The income gap between the richest 1% of Americans and the other 99% widened to a record margin in 2012, according to an analysis of tax filings.
The top 1% of US earners collected 19.3% of household income, breaking a record previously set in 1927.
Income inequality in the US has been growing for almost three decades.
Overall, the pre-tax incomes of the top 1% of households rose 19.6% compared to a 1% increase for the rest of Americans.
And the top 10% of richest households represented just under half of all income in the year, according to the analysis.
