For this chart, we built a simple data set based on statistics from the Internal Revenue Service, dividing different incomes into specific income brackets. The brackets themselves are not standardized.

A previous version of Income Upshot featured income information from the U.S. Census Bureau. Because of a lack of information at the higher income levels, we decided to swap out the data in favor of the current set from the IRS.

Hover over the blue bars to see how many households fall into each income range.
