group they belong to, how educated they are and what type of occupations they are employed in, what their income levels and health conditions are.

Population pyramid – It is a way of studying the population composition of a country is by looking at the population pyramid also called an age-sex pyramid. A population pyramid shows

  • The total population is divided into various age groups, for example 5 to 9 years, 10 to 14 years.
  • The percentage of the total population subdivided into males and females in each of those groups.

 The shape of the population pyramid tells the story of the people living in that particular country. The numbers of children (below 15 years) are shown at the bottom and reflect the level of births. The size of the top shows the numbers of aged people (above 65 years) and reflects the number of deaths.

The population pyramid also tells us how many dependents there are in a country. There are two groups of dependents — young dependents (aged below 15 years) and elderly dependents (aged over 65 years). Those of the working age are economically active.

Types of Population Pyramids

Some examples of types of pyramids are given below –

Kenya – The population pyramid of a country in which birth and death rates both are high is broad at the base and rapidly narrows towards the top because although many children are born a large percentage of them die in their infancy, relatively few become adults and there are very few old people. This situation is typified by the pyramid shown for Kenya.

India – In countries where death rates (especially amongst the very young) are decreasing the pyramid is broad in the younger age groups because more infants survive to adulthood. This can be seen in the pyramid for India. Such populations contain a relatively large number of young people and which means a strong and expanding labor force.

Japan – In countries like Japan low birth rates make the pyramid narrow at the base and decreased death rates allow numbers of people to reach old age. Skilled, spirited and hopeful young people endowed with a positive outlook are the future of any nation.

We in India are fortunate to have such a resource. They must be educated and provided skills and opportunities to become able and productive.
