The wealth held by the top 9 billionaires in the country is equivalent to the wealth of the bottom 50 per cent of the population, it added. Since the year 2004, the poorest 10 per cent of the country (13.6 crore people) have continued to remain in debt, the Oxfam report added. "India's top 10 per cent of the population holds 77.4 per cent of the total national wealth. The contrast is even sharper for the top 1 per cent that holds 51.53 per cent of the national wealth.The bottom 60 per cent, the majority of the population, own merely 4.8 per cent of the national wealth," Oxfam report said.
