Hi Aman, 

economics may provide a better foundation for your career as there is a steep rise in the economy and businesses these days. After graduation you can do MBA, And get placed in prestigious companies. 

This will give you a better scope and better opportunities. 

However, if you take sociology you can do post graduation and go on for Phd and be a professor at any college. That also has its own benefits. 

choose wisely.

good luck
