Is this for India? Or the world? I'll assume you mean world as that's somewhat less harsh and less NIMBY. Alternatively, education, good government and a decent economy and birth rates fall. And there is then the bonus of no fascist/pseudo communist population control bent.

Globally? It took a few decades for Europe (criminalise poverty, ship the poor to the US/Canada/Australia), and lose most poor people in a couple of wars, followed by a giant injection of foreign funds for reconstruction.

India doesn't have the luxury of colonies, and emigrating from India is far harder than emigrating from mid-nineteenth century Europe was.
