If you are looking for the ncert books class 11 sociology, here is what you need: NCERT prints the subject as two separate textbooks — Introducing Sociology and Understanding Society. Both are linked below, with the official NCERT PDF of every chapter in each book.
The split matters because both books number their chapters 1 to 5. A chapter number alone tells you nothing: “Chapter 2” could sit in either book. Match the chapter title, not the number, and you will open the right book first time.
The two Class 11 Sociology textbooks at a glance
| Book | Chapters | Printed pages | Book page |
|---|---|---|---|
| Introducing Sociology | 5 | 102 | Introducing Sociology (coming soon) |
| Understanding Society | 5 | 102 | Understanding Society (coming soon) |
Together the two textbooks run 10 chapters across 204 printed pages — each book exactly 102 pages — and carry 78 activities and 79 exercise questions.
The tables below give chapter, page, activity and question counts. Figure and table totals are not included: the diagrams in this edition are printed without captions. The chapters do not use named section headings, so section-level counts are not listed.
Which book is your chapter in?
Match your homework line against the ten chapter titles below, then confirm with any of the three routes that follow.
| Textbook | Chapter | Chapter title |
|---|---|---|
| Introducing Sociology | 1 | Sociology and Society |
| 2 | Terms, Concepts and Their Use in Sociology | |
| 3 | Understanding Social Institutions | |
| 4 | Culture and Socialisation | |
| 5 | Doing Sociology: Research Methods | |
| Understanding Society | 1 | Social Structure, Stratification and Social Processes in Society |
| 2 | Social Change and Social Order in Rural and Urban Society | |
| 3 | Environment and Society | |
| 4 | Introducing Western Sociologists | |
| 5 | Indian Sociologists |
Three ways to confirm the book:
- By chapter title — the reliable way. Every chapter title belongs to exactly one of the two books, so the title alone settles it.
- By the book’s name. The title is printed on the cover — Introducing Sociology or Understanding Society — and teachers usually name the book when they set the work.
- By the PDF file code. Official NCERT chapter PDFs begin with kesy1 for Introducing Sociology and kesy2 for Understanding Society. A file such as kesy104.pdf is Chapter 4 of Introducing Sociology.
You can check the file-code rule against the official source. Open kesy101.pdf — the official NCERT PDF of Sociology and Society, Chapter 1 of Introducing Sociology — and you will see that the book is free to download.
On the second book’s side, kesy201.pdf is the official NCERT PDF of Social Structure, Stratification and Social Processes in Society, Chapter 1 of Understanding Society.
The classic mix-up is Chapter 2. Terms, Concepts and Their Use in Sociology is Introducing Sociology’s Chapter 2, while Social Change and Social Order in Rural and Urban Society is Understanding Society’s Chapter 2. Both books have a Chapter 2, so a chapter number alone identifies nothing — carry the chapter title with the number.
What each book teaches
Introducing Sociology is the entry point and is usually taught first. Its chapters build the foundations of the subject: what sociology is as a discipline, the basic terms and concepts it works with, social institutions, culture and socialisation, and the research methods sociologists use.
Understanding Society carries those foundations further and is usually taught second. It covers social structure and stratification, social change and social order in rural and urban society, the relationship between environment and society, and the thinkers who built the discipline — first the Western sociologists, then the Indian sociologists.
