Wealth Concentrated in Top 10 Percent of Households (OECD Countries): Number 1
Among OECD countries, the United States stands far above the rest in the unequal distribution of wealth. While the Credit Suisse research shows that the top 10 percent of American families hold 69.2 percent, the OECD, using other date, estimates that nearly 80 percent of all wealth in the US is controlled by the top 10 percent of households.
