Whether it be population size or its share, the mutual distance between States has become larger since 1971. In such a circumstance, it would be wise to avoid using raw population size or shares in the calculus of determining these weights. For example, the population shares of Kerala and Uttar Pradesh (as of 2011) stand at 2.81% and 18.78%, respectively. (Moderation in population share means a kind of convergence in the gap in population share which is different from that of the raw population share. Such convergence happens when we take into account other characteristic composition of the population and adjust the raw shares accordingly.)
