π Chapter 7 β Human Resources
π’ Introduction
- The most important resource on Earth is human beings because they use knowledge, skill, and technology to utilise natural resources.
- Without people, natural resources have no value.
- Thus, human resources = total number + skills + abilities of people.
πΉ 1. What is Human Resource?
- Definition: The people who make up the workforce of a country.
- It includes:
β Physical strength
β Intelligence
β Creativity
β Technical skill
β Organisational ability - Key idea: βPeople are a resource only when they are educated, healthy, and skilled.β
π‘ Example:
- A coal mine is useless without miners, engineers, and machines.
- A fertile field is unproductive without farmers.
πΉ 2. Distribution of Population
- Population of the world is not evenly spread.
- Factors that decide where people live:
π± Favourable Areas (Dense Population):
- Plains & Fertile Land β Ganga plain (India), Nile valley (Egypt).
- Mild Climate β Europe, SE Asia.
- Good Transport β Coastal areas, river valleys.
- Industrial & Trade Centres β Mumbai, Shanghai, New York.
ποΈ Unfavourable Areas (Sparse Population):
- Extreme Climates β Sahara desert, Polar regions.
- Dense Forests β Amazon basin.
- High Mountains β Himalayas, Andes.
- Remote Islands β Arctic regions.
π Conclusion: Human population is clustered where life is easier.
πΉ 3. Population Density
- Definition: Number of people living per square kilometre.
π World Examples:
- High Density: Bangladesh (1200+ people/kmΒ²).
- Medium Density: India (400+ people/kmΒ²).
- Low Density: Australia (3 people/kmΒ²).
π‘ India Case Study:
- Dense in Uttar Pradesh, Bihar, West Bengal (fertile plains).
- Sparse in Rajasthan, Ladakh (desert, mountains).
πΉ 4. Population Change
- Definition: Increase or decrease in number of people.
- Measured by:
π Birth Rate: Number of live births per 1000 people/year.
π Death Rate: Number of deaths per 1000 people/year.
π Migration: Movement of people in/out of an area.
π‘ Formula:
Population Change = Births β Deaths + Migration
πΉ 5. Patterns of Population Change in the World
- π Developed Countries: Low birth rate + low death rate β Slow growth.
- π Developing Countries: High birth rate + falling death rate β Rapid growth.
- ποΈ Least Developed Countries: High birth rate + high death rate β Slow growth.
π Example:
- Japan: Population shrinking due to ageing + low births.
- India: Growing fast due to high births.
- Africa: High birth rate but also high deaths (disease, poverty).
πΉ 6. Population Pyramid (AgeβSex Pyramid)
- Definition: Graphical representation of age and gender structure.
β³ Three Types of Pyramids:
- Expansive Pyramid (Triangle shape):
- Wide base = High birth rate.
- Example: India, Nigeria.
- Constrictive Pyramid (Beehive shape):
- Narrow base = Low birth rate.
- Example: Japan, Germany.
- Stationary Pyramid (Rectangle shape):
- Balanced births & deaths.
- Example: USA.
π Why useful?
- Shows growth trends.
- Helps in planning schools, hospitals, jobs.
πΉ 7. Working and Non-Working Population
- Working Population (15β59 years):
- Backbone of economy.
- Engaged in jobs, industries, farming, etc.
- Non-Working Population:
- Children (below 15).
- Elderly (above 60).
π‘ A country with more working-age people = demographic dividend (advantage).
πΉ 8. Human Resource Development (HRD)
- Meaning: Improving peopleβs skills, knowledge, and health to make them productive.
- Main components:
- Education π
- Spreads awareness.
- Improves skills & innovation.
- Example: IITs, IIMs in India produce global professionals.
- Health π₯
- Healthy people = More productive.
- Malnutrition, diseases reduce efficiency.
- Example: Kerala has high literacy + better health = higher HDI.
- Skill Training βοΈ
- Vocational and technical education.
- Example: ITI institutes, Skill India Mission.
πΉ 9. Human Development Index (HDI)
- Developed by UNDP (United Nations Development Programme).
- Measures:
β Life Expectancy
β Education (literacy)
β Income (per capita)
π Examples:
- High HDI Countries: Norway, Switzerland, Japan.
- Medium HDI: India, Brazil.
- Low HDI: Many African nations.
πΉ 10. Importance of Human Resource
- People are the real wealth of a nation.
- They use technology to turn raw materials into useful products.
- Example:
- Coal β Electricity β Industries.
- Cotton β Cloth β Fashion market.
π‘ Key Idea: Human beings are not just consumers, but also producers.
πΉ 11. Challenges of Human Resources
- Overpopulation β Strain on food, jobs, housing.
- Unemployment β Idle manpower β poverty.
- Illiteracy β Low awareness, low productivity.
- Poor Health β Reduces working capacity.
- Unequal Distribution β Some areas over-crowded, some underpopulated.
πΉ 12. Steps to Improve Human Resources
β
Invest in education.
β
Improve healthcare facilities.
β
Provide skill training.
β
Control population growth.
β
Ensure gender equality.
β
Encourage research and innovation.
π Summary (Key Points to Remember)
- Human beings are the most valuable resource.
- Population distribution depends on climate, land, resources.
- Population pyramid helps understand ageβsex composition.
- Human Resource Development improves a nationβs progress.
- HDI compares the quality of life between countries.
- Balanced growth of population = sustainable development.
