Hello,

accurate number is not available.  But it must be covering 10% atleast as engineers are high number compared to doctors. Scope and stream types high. Every branch has atleast 3-4 domains which are related to other branch also. this shows a high diversity in different streams. In market world, there are many other career options also and it is  countless.

for more details, read the india skills report given by UNDP.

Hope it helps!
