Is it true that the average consumption of PDS food grains in the Southern states

Is it true that the average consumption of PDS food grains in the Southern states is much higher than that in Madhya Pradesh? Explain.

This is true because in Madhya Pradesh only 5% of wheat and rice consumption of the poor is met through the ration shops.
In contrast consumption in southern states is very high in the range of 3-4 kgs per person per month and in Madhya Pradesh it is 500 gm per person per month.
