Day 12 of 28 Days of Tax Data
From Political Math
Here is a graph showing how the rich make more income and pay even more in taxes. While the upper middle class pay about the same percentage in taxes as the make. Finally the lower 60% pay less in taxes then their % of the nation income.

Day 5 of 28 Days of Tax Data
From Mint
There is a lot going on in this graphic. First, keep in mind that a “Tax unit” is either a single person, two people married filling jointly, or head of household (for example a single person with dependent child).
The gray dashed bars are the tax units that don’t owe any taxes to the Federal Government. What struck me was that these people can be found at all income levels.

Found the top graph via Paul Krugman’s blog. It is from a paper by Larry Bartels, professor of politics and public affairs at Princeton University.

I found a second graph in the same paper, showing the income inequality year to year (the 80/20 ratio measures the income inequality by dividing the income earned by someone at the 80th percentile by someone at the 20th percentile). Additionally, Bartels has highlighted the years Democrats and Republicans held the White House. Like a number of graphs on my site, you can see the increase in income inequality since the early 70s.

Data in the graphs are calculated from the Historical Income Inequality Tables compiled by the U.S. Census Bureau.
Addendum
