Human Resources
Overview
The world's greatest power — human beings. But how many people, where, how fast are they growing, what age groups — all of this is the accounting of human resources. Population = a country's greatest capital.
Typed Notes
Humans are the greatest resource
Land, water, machines — all of these exist — but it is humans who operate them. Human skill, knowledge, and hard work have transformed forests into cities, fields into factories, and books into satellites. This is why economists say: a country's greatest capital is its people. Educating people, measuring their potential, and giving them work — human resource development — takes a country forward (Japan — less land, but skilled people — a world power).
Distribution — where people are settled
People are settled unevenly: where water, climate, and jobs are good → densely populated: the Gangetic plains, Mumbai-Delhi, the Nile delta, Japan; where land is unfavourable → sparsely populated: the Sahara, Antarctica, mountains, deep inside forests. About 70% of the world's population lives in just a few countries (China and India — both with the highest populations). Factors: climate, water, agriculture, industry, government policy.
Density and growth
Density = population ÷ area (people/km²) — India ~380/km² (world average ~50) — but not the same everywhere: Bihar 1000+, Arunachal ~17. There are 3 drivers of population change: (1) Birth rate — births (larger families = more births); (2) Death rate — deaths (reduced due to medical improvements — this is why the world's population grew); (3) Migration — people moving from one place to another (villages → cities for jobs). The world has crossed 8 billion — but the growth rate is slowing (due to education and family planning).
Composition — the story told by the pyramid
The structure of population: (1) Age: young (0–14 — need for schools), working (15–59 — need for jobs), old (60+ — need for healthcare and pensions). India — a young country: more than half the population is of working age — 'demographic dividend' (the largest number of young workers in the world). (2) Gender: sex ratio = number of females per 1000 males (India ~943 — low — but improving). (3) Occupation: how many people are working. The age-sex pyramid (graph) — wide at the bottom (more young people — growing country) or wide in the middle (developed country).
Key Concepts
Revision ke liye ek nazar — exam se pehle yahi padhna hai.
- 01Human resources: a country's people — their numbers, skills, and work. An even bigger resource than machines — it is humans who run everything.
- 02Population distribution: where people are settled — uneven: areas with water and jobs are densely populated, while deserts and mountains are sparsely populated. About 70% of the world's people live in China and India.
- 03Population density = population ÷ area (people per km²). India ~380/km²; world average ~50/km².
- 04Population change: birth rate − death rate + migration (movement of people) = growth. The world is growing (8+ billion), but the growth rate is slowing down.
- 05Population composition: age (young/old), gender (male/female — sex ratio), occupation. The age-sex pyramid (graph) reveals a country's story — young India = strength.

Why are humans called the 'greatest resource'?
What is population density? Write India's figure.
What are the 3 drivers of population growth?
What does the age-sex pyramid show?
What is migration? What type of migration goes from villages to cities?
What is 'demographic dividend'?
Humans = the greatest resource (skill and hard work). Distribution is uneven: water and jobs → dense (Gangetic plains, cities), deserts and mountains → sparse. Density = population/area (India ~380/km²). Change: births − deaths + migration. Composition: age, gender, occupation; age-sex pyramid — young India = demographic dividend.
