Earlier this year, Kauffman Foundation published a report on the key role that MIT has played in setting up and fostering companies to boost the economy. You can find the detailed report Entrepreneurial Impact: The Role of MIT on the Kauffman Foundation website.
Key points highlighted by the report are:
1. There are about 25,800 companies set up by MIT alumni
2. Over 3.3 million people are employed by these companies
3. These companies generate annual world sale of about $2 trillion, which is equivalent to the 11th largest economy in the world.
This is a very detailed report and shows the important role MIT has played globally to foster entrepreneurship and innovation. If you are considering applying to MIT in Fall 2009 or if you are waitlisted by MIT. I would highly encourage you to read this report to better understand MIT and its culture.
