One of the great challenges confronting contemporary India is the growing regional disparities. Prof. Amaresh Bagchi and NJ Kurian point out that the percapita income (1996-99) of Maharashtra is Rs 19,248 and that of Bihar is Rs 5,465. This maximum / minimum ratio was 1.87 in 1960-63, 2.50 in 1970-73, 3.28 between 1987-90 and is now at 3.52. The high-income states of Goa, Maharashtra, Gujarat, Punjab and Haryana, with a population share of 20% account for 33.8% of NSDP. Their share of NSDP was 27.6% in 1970-71.
