What Is the Meaning of Social Science? 

In grades 6 to 8, social science was explored through stories of people, places, and events. As students enter grade 9, it is time to pause and understand what social science truly means and why it matters.

Human beings are social animals. We live in a society and depend on each other in many ways — right from birth, we connect with family, then friends at school, and then other people in society. This is because our lives are shaped by the environment, the institutions that govern us, the economic activities that meet our needs, and the traditions and ideas passed down through generations.

For example, if you live in Rajasthan, the climate is warmer, while regions near the Himalayas or Himachal have a cooler climate. Institutions include things like our Parliament, our Fundamental Rights, and our Fundamental Duties. Economic activities are those where money is involved — for instance, when you go to the market, buy pencils, and pay money in return, that counts as an economic activity.

In simple words, social science is the systematic study of human society. It does not only tell us what happens and where things are located, but also explains why events occur, how people live together, and how the environment influences life.

💡 Exam Tip: "Define social science" or "What is social science?" is a likely first question from this chapter. The NCERT-based answer is: Social science is the systematic study of human society.

How Are Our Lives Shaped by Society? 

Human beings depend on each other in many ways. When someone falls sick or needs help, we call our neighbours. When we celebrate festivals, we celebrate together with others.

Imagine celebrating Diwali completely alone, with no friends or family around — or cutting your birthday cake by yourself. It wouldn't feel good. This is exactly why societies exist.

While subjects like Physics, Chemistry, and Biology study the natural world, social science focuses on society — on institutions (like the legislature, executive, and judiciary), on culture (India's rich cultural heritage), and on human interactions. It helps us understand not only what happens in our social world, but also why it happens and how different aspects of life are interconnected.

A Day in Your Life: How Social Science Touches Everything

Think about a single day in your life, and you will notice social science working in the background at every step.

• You wake up in a house built with materials sourced from different places.
• The food you eat may come from various regions of the country — harvested, processed, and transported through the efforts of many people before it reaches your plate.
• You travel on roads planned and maintained by public authorities, such as the NHAI (National Highway Authority of India).
• You study in a school shaped by educational policies and programmes.
• The electricity you use is generated at distant power stations and delivered through a vast, complex network.

Even the simplest daily activities rely on systems of governance (like the traffic police you see on your way to school), economic production (the primary, secondary, and tertiary sectors contributing to GDP), and social cooperation.

💡 Try This: Write down five resources you use daily in your life. Note where they originate from, how they are generated, and how you use them.

Why Society Does Not Function by Chance 

Questions like these show that society does not function by chance — it is shaped by history, geography, institutions, resources, and human choices.

• History: India has a rich history — different rulers came and ruled, some tried to disrupt it, but we still emerged and are presenting ourselves well today.
• Geography: India's physical features are diverse — we have mountains, deserts, plains, peninsulas, and even islands, along with institutions that govern how we utilise our resources.

Social science helps us explore such questions and seek answers through careful observation, evidence, and logical reasoning. Here, "we" refers to social scientists, who observe, collect evidence, and respond logically. This same approach appears in the Class 9 History chapter on The Beginning of Civilizations, where the Palaeolithic, Mesolithic, Neolithic, Harappan, and Egyptian civilizations are studied by connecting evidence about when and where they existed.

Society has not always been as it is today — over thousands of years, it has changed greatly. Early human communities depended directly on nature for survival; over time, people learned to grow crops, domesticate animals, build settlements, and develop tools. People were once nomads searching for food, moving from place to place, until settlements were created. Villages developed into towns, and towns into cities. New ideas, inventions, and cultural exchanges gradually transformed the way of life. Knowledge was explored through observation, reflection, and dialogue.

The Concept of Panchamahabhuta 

This is a likely exam question, so it deserves careful attention. Panchamahabhuta refers to the five great elements available in nature:

1. Earth
2. Fire
3. Air
4. Water
5. Space

Panchamahabhuta describes the natural world as an interconnected system in which human life is embedded. It helps explain how the environment influences settlement patterns, occupation, architecture, food habits, and health practices — an idea that remains relevant as societies respond to environmental challenges, such as earthquakes, floods, and volcanic eruptions.

Vasudhaiva Kutumbakam and Global Interdependence 

Similarly, the idea of Vasudhaiva Kutumbakam, meaning "the world is one family," expresses the interconnectedness of human societies across regions and cultures. This is the same phrase India's Prime Minister referenced at the G20 Summit — that the entire world is like one family.

This sense of interdependence sits at the core of what social science seeks to understand when it studies global interaction and relationships. In simple terms: India imports about 80% of its crude oil from abroad, while it exports milk, wheat, and rice. Every country, in this way, works like part of a global economy — supplying what it has in surplus to other nations while importing what it lacks.

Early Reflections on Governance: Kautilya's Arthashastra 

Early reflections on governance in India also link political authority with public welfare and ethical responsibility. The Arthashastra, attributed to Kautilya (Chanakya) and composed about 2,300 years ago, examines administration, economic management, taxation, and the duties of rulers toward their people.

This shows that systematic thinking about governance and the economy existed long before modern academic disciplines developed. If a ruler treated people properly and worked for their welfare, they ruled for a long time.

Hence, social scientists observe people's lives, conduct interviews and surveys, examine documents, and compare different times and places — much like a census (jangana), where data is gathered from multiple families and studied to develop evidence-supported explanations. This is how social science explains both what endures and what changes, showing how the past shapes the present and how today's actions will influence the future.

Why Social Science Is Not a Single Subject 

Human society is complex, and no single field of study can fully explain it. For example, a drought affects crops, farmer income, government relief measures, and migration to cities — all at once. This means we are studying environment, economy, government policy, and society and culture together, all in one event.

Social science, therefore, is not a single subject but a group of related disciplines, each focusing on a different aspect of human life. Each discipline asks different questions, but they are all interconnected and together provide an understanding of society. The four disciplines are:

Geography as a Discipline of Social Science 

Geography studies the location and distribution of places, objects, material, and people. It examines both the physical features of the Earth and the human communities that inhabit it.

Physical geography looks at why earthquakes or floods happen more in certain places, and what determines climate and temperature differences. Human geography looks at how people interact with the natural environment and how places influence human life.

For example, if an area faces drought or low rainfall, people cannot easily continue living there — they migrate to places where they can find jobs suited to them. This is why India's Northern Plains, in particular, have the highest population settlement and the most farming activity.

Geography seeks to understand where things are located and found, and how nearby and distant places affect one another. It views the world as a system of interdependence, using maps, globes, atlases, geographical information systems, and infographics as tools. Geography also studies a temporal perspective — how things change over time, such as rocks that weather and erode over years, eventually converting into soil that moves elsewhere.

History as a Discipline of Social Science 

History is the study of the human past, through which society seeks to understand people's experiences, values, and changes over time.

There are multiple ways to interpret the past and transmit cultural values from one generation to the next. The Indus Valley (Harappan) Civilization is one example — the use of microlithic tools, the Great Bath, and well-developed cities and roads all show that people thousands of years ago were planning things in a proper way.

One of the oldest and most reliable forms of evidence is information collected through actual observation and experimentation — for instance, examining a palace's architecture, the soil beneath it, the stones used to build it, and the time period and economy it belonged to.

Modern historiography, by contrast, increasingly relies on empirical evidence and uses tools such as human genetics, carbon dating, archaeology, and other scientific methods to establish timelines. History writing draws on a wide range of sources to understand the social realities of the past, including:

• Archaeological and literary traditions such as travelogues, memoirs, correspondence
• Genealogical records
• Folklore and oral traditions
• Revenue documents

Material remains used to study the past are known as archaeological sources — these include monuments, architectural structures, excavated sites, art, objects, sculptures, and paintings. Examples referenced include the Samaveda manuscripts (National Museum, New Delhi), a traditional palm-leaf manuscript of the Tirukkural, a terracotta figure from the Indus-Saraswati civilization, a 12th-century sculpture of Vishnu, a Brahmi inscription from the Gupta period, a Kannada inscription of Emperor Krishnadevaraya at Hampi, a coin issued by King Samudragupta in the 4th century CE, and a Mughal coin issued during Jahangir's reign showing zodiac signs. These artefacts show how materials evolved over time — from terracotta to metal coinage.

Political Science as a Discipline of Social Science 

Political science is the study of governance, which informs us how and why power is distributed, how decisions are made, and how policies are implemented. In Parliament, laws are made, converted into acts, and then implemented across the country through the executive.

It is the study of the Constitution, government, and institutions of the state. Political science also studies social movements, nation-building, foreign policy, and the way power is exercised — whether through democracy, monarchy, dictatorship, or oligarchy, each with its own features.

In everyday life in India, the Panchayati Raj system importantly embodies grassroots democracy by giving citizens a voice in local development planning — this is your local self-government. This shows that political power exists not only within formal institutions but also in social relationships, customs, and ideas of legitimacy (following rules while doing something).

The study of politics in India began very early, alongside reflections on how society should be organised and governed. Politics was not treated as a separate discipline but was closely tied to the ideas of:

• Dharma — moral duty
• Artha — the economy
• Raj Dharma — the duty of the ruler

Early texts such as the Vedas, Upanishads, and Puranas (like the Vishnu Purana and Garuda Purana) discuss justice, authority, social order, and the responsibilities of kings and citizens — what we today call Fundamental Duties. Indian political thought is further articulated in works such as the Mahabharata and Shukra Niti, which address governance, law, and ethical leadership.

Among these, the Arthashastra stands out as a foundational text on politics and administration, detailing how a state should be governed, how taxes should be collected, how the army should function, and how the ruler should ensure welfare. Power was viewed as a responsibility rather than merely a privilege. This tradition helps us understand modern institutions such as the Panchayati Raj, which promotes local self-governance and public participation at the village level.

Economics as a Discipline of Social Science 

Economics helps us understand how individuals and societies decide to use limited resources to meet their needs. A simple example: if you receive pocket money of ₹1,000 per month, how you utilise it through the month is economics. At a country level, it is about how the government best utilises available resources.

Economics studies how goods and services are produced, exchanged, and distributed, and how these processes shape everyday life — from the food we eat and the clothes we wear to the jobs people do.

Economics explains decision-making by three groups:

• Consumers decide what to buy
• Producers determine what and how much to produce
• Government frames policies — for example, ensuring goods don't become too expensive for people to bear

This involves goals such as growth, stability, efficiency, and fairness — including policies like monetary policy and fiscal policy. In this way, economics is not only about numbers in the market but also about well-being, equity, and justice — for example, how the country responded when petrol and diesel prices rose, or how schemes like the PM Ujjwala Yojana provide subsidies to registered beneficiaries on LPG cylinders. Economic development therefore remains a central national goal, involving sustainable growth that meets present needs without harming future generations' ability to meet theirs.

How Does This Knowledge Help Us in Life? 

The house we live in, the water we use, the roads we travel — all of this is part of a system, and social science helps us understand how these systems are developed and how they function.

It also helps us understand how people live in harmony — speaking diverse languages, following diverse customs and practices, yet continuing to live together as one country over time. Social science explains these variations and outcomes through geographical, historical, cultural, and economic factors. This understanding builds respect and cooperation among communities, and it also helps us recognise how Indian culture binds diversity together through an underlying unity — fostering a sense of belonging and shared identity.

When you hear about issues such as environmental protection, public health, employment, and urban growth, you learn to ask informed questions about their causes, effects, and possible solutions. This habit of careful questioning and reasoning is essential for addressing problems that affect society — because we are aware citizens, and when events happen in society, we can question the government about the road map ahead.

The Future of Social Science 

Looking ahead, several forces continue to shape social science:

• Technological impact: Technological advancement — such as the growing use of AI — is shaping communication and community.
• Urban change and migration: Rapid urbanisation and global migration present new societal challenges as people move toward cities.
• Sustainability: Addressing climate change and sustainable development for a global future, so resources remain safe and preserved.
• Social cohesion: Understanding changing social connections, fostering harmony, and addressing equity — because society can only move forward when everyone progresses together ("sabka saath, sabka vikas").
