Data Analysis: 5 Star Academic Author Selling 3 Million implies :Great Author

India has about 2,17,00,00 Students Studying in Colleges.

Higher Education Institutions (Universities and Colleges) in India
Type of Institution Number E.g.
Central Universities (Public) 44 University of Delhi
State Universities (Public) 306 University of Mumbai
State Universities (Private) 154 Amity University
Deemed Universities (Private or Public) 129 Tata Institute of Social Sciences
Institution of National Importance (Public) 67 Indian Institute of Technology
Total Degree-granting Institutions 700
Affiliated Colleges (Public or Private) 35,539

Actual Numbers Today for Number of university Alone
State University 306 + 44 (central universities) = 350
Private Universities : almost 200+

Enrollment of Indian Students by fields of study
Field Number (‘000) % of Total

Growth of Higher education institution over years… In India.

statistics and data on different types of public and private universities in India


Latest data on student enrollment in universities and colleges in India.
out of 124 core or 1.24 billion population 28 million or  2.8 crore Graduate.

28 million/ 1240 Million = only 2.3% population Graduate in India.
2.8 million/1240 million = 0.2 % population does Post Graduation.
20 yrs back Wen i did my post graduation This % would be even less something like 0.002% you can see PG seats are doubling each year.. 2^10 = 1024 = around 1000.

so every year 1/2 means in 10 yrs (1/2)^10 = 1/1000 or if % of postgraduate today is 0.1 Postgraduate would be 0.001% 10 yrs back.

To Estimate How much would star Writer of Chemistry Would sell.

First science stream is around 19%-20% of whole population 4.8 million
Engineering is about 25% of Whole studying population. 5.4 million

There are Science subject in Graduation [ Physics, chemistry, maths, biology, Geology, bio chemistry, biotech, computer science, computer application, Electronics].

1 chemistry + 1/2 Bio chemistry +1/2 Geo are related to Chemistry = 2 out of 10.

from 4.8 million * 2/10 total market for graduate Students for chemistry.

Total market Size = around 1 million Books in Whole India.

In India There are 10 States/region many states uses regional language hence around 10 author from those regions via for that space depending on university. + 10 foreign Chemistry  author.

So 1 million = 100 thousand if we divide by around 20 , We get 5000 books per year.

Any time in college people can be in either of 1, 2 or 3rd  year.
Graduation year 1 : 5,000 Books
Graduation year 2 : 5,000 Books
Graduation year 3 : 5,000 Books
Total  in year : 15,000 Books are sold assuming 1 Book is picked by Student of every year for average good Chemistry author.

So Avg Good Chemistry Author sells : 15,000 books a year..
While Great 2 books are picked each year hence : 30,000 books a year… For Bsc.

Now Same would be for Btech [chemical engg program since almost same number studying science and engineering]  or 30,000

Chemistry Books Books Sold to Bsc Students = 30,000
Chemistry Books Books Sold to B.E. Students = 30,000
So Total :…………………………………………………………….60,000 Books a year.
Assuming :
Each Book cost Rs 400 and 5% is royalty income.

So, 5% of 400 = Rs 20.
Total income per year = …………………….60,000 X 20 = 12 Lakh rupees per year royalty.

While Selling 60,000 books a year. Its about 30 yrs of age when you Start writing your first book before that is very rare in science subject By 28 you finish your PHD itself.
Then you teach 2 yrs you would be 30.

So Assuming from first year itself book is block buster hit from age 30

if Author goes to Age 80 = in 50 yrs sold = 50 X 60,000 books = 30,00,000 Books.

If person crosses 30 Lakh mark really is STAR Author… is really Rare in this world..

Only Great authors Goes There in science field.


Compare it When you write or contribute for Journals as free volunteer SME What happens ?

My Contribution to printed Science Journal in circulation worldwide:
Last year I have crosse figure of 25 million printed magazine in subscription
And my free Blog on crossed 4 million Readership

Even I had best author award
Both of which are 25 million, and 4 million  are > 3 Million Books sold of star author.

combined both 29 million is ten Times figure of 3 million Books Sold.
Even I had Best author Awards flowing but Still more to come eager to write more..

Certainly Journals are 10 times more than Good Author in academics world.
I still feel writing book is all together and different Effort and meaning So I look forward to write more Books in future…

Kudos To All great Author which made world of Science better to young generation.
