In India there are about 100 crore people. Above 18, there would be about 80 crore (May be more or less) people. Out of this 80, suppose, 10 are ST, 20 are SC, 10 are MBC, 5 are OBC, then call the rest of the 35 crore people as Backward Class (BC). This way, no one will crib about reservations, discrimination etc.. Summary is, Term the entire nation as "Backward"
