Which Country has the second largest pool of Scientists and Engineers in the world?

India has the second-largest pool of scientists and engineers in the world, after China. This is due to India's strong education system producing millions of STEM graduates annually from IITs, NITs, and other engineering institutions. The country's IT and technology sectors employ vast numbers of engineers, both domestically and globally. While the UK, France, and UAE have skilled workforces, none match India's scale of technical manpower.
