India's poverty line doesn't gets redrawn every year to account for the inflation and increased cost of living.
The current definition of the poverty line is daily earnings 27 rs for rural areas and 33 for urban, which is a ludicrously low number. Even beggars earn more than that. Of course we will have very low poverty if we use stupid ways to measure it.

Added to this is the shenanigans that our politicians play, where they may just lower the poverty line to declare a victory over it
