According to 2011 census data, India has about 330 million houses and 247 million households. The household size in India has dropped in recent years, the 2011 census reporting 50% of households have four or fewer members, with an average 4.8 members per household including surviving grandparents.[331][332] These households produced a GDP of about $1.7 trillion.[333] Consumption patterns note: approximately 67% of households use firewood, crop residue or cow-dung cakes for cooking purposes; 53% do not have sanitation or drainage facilities on premises; 83% have water supply within their premises or 100 metres (330 ft) from their house in urban areas and 500 metres (1,600 ft) from the house in rural areas; 67% of the households have access to electricity; 63% of households have landline or mobile telephone service; 43% have a television; 26% have either a two- or four-wheel motor vehicle. Compared to 2001, these income and consumption trends represent moderate to significant improvements.[331] One report in 2010 claimed that high-income households outnumber low-income households.[334]
According to Chris Anderson of The Long Tail fame, this multiplicative impact seems to be related to a networking effect. Power law distributions seem to be created by “preferential attachments” among nodes in “scale-free” networks, which is to say that the winners are more connected than the losers. Similarly, there seems to be a clear relationship between connectedness, income and wealth. We can all optimize our practice by directing and optimizing our connections.
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.
