Black GDP

The US Census estimates that blacks make up 13% of the population. The BEA estimates current US GDP at 11 trillion 734 billion. The World Bank has it at 11 trillion 667 billion. My rough estimate (13 percent of 12 trillion) is that blacks should account for one and a half trillion dollars of GDP.
The figure for black buying power in the united states varies between 600 billion and 700 billion. That is impressive as it places black america in the 14th to 9th spots on a list of the worlds' richest countries. Still, by population blacks should rest at number 3 only behind Japan or at 4 if you include the eurozone as a single entity.
