Poverty rates in India's poorest states are three to four times higher than those in the more advanced states. While India's average annual per capita income was $1,410 in 2011 – placing it among the poorest of the world's middle-income countries – it was just $436 in Uttar Pradesh (which has more people than Brazil) and only $294 in Bihar, one of India's poorest states.
Portfolio income can come from multiple sources – interest/bond coupons, stock dividends, financial strategies including derivatives and capital growth.  Each offers some cash flow and some also offer potential capital gain with some risk from liquidity and volatile prices.  In this low-yield environment, many investors rely too heavily on cash flows and to pursue this are venturing further into riskier areas than they’d normally consider.
