President Pranab Mukherjee today said India must reap its demographic dividend by improving the quality of teaching and focussing on skill development.

"Half of our population is below the age of 25 and in the next ten years the largest work force would be in India. This is demographic dividend. We must think how can we use this with the help of training, education and skills," Mukherjee said at a function organised by the Metropolitan Institution here.
