Wealth Inequality

The US central bank estimates that the top 1% of US households hold about 39% of the country's wealth, a term that includes assets such as property.

The top 1% also account for about 13% of income, after taxes and other federal transfers, according to a 2016 Congressional Budget Office analysis.

That's a higher share than in the UK, where the top 1% is estimated to account for about 8% of income and around 24% of overall wealth.

The richest 400 Americans now pay lower tax rates than any other income group.
